The '''Stage Builder''' ({{ja|ステージ作り|Sutēji-zukuri}}, ''Stage Maker'') is a feature in ''[[Super Smash Bros. Brawl]]'', {{forwiiu}}, and ''[[Super Smash Bros. Ultimate]]'' that allows players to create their own custom [[stage]]s by using the given stage parts, and in ''for Wii U'' and ''Ultimate''{{'}}s case, drawing on the [[Wii U GamePad|GamePad]] and the [[Nintendo Switch]], respectively. Players can also choose from a variety of backgrounds and pick any song on the games' soundtracks.

Builders must choose to create a small, medium, or large stage, which will affect the number of places parts can be placed in and the location of [[blast line]]s. Next, the builder selects a theme: a mountain, a building in ruins, or a futuristic chamber. Each theme has its own set of special stage elements which allow for slight variations in stage design depending on what theme is used. The final step before building is picking {{SSBB|music}}, which can be any track that has been unlocked. Only one track may be chosen per stage, though the player may change it to a different track after the stage has been built. Users must place a minimum of four horizontal areas (for spawning points) for the game to allow their stage to be saved.

There are different structures and building materials the player can use depending on the background chosen earlier. There are three different sizes for most of the structures, with the one exception being the {{b|ladder|stage element}}. Parts cannot be freely placed and are restricted to being placed on a grid, with the size of the grid changing with the stage size; 10x8 on small stages, 14x11 for medium, and 18x14 for large (each grid cell is 20x20 [[unit]]s). The player can use parts until they reach the stage's capacity of 8,000 (regardless of stage size). Each piece used will use up a certain amount of capacity for the map, and some pieces take up more capacity than others. Once ready, the player can test the stage through the editor; however, the player is limited to using {{SSBB|Mario}} with the default controls for the controller being used. One can also switch back to the editing screen to make more changes. Custom stages are compatible with SD cards. The limit to the number of custom stages a player can have depends on how much room one has in their internal [[Wii]] memory or [[SD card]]. The player can also send stages to their friends.

Types of parts the player can use in this mode come in three categories:

*Floors include objects such as like blocks, [[platform]]s, ramps, and stairs.

*Structures include trees, mushrooms, crates, and rock arches.

*Features include [[Drop Blocks]], {{b|spring|stage element}}s, ladders, and [[conveyor belt]]s

Custom stages could be uploaded to a ''Brawl'' server, with players also receiving a random stage uploaded by a different player via the [[Smash Service]].

There are three categories of parts: floors, structures, and features. The following table gives the name (unofficial), size in grid spaces, capacity usage, and description of each part.

In {{forwiiu}}, the Stage Builder was changed immensely. Players now have much more freedom when creating stages, with the ability to draw platforms of any shape using the [[Wii U GamePad]]. The GamePad is the only way to create or modify the stage, with other controllers only being allowed to highlight buttons and perform the actions of said buttons, such as undo or save. An option is given to either make the platform grabbable by players or not. However, there are much fewer stage parts than ''Brawl'', being limited to cannons, springs, moving platforms and magma. Jump-through platforms can be made by making a line and tapping it. All objects' and platforms' locations snap to an invisible fine grid that has a resolution of 1x1 [[unit]]. A visible grid with 5x5 unit cells can be displayed by pressing the [[X]] button for easier alignment when placing or drawing. The grid also shows where in-game boundaries will be, with a green border showing where the camera boundaries are, and a red border for the [[blast line]]s. Walk-off stages can be created because of their placement.

When testing a stage, pausing and pressing ZL or ZR on the GamePad will allow players to select their character, an opponent character (including a second player), and customized controls and names. {{SSB4|Mii Fighter}}s can not be selected.

Five backgrounds share two textures that can be given to drawn platforms, and each background has three unique textures of their own.

! Image !! Name !! Information

| [[File:SSBUStageBuilderSpring.png|128px|center]] || Spring (small) || Works just like the small spring in ''Brawl'', giving characters an upward speed of <code>25g+1.625</code> [[unit]]s/[[frame]] with '''g''' being the character's {{h1|gravity|Super Smash Bros. 4 gravity values}}. Depending on the character's gravity, they'll reach a height between ~80-105 units (roughly 3-4 times height of [[Pokémon Stadium 2]]'s platforms) from the spring's top. 11 units wide, 11 units tall.

| [[File:SSBUStageBuilderSpring2.png|128px|center]] || Spring (large) || A larger spring that bounces characters higher, working like the large spring in ''Brawl'' and giving characters an upward speed of <code>25g+2.825</code> units/frame with '''g''' being the character's gravity. Depending on the character's gravity, they'll reach a height between ~140-160 units (roughly the height needed to do a reverse [[Hyrule Jump]] and then to reach the slanted platform on the right of Temple) from the spring's top. 25 units wide, 16 units tall.

| [[File:SSBUStageBuilderCannon.png|128px|center]] || Cannon (weak) || Similar to [[Barrel Cannon]]s. Launched characters deal 4% upon contact. Characters are launched at a speed of 4.4 units/frame (actual value is 5 but characters aren't launched for a few frames). For the next 60 frames (1 second), characters are unable to perform most actions, have their [[gravity|upward speed decreased]] by 0.1 (straight up) to 0.025 (sideways) per frame, and downward speed decreased by 0.05 per frame; after the 60 frames both the upward and downward speed decrease is set to 0.075; horizontal speed is decreased by 0.075 per frame. Characters can reach a height of around 100 units (more than the height of the top platform on the far right of [[Temple]]) from the cannon's center when fired completely vertically. 19 units tall, 19 units wide, but may freely overlap platforms. A guide ring ~38.7 units in diameter aids in placement and aiming.

| [[File:SSBUStageBuilderCannon2.png|128px|center]] || Cannon (strong) || A larger cannon that shoots characters further. Launched characters deal 8% upon contact. Characters are launched at a speed of 5.9 units/frame (actual value 6.5 but characters aren't launched for a few frames). Physics are the same as the weak cannon and characters can reach a height of around 180 units (roughly from Temple's lowest platform to the middle platform on its far right) from the cannon's center when fired completely vertically. 24 units tall, 24 units wide, but may freely overlap platforms. A guide ring ~38.7 units in diameter aids in placement and aiming.

| [[File:SSBUStageBuilderPlatform.png|128px|center]] || Moving Platform (small) || Slowly moves from one point to the other, with an unlimited path. 30 units wide. Moves 0.2 units/frame. May overlap any object or platform, but endpoint must be at least 2 units away from start.

| [[File:SSBUStageBuilderPlatform2.png|128px|center]] || Moving Platform (large) || Over three times longer than the small one. 100 units wide. Moves 0.15 units/frame. May overlap any object or platform, but endpoint must be at least 10 units away from start.

| [[File:SSBUStageBuilderMagma.png|128px|center]] || Magma (thin) || Painted over platforms, and deals 10% damage to characters. It adds more weight depending on how much was drawn, even if the line overlaps with itself or other lava despite being redundant. Unlike [[Danger Zone]]s, it does not instantly KO a fighter if they have over 100% [[damage]]. 6 units thick.

| [[File:SSBUStageBuilderMagma2.png|128px|center]] || Magma (thick) || Works just like the thin one, but 10 units thick.

While Stage Builder was absent during the initial release of ''Ultimate'', on April 9th, 2019 an advertisement released by Nintendo discreetly revealed the Stage Builder icon on the menu, confirming that a Stage Builder mode was in development at the time of the advertisement's release.<ref>https://www.polygon.com/2019/4/9/18303962/super-smash-bros-ultimate-stage-builder-tease-leak</ref> A promotional video on April 16th confirmed the inclusion of Stage Builder in the version 3.0.0 update scheduled to release the following day.

The Stage Builder was greatly revamped since the {{forwiiu}} iteration. Besides the player-accessible layer, terrain can be placed in up to three additional decorative layers, with one in front of and two behind the playable layer. Various materials are accessible to be used. For the first time, it is possible to have platforms extend beyond the blast lines, which can be accomplished by the use of rails, allowing for [[walk off]] stages. Platforms can be drawn freehandedly, or using Square or Circle tools. Their material can be changed at the player's leisure with the Fill tool. Instead of sets of moving platforms, rails can be freely placed by the player in order to make any platform follow it. Rotation effects can also be added to platforms, and both the rotation and traveling of platforms across rails can be toggled on or off mid-battle by placing switches. Many objects can be changed with a properties menu, allowing tweaks such as adjusting rail speed or enabling terrain gravity. However, unlike in ''for Wii U'', custom stages cannot be used in [[Training Mode]] or [[Custom Smash]], both of which notably enable the player to modify the gameplay speed.

Unlike previous games, custom stages can support up to eight players by default, although that limit can drop back to four if the stage contains too many surfaces or objects, as shown by a weight gauge at the top of the screen. Going through a 4-Player stage with five or more players in Local Wireless will instead choose one of the game's normal stages.

When testing stages, the default characters for player and CPU are two {{SSBU|Mario}}s. However, as in ''for Wii U'', the player may change the default fighters via the pause menu when testing and are retained for all future uses of Stage Builder until the Stage Builder menu is exited.

Unlike the Stage Builder from ''Super Smash Bros. Brawl'' and ''for Wii U'', the backgrounds available to choose from are from stages in the game itself, being:

| [[File:SSBUStageBuilderTextureGrass.png|64px|center]] || Terrain || Acts as ground, ceiling, and walls. || Shape, material, dimensions, rotation, gravity, respawn, grabbable edges

| [[File:SSBUStageBuilderGear.png|64px|center]] || Gear || Rotates the attached terrain around the Gear as an axis. Rotates at a rate of <code>s/60</code> degrees per [[frame]], where '''s''' is speed. || Direction, range, speed, smooth reverse

| [[File:SSBUStageBuilderRail.png|64px|center]] || Rail || Causes terrain to travel on a selected path. Objects move along the path at a rate of <code>0.1s/24</code> [[unit]]s per frame, where '''s''' is speed. || Path, speed, starting location, smooth movement, hinged terrain, return after collision, return at edge, show rail

| [[File:SSBUStageBuilderSwitch.png|64px|center]] || Switch || When attacked, toggles gears and rails on the attached terrain. || None

| [[File:SSBUStageBuilderCannon01.png|64px|center]] || Cannon || Characters will be launched out of the cannon in the direction it faces, akin to Barrel Cannons used in {{SSB|Kongo Jungle}} and [[Kongo Falls]]. || Direction

| [[File:SSBUStageBuilderSpring01.png|64px|center]] || Spring || Characters will bounce upwards with a speed of <code>25g</code> units per frame, where '''g''' is that character's {{h1|gravity|Super Smash Bros. Ultimate gravity values}}. If up is held on the [[control stick]] or jump button is held, characters will be sent higher with a speed of <code>25g+1.75</code>. Unable to be rotated. Has no effect on physics terrain, unless it is attached, in which it will only forbid rotation. || None

| [[File:SSBUStageBuilderWarpZone.png|64px|center]] || Warp Zone || Characters will teleport to the paired Warp Zone. Has no effect on terrain, but items and projectiles that come into contact with it will also be teleported. Warp Zones will become inactive on a cooldown when a character enters them for a few seconds; this cooldown does not apply when items and projectiles are teleported. || None

| [[File:SSBUStageBuilderTextureBumper.png|64px|center]] || Bumper || Characters will be launched from the bumper, similarly to to the [[Bumper|item of the same name]]. Has no effect on terrain. || Rotation

| [[File:SSBUStageBuilderTextureLadder.png|64px|center]] || Ladder || Characters can climb ladder. Unable to be rotated, even if attached to physics terrain, causing it to stay upright. || Length

| [[File:SSBUStageBuilderTextureBombBlock.png|64px|center]] || Bomb Block || When attacked, it will explode, hitting nearby Bomb and Explosive Blocks. || Rotation, respawn, grabbable edges

| [[File:SSBUStageBuilderTextureExplosiveBlock.png|64px|center]] || Explosive Block || Will explode when nearby Bomb or Explosive Blocks explode. || Rotation, respawn, grabbable edges

| [[File:SSBUStageBuilderTextureWindArea.png|64px|center]] || Wind Area || Produces [[wind]] to push characters in a certain direction. Has no effect on terrain. Pushes with a speed of <code>0.02s</code> [[unit]]s per frame, where '''s''' is speed. Its effects can be reduced or negated by certain [[spirit]]s.|| Speed, direction, dimensions

;Gravity

:Acceleration downwards. Value is multiplied by 0.065. When multiple materials are part of the same object, the gravity of that object is based on the proportion that each material makes of that object, factoring in density and size.

::For example, an object made of paper with 16 grid tiles and steel with 4 grid tiles will have a combined density of 560 (<code>(16×10)+(4×100)=160+400</code>). Paper (with a gravity of 0.3) contributes 0.0<span style="text-decoration:overline;>857142</span> (<code>0.3×(160/560)=0.3×0.<span style="text-decoration:overline;>285714</span></code>) and steel (with a gravity of 1.0) contributes 0.<span style="text-decoration:overline;>714285</span> (<code>1.0×(400/560)=1.0×0.<span style="text-decoration:overline;>714285</span></code>), resulting in a gravity of 0.8. This can be simplified and generalized to the following <code>(a_1×d_1×g_1 + a_2×d_2×g_2 +...+ a_n×d_n×g_n)/(a_1×d_1 + a_2×d_2 +...+ a_n×d_n)</code>, where '''a''' is the area of the material occupies, '''d''' is the material's density, and '''g''' is the material's gravity.

:Mass per unit volume.

;Friction coefficient

:Resistance to being moved across other terrain. Gravity also affects this, however.

;Restitution

:Momentum conserved in rebounding objects; bounciness. A restitution of 1.0 will transfer 100% of the momentum back into the object, a value of 0.5 will transfer 50%, and so on. When an object collides with a surface, the highest restitution value is used. For example, sand (0.1), marble (0.3), and steel (0.5) will all rebound the same when colliding with a steel (0.5) or bouncy rubber (1.0) surface as those have equal or higher restitution values; colliding with a sand surface will result in the steel retaining more momentum than marble which retains more than sand.

''Ultimate''{{'}}s Stage Builder has a fairly large number of quirks, glitches and other issues, especially when compared to the Stage Builders in earlier games. These include:

*While testing stages, fighters idle poses will not occur until the fighter moves from their spawn position or uses an attack.

*Sometimes, Robin's Tomes and Levin Sword durabilities will not be correctly displayed on the UI next to the fighter icon while testing custom stages. Instead, the Levin Sword durability will always show as 0 and the Tomes will always appear to have maximum durability, however the durabilities function the same way they do in [[Versus Mode]].

*Ordinarily, if the "change fighters" feature is used, and a second controller is used, the second fighter can be controlled by a second player, and will be displayed as P2, with a blue battle UI as usual, while testing the stage. However, if "return to edit" is selected, and then test is selected again, the second controller will still control the second fighter as before, but they will now be displayed as a CPU, and will have a gray battle UI. The same can be done with P1 being controlled by the CPU while having a red "P1" tag.

*Although objects bouncing straight up off bouncy rubber return to the same height on average, their actual bounce height tends to fluctuate, with some terrains deviating slightly upwards every other bounce, and others deviating slightly downwards, returning to their original height on the next bounce. Oddly, when dropped from specific heights however, some materials actually end up gaining height over time, eventually despawning off the top of the stage. This is likely due to rounding errors not being corrected for.

*Springs are able to send low gravity characters higher than higher gravity characters. This is because while high gravity characters have higher speed, they lose it faster while low gravity have low speed but retain it for longer. This applies to all springs, but stronger springs exaggerate it&mdash;the strong springs can launch Jigglypuff (the lowest gravity character) noticeably higher than Fox (the highest gravity). This is less-so in ''Ultimate'' as the weak bounce's force results in a linear correlation between gravity and height, while the strong bounce is weak compared to prior games and causes characters with less than 0.0925 gravity (over half of the roster) being within 5 units of each other.

* In ''Brawl'', if the player tests a stage, [[self-destruct]]s, return to the Stage Builder menu before {{SSBB|Mario}} respawns and quickly tests it again, Mario will spawn on-stage briefly and then disappear with the camera scrolling to where he [[self-destruct]]ed then reappear on a [[revival platform]].

*Prior to version 1.1.3 of {{forwiiu}}, a regular Final Destination-like stage without any platforms filled with magma below (in a way that the magma seemingly covers the whole stage but doesn't hurt characters walking along the main ground) will cause all [[CPU]]s to indefinitely stand on place doing absolutely nothing, even at level 9, without even defending against attacks or recovering. This also works against [[amiibo]].<ref>[https://www.youtube.com/watch?v=-13F3hkM7XE]</ref>

*In ''for Wii U''{{'}}s Stage Builder, if the original {{SSB4MusicLink|Street Fighter|Ryu Stage Type A}} or {{SSB4MusicLink|Street Fighter|Ken Stage Type A}} songs from the {{uv|Street Fighter}} series are selected, the music will not change regardless of the match's present situation.

**Also in ''for Wii U''{{'}}'s Stage Builder, the volcano backdrop bears some sort of resemblance to the Volcanic Rim stage from Capcom's ''Street Fighter IV'' series.

*In ''for Wii U''{{'}}s Stage Builder, if start and select are pressed during testing (which will pause the game then go back to the Stage Builder menu if done correctly), nothing but the background music will be heard until the game is paused again.

**Most special moves will not gain distance against maximum speed horizontal wind over time, but certain moves like [[Wario Bike]] and [[Spinning Kong]] completely ignores wind.

*In ''Ultimate'', custom stages using the music tracks ''{{SSBUMusicLink|Other|MEGALOVANIA}}'' and ''{{SSBUMusicLink|Other|Floral Fury}}'' cannot be downloaded from Shared Content if the DLC entailing those tracks have not been purchased. Stages using music tracks from the Fighters' Passes will change the song to ''{{SSBUMusicLink|Super Smash Bros.|Battlefield}}''.
