One-Way Wall Bypass (SMM)

The **One-Way Wall Bypass** is an intermediate trick used in *Super Mario Maker*. This trick allows Mario to clip through a One-Way Wall which is normally not possible.

## Variations

### Big Mario

Note: This only works in *Super Mario Maker* *<br>* When Big Mario spawns in a 1 block wide gap he is large enough to be considered behind the one-way wall which allows him to pass through.

### Boot Clip

Note: The Giant Boot method only works on levels created before version ?

Dismounting a boot as Super Mario or higher will allow Mario to clip through a one-way wall if executed near ground blocks while holding forward. It is also possible to to bring the boot if Mario does a quick jump after landing in the boot as Super Mario.

Alternatively, jumping into a giant boot that is on a Semisolid directly underneath a one-way wall will allow Mario to clip through it when he enters the boot. It is also possible to go through ground blocks with this method.

### Bowser / Sledge Bro Stun

Note: This only works in *Super Mario Maker* *<br>* In the Super Mario Bros. 3 game style, after Bowser stuns Mario there is a brief moment where he can clip through an upside down one-way wall. Sledge Bros. can clip Mario through in all 4 game styles. This will only work if Mario is Super Mario or higher.

### Clown Car

By jumping into a Clown Car that is partially inside a one-way wall, Mario is able to pass through it. The reason for this is because the Clown Car is already considered to be behind the One-Way Wall when Mario gets in it. This can also be performed by doing a Partial Wall Clip while coming from behind the one-way wall (in *Super Mario Maker 2*, partial wall clips can't be done from underneath, so it has to be done from above).

Note: This only works in *Super Mario Maker* *<br>* By dismounting the Clown Car, Mario can also partially clip inside of the one-way walls.

### Downward Facing One-Way on a Semisolid

Note: This only works in *Super Mario Maker* *<br>* If a downward facing one-way is on a Semisolid with Munchers placed next to it (on top of the Semisolid), it is possible to duck jump and avoid the Munchers by a few pixels, and then ground pound to land on the platform. This can also be performed underwater by swimming close to the Munchers. An easier variation can be done with Thwomps or Grinders.

### Duck Jump

Note: This only works in *Super Mario Maker* *<br>* If Mario is Super Mario or higher, he is able to start ducking and jump before his hitbox is lower than the one-way walls allowing him to perform a duck jump when one-ways walls are at head level. (It is also possible to bypass a hidden block with this method)

### Ducking Wall Jump

Note: This only works in *Super Mario Maker* *<br>* If Super Mario or higher performs a wall jump near a Semisolid Platform after duck jumping he is able to clip through a one-way wall.

### Falling Block

Note: This only works in *Super Mario Maker* *<br>* If a block falls at the correct angle it will push Mario into the one-way wall to try to crush him. However, because one-way walls are not a complete wall Mario will simply pass through it instead of being crushed. It is also possible to only be partially clipped through if the block does not push Mario far enough. This can also be done with a falling Muncher, although Mario will take damage unless he is invincible.

This will only work if the one-way wall is facing right.

### Ground Blocks

Note: This is partially patched on levels created after version ? of Super Mario Maker

By coming from the back side of a right-facing one-way wall, Mario will still be considered behind the wall allowing him to walk directly through it. While this does not normally work on new levels, interestingly it is still possible if a one-way wall is positioned on the 8th or 128th X coordinate.

### Note Block Clip

Note: This is only possible before version ?

If Mario is standing next to a right-facing one-way wall he can be pushed through it with a Note Block. This method was globally patched, however, interestingly enough this is still possible if the one-way wall is placed on the 8th or 128th X coordinate.

### Partial Clip

Note: This only works in *Super Mario Maker* *<br>* Mario is able to partially clip inside of a one-way wall if he starts from in front of it and jumps between it and solid ground.

### Power-up Attack Clip

Note: This only works in *Super Mario Maker* *<br>* When jumping from a crouched position, shooting a fireball or doing a tail/cape spin will cause Mario to stand up for a brief moment. If done at the right time while also holding forward against solid ground, Mario will be able to clip through the one-way wall.

### Power-up Collect

Note: The skidding method is patched on levels created after version ? of Super Mario Maker <br> Note: The near-ground method only works by jumping into it precisely after version ? *<br> Note: The Jumping Into method has been patched after version 1.0.0 of Super Mario Maker 2 <br>*

Collecting a power-up, other than a Mystery Mushroom, will allow Mario to clip through a one-way wall if executed near solid ground while holding a direction by jumping at the correct time. An easier version can also be done by jumping into the power-up from below. This is also possible to do without jumping by delaying the time it takes for Mario to start crouching, such as by skidding.

### Semi-Solid

Note: This only works in *Super Mario Maker* *<br>* By coming from the back side of a one-way wall, Mario will still be considered behind the wall allowing him to walk directly through it.

### Spikes

Note: This only works in *Super Mario Maker* *<br>* Because spikes are a few pixels smaller than one-ways, it is possible for Mario to bypass one-way walls by jumping just far enough past the spikes enough for him to not hit them. Mario can also perform a Partial Wall Clip and pass through a one-way wall as long as the block directly touching it is a spike or an empty space.

### Spring Clip

Note: The bouncing springs method is partially patched on levels created after version 1.47 of Super Mario Maker

If a spring is bouncing upwards on top of another spring it is able to clip Mario through a one-way wall if he jumps on it at the correct time. It is also possible to go through ground blocks with this method.

Note: This only works in *Super Mario Maker* *<br>* Alternatively, if Super Mario or higher duck jumps into a sideways spring he is able to clip through a downward facing one-way wall. This can also be done with Small Mario if is riding on Yoshi

### Underwater Clip

Note: This only works in *Super Mario Maker* *<br>* If Mario is on a Semisolid directly underneath a one-way wall as Super Mario or higher, forcing Mario to uncrouch by swimming will clip Mario through it.

### Vine Clip

By performing a vine clip Mario is able to clip through solid ground, including one-way walls. While cliping insde one-ways is not possible in *Super Mario Maker 2*, and that it can not be used to go inside ground blocks anymore, it can still be used to clip through ground blocks.

### Vine Partial Wall Clip

If Super Mario is climbing a vine that is directly beside a wall he is able to partially clip into it by climbing towards it. This allows Mario to get far enough forward to be considered behind the one-way wall allowing him to pass through it.

This is also possible as Small Mario when in the Super Mario Bros. 3 and Super Mario Bros. game styles.

### Yoshi Dismount

Dismounting a Yoshi as Super Mario or higher will allow Mario to clip through a one-way wall if executed near ground blocks while holding forward.

### Yoshi Mount

Note: This only works on levels created before version ?

Placing a Yoshi part way through the one-way wall will allow Mario to pass through it by remounting Yoshi. This will only work if the one-way wall is facing right and in the New Super Mario Bros. U game style.

### Yoshi/Clown Car

This trick will only work if the player dismounts the Clown Car using any of the shoulder buttons.

## Object Bypass

In addition to Mario being able to bypass a One-Way Wall, it is also possible for an *object* to bypass it.

### Boot

Mario is able to bring a boot through an upside down one-way wall if he does a quick jump after landing in the boot as Super Mario or higher. This is not required in *Super Mario Maker 2* as the hitbox of Super Mario inside a boot is now what it looks like (~2 blocks instead of 1), so Mario is always considered "above" the one-way wall.

Note: This only works in *Super Mario Maker*
It is also possible to do boot hops against a wall as Super Mario or higher and ditch it on either the right side or left side of an upside down one-way wall to go through it.

Note: This only works on levels created before version 1.1.0 <br>In *Super Mario Maker 2* this is not possible anymore due to the hitbox of Super Mario in a boot that is ~2 blocks high instead of 1 but it was possible in a slightly different way, as Small Mario in a boot while still doing boot hops against the wall on either side of the upside down one-way wall and jumping to collect a powerup to grow higher (Super Mario or higher) in a way to get past the upside down one-way during the jump's up momentum will make Mario go through it. This is harder in a 1 block high space as the boot hops makes it hard to get the required jump's up momentum.

### Koopa Troopa

Jumping on a Koopa Troopa that is directly beside a vertical one-way wall will send the Beach Koopa flying through it. This is only possible in the Super Mario World game style.

### Note Block

Note: This only works before version ?

If a Note Block gets pushed downwards it is able to clip a Bowser through a sideways one-way wall. It is currently unknown is this worked with other enemies. As of version ? this trick no longer works, meaning that any level that required it is impossible.

### Spawning From a Pipe

If Mario jumps on a giant enemy as it is spawning from a pipe it is possible to clip it through an adjacent one-way wall.

### Thrown Items

P Switches, Springs and POW Blocks can be thrown through a one-way wall by default if Mario is standing next to it. Yoshi on the other hand is only able to spit objects through if he is standing a block away from the one-way-wall.

Other objects, such as a shell, will rebound off.

### Up Thrown Items

If Super Mario duck jumps into an upside down one-way wall he is able to clip it through by doing an up throw.

### Yoshi

If a Yoshi is stuck to a one-way wall, Mario is able to take him through by landing on Yoshi while facing the same direction and then immediately turning around the opposite direction on the next frame. (This will not work if a Yoshi is simply placed beside a one-way wall and instead must have some horizontal speed when going into it.)

Alternatively, if a Yoshi is in the air landing on him after doing a Spin Jump as Super Mario or higher will cause him to slightly jump upwards allowing him to pass through a downward facing one-way wall. This still works in *Super Mario Maker 2*.
