Four Swords Adventures
Pickup Clipping
An incredibly powerful technique that lets you clip a single Link into and through tiles.
Since its discovery it has replaced many glitch applications and opened up new significant sequence breaks.
Simplified Concept:
- Place two Links really close to a wall
- Move one Link slightly away from the wall
- Pick up the other Link still sitting next to the wall
- For one frame, the picked up Link overlaps with the wall
- Using a C-Formation, the Link can be pushed through and out of the wall
General Information
Due to the nature of how C-Formations accelerate Links, it is not possible to clip upwards.
Green acts as point of origin and therefore the position relative to the clipping Links is quite important.
Right and Down can bypass up to 2 tiles by default (and more in specific situations)
Left is more limited and can typically clip 1 tile.
Because precise positioning is required, setups are generally used.
These often involve cycling through all Links to snap their positions to the grid.
The most common ones are the sidehop into C-Right and moving left against a wall.
Links have different pickup behaviour:
Green picks up any other colour without delay
Red picks up Green with 1 frame delay and Blue & Purple without delay
Blue picks up Green & Red with 1 frame delay and Purple without delay
Purple picks up any other colour with 1 frame delay
Most setups use Blue picking up Purple (no delay) and left-side clips use Blue->Red (1 frame delay).
Default routine:
- Apply setup
- Press R and Start (same frame or 1 frame apart)
- Buffer C-Formation (& optionally Stick direction)
- (Time roll-input)
Common Pickup-Clip Types:
1-Tile C-Right
Fast to set up because Green's position doesn't need to be adjusted.
- Put a Link next to the wall you want to clip through
- Cycle through all Links once (this will position them neatly on the grid)
- Do a sidehop to the left (this will space Blue and Purple slightly apart)
- Hold Y and keep holding! (this let's you input formation commands and prevents you from moving)
- Tap right once to reunite and wait until Blue stands in position & Purple keeps walking in place
- Press X
- If the Links don't stack, tap right and press X again once they are in position
- Switch to Blue and tap right
- You may release Y now
This concludes the Setup.
Now press R and Pause on the same frame.
If you can see Purple being picked up, and held in front of Blue overlapping with the wall, buffer C-Right and unpause.
If Purple is on top of Blue, you paused too late.
If seemingly nothing happened, you either
- paused too early (R-Input didn't get through) but you can retry, or
- the Links aren't set up properly and Blue is trying to grab the wall (you can't tell the difference until after the fact)
2-Tile C-Right
Very similar to the 1-Tile Setup, but you will need to adjust Green's position by 1 tile to the right after Blue & Purple are in position.
Typically you either move Gree manually, and then for turning Blue you hold out the Sword to press Y without reuniting.
Alternatively, you can pick up Green with Red.
Make sure to not push Blue & Purple!
C-Down
They work analogously to C-Right, but come with the bonus of being able to retry the pickup if you paused too late by cycling through the Links once.
Left-Door (C-Left)
These are very specific and require individual setups.
Depending on the setup, you might need to time a roll.
Also keep in mind that for Blue picking up Red, you need to delay the pause by 1 frame.
In-depth Information:
To be able to be picked up, Links must be at least 1 unit (0.999023) apart.
One tile represents 16 units.
Given a simple number line with:
<-smaller | X=920 | bigger->
treat 920 as origin
origin = Links when cycled through, sitting next to right wall
921.000000:
slight natural clip into wall, regular stable right limit
can be achieved by simply walking towards the wall from point of origin
carrying something or diagonal movement will result in the decimals shifting
also clanking against the wall with the sword
919.000000:
left push setups use this and it is the lower limit of possible distance for a successful clip
918.999878 and smaller:
you are too far away from the right wall and clipping no longer is possible
Hop->C-Right Setup:
Blue: 919.500000
Purple: 920.530029 - 920.999512
Due to formation mechanics, Purple is oscillating and the final rest position depends on the X press timing
.530029 is the lowest value that I observed so far, which is just ~0.03 from not working anymore
