Custom Blocks causing lag

yaboiyusuf321

Hello, I have a problem with custom blocks. I am making a ray-caster and am trying to make a ray-cast script. However, when I make a custom block to do a loop, it lags. There are no wait blocks or anything, just a repeat until loop and a repeat block. It is run without screen refresh. let me show you a picture.

.
It shows:

define raycast create
point in direction ([direction v] of [player v])
turn ccw (60) degrees
delete (all v) of [list v]
set [distance v] to (0)
repeat (120)
go to [player v]
turn cw (1) degrees
create clone of [myself v]
when I receive [raycast v]
clear
raycast create

define move
repeat until <touching [level v]?>
move (1) steps
change [distance v] by (1)
when I start as a clone
move
add (distance) to [distances in view v]
stamp
delete this clone

So those are the scripts, nothing holding it up, run without screen refresh and it still lags badly. If you want, I'll give you a link here. Thanks in advance!

when I receive [i see this v]
set [my brain v] to [blown up]

So you need to share the project, not scripts out of context.

It is shared, it's at the bottom of my post

Oh and also everyone it's in the “raycast” sprite

I am not entirely sure how the funtions(custom blocks) work on scratch. In some cases when you put a repeat it will not lag, but in most cases when you put a repeat loop the script will lag. Here is a possible solution.

define raycast create
point towards [player]
turn ccw (60) degrees
delete (all) of [distances in view]
set [distance] to [0]
set [CloneDirection] to [0]
repeat (120)
change [CloneDirection] by (1)
create clone of [myself]
end

when I start as a clone
go to [player]
turn cw (CloneDirection) degrees
Move
add (distances) to [distances in view
stamp]
delete this clone

You need to make sure that the Clone Direction Variable is “For This Sprite Only”. I believe that should work.

It didn't seem to work but thanks anyways for making my code simpler!

Use less angles. In the repeat 120 make it repeat 60 then turn 2 degrees

Edit your “raycast create” custom block to “run without screen refresh” to create all the clones at once and all the lag will disappear.

Hey @Scratch-Minion! I turned “run without screen refresh” off for testing and have turned it back on, yet it still causes lag. The problem for me is that the “run without screen refresh” is causing lag in the first place and it can't be the clones because even without them it still lags. Thanks for the help tho!

Thank you for all your help!
