I am planning on making a small little shooter game and I want to make it so the player can't go past a certain wall.

I think this would work but I'm not sure

when green flag clicked
forever
if <touching [boundary] ?> then
move (-10) steps
end
end

here is a simple solution:

forever
if <key [right arrow v] pressed?> then
change x by (speed)
if <touching [boundary v]> then
change x by (() - (speed))
end
end
if <key [left arrow v] pressed?> then
change x by (() - (speed))
if <touching [boundary v]> then
change x by (() - (speed))
end
end

if <key [up arrow v] pressed?> then
change y by (speed)
if <touching [boundary v]> then
change y by (() - (speed))
end
end
if <key [down arrow v] pressed?> then
change y by (() - (speed))
if <touching [boundary v]> then
change y by (() - (speed))
end
end

lol forgot the closing tag
lol haha there was a typo in the scratchblocks code HAHAHAHAHA

this makes it so when a player moves a certain direction, it moves it and then checks if the player is in a wall. if it is, it moves the player backwards to where hopefully there was no wall

(i haven't actually tested yet but in theory it would work)

what is there some sort of edit limit because i'm a new scratcher or something ugh… well by “typo” i mean there was a missing “end”

or I could've just done this

when green flag clicked
forever
if <touching [boundary] ?> then
change y by (-5)
end
end

and that would do it just fine but thanks for your suggestion

well you never told me which sides the player would be able to hit the boundary, so i had nought but to assume that the player could hit it on all sides

wow, that was a fast reply and the cat is going up/down. But I guess I'll try your method since mine is letting the cat go through the boundaries and then he's just gliding out of them.

say [thanks for the help!]
think [well now it's time to code (or maybe go to sleep?)]

here is the moving script i'm using

when green flag clicked
forever
if <key [a] pressed?> then
change x by (left)
end
if <key [d] pressed?> then
change x by (right)
end
if <key [w] pressed?> then
change y by (up)
end
if <key [s] pressed?> then
change y by (down)
end

im new to scratch do I put all this into the sprite or background?


I figured it out

Here is one way to do this:

when @greenFlag clicked
go to x: [...] y: [...]
forever 
set rotation style [ don't rotate v]
... // movement script goes here 
if <touching (boundary v)?>then 
point towards (boundary v)
move [the amount away you want your sprite to move] steps
end
end

Super efficient script made by griffpatch, better than anything anyone else came up with here:

define Collision
repeat until <not <touching [wall v] ?>>
move (-1) steps
end

when flag clicked
forever
movement
Collision
end

someone can walk to the wall. press aginst it and then look away and theyd pass it trough it
