How to make a sprite not go through walls?

Eclipsed6

Alright, I'm making a platformer and I'm trying to make my main sprite wall jump and not go through walls. Are there any simple scripts that allow the sprite to wall jump and detect walls?

Option 1:
You can use this block:

<touching color [#fffff] ?>

if your not using different color walls or if you are using different colors then:

<touching [Walls v] ?>

Option 2:
Make 4 sprites:
Top sensor
Bottom sensor
Left sensor
Right sensor
then make them all be around the player
then in each sensor:

forever
if <touching [(sensor name) v] ?> then
    
end
end

It worked!

Although, I just have one more question, would it be the same script if the platform is inclined or bumpy?

Yes,because of the bottom sensor!

This is the best wall detection script, in my opinion:

if <touching [the side of the wall v] ?> then
    
set [variable to control x velocity v] to (((0) - (variable to control x velocity)) * (1.5))
end

Hope it helps!

No No No, this is how u do it with wall sensors on either sides of a sprite:

when green flag clicked
forever
    
set [LastX v] to [ (x position)]
set [LastY v] to [ (y position)]

if <touching [Wall v] ?> then
go to x: (LastX) y: (LastY)

    
end


end

You will of course have to have the proper movement of the Sprite inside the script swell, I think it works!

change y by (the amount of steps the character goes up, multiplied by negative 1)
end

end

end

If the wall is on the right side of the screen, you would put this for not going through walls:

when green flag clicked
forever
    
if <touching [wall v] ?> then
change x by (any negative number below -9)
    
end

end

For wall jump, assuming the wall is 100 y and 50 x, and at x:0 and y:0, and the center is the middle left side, and the character is at x:-20 y:-50(right foot is his center):

glide (less than 1) secs to x: (-10) y: (80)
glide (less than 0.6) secs to x: (80) y: (80)
glide (same number as the first glide block) secs to x: (80) y: (-50)

I haven't tested it. Tell me if it works or doesn't.

Suggest you creste your own topic rather than necroposting. Share what you have so far and describe the problem.

While you're on here why not close this topic.

Here's how I do it:

when green flag clicked
forever
if <key [ d] pressed?> then
change x by (3)
if <touching color [#664303] ?> then
change x by (-3)
end
end
end

the color is used as the basic walls for the game. it's not a separate sprite but part of the background:D

Guys, don't necropost. This topic is from 2015.
