i already new that i just need it to be like a wall and not kill it or respawn it/teleport i need it to be like a wall

Use a purple more block with the Edit option “Run without screen refresh” checked to do the collision checking unseen and super-fast. You can use an entire layer/sprite for the walls and/or the ground. When the player moves, move that direction only and see if it the player sprite hit the wall sprite? If so, move back until not touching the wall and set that velocity to 0. This handles collisions in all directions and works with a velocity/gravity system.

Here is a work-in-progress demo of that type of system. It is a work in progress, but you can see this style of collision detection working for both the player and randomly sized enemy clones. Use the space to shoot enemies and move right to scroll. The ground level is changed randomly. Any time after the game has loaded, press the C button to spawn or re-spawn random floating blocks.
As you can see, this collision system works very well, even for the randomly moving enemies. Also not that the player actually consists of a ghosted rectangle that handles all the collision checking and an overlaid sprite that handles all the sprite costume animations.

I whipped up a simplified version of this collision system with complete script commentary so be sure to Look Inside. One difference between this one and the last one was that the previous project, although more complex, used squares against a rectangle to check collisions. This simpler version includes slope detection, giving you more options as far as how you go about drawing your floors, walls, and game maps in general. My other map consisted of 138 scrolling 20x20 tiles to create the ground. This project uses a simple vector image sprite for the walls, floors, etc that requires no scripts.

thank you locomule but i just want something simple and not too long t=

The ST made one of these. I suggest you look at it. It has comments inside to explain the programming, but if you have any more questions please ask me on my profile.

Hope this helps!

Ex:

when green flag clicked
forever
    
if <not <touching color [#000000] ?>> then 
  move (speed) steps
end

end

The color is the color of the wall

change y by (1)

Here! The legit script is…

when green flag clicked
forever
    
if <touching color [#ff0088] ?> then
move (-10) steps
    
end

end




Put this on the sprite that move in a maze for example. The touching color block should be the color of the barrier block. Sadly though, you can't add this color in the rest of the maze other then barrier blocks.

that wont work because what if you were on a y axis it would just make you fly directly upwards so no its not legit therfore does not work

You should also take into account that that code was ripped STRAIT from the ScratchTeam Maze Starter project. So the code is 100% official.

dude this strings in this forum is how to make a solid block not a maze dude

codeslayer00

if flag clicked if touching wall then bounce back

doublesnowcony

@codeslayer00 their is no script that bounces back -_- only a script “if on edge bounce”

superben100

ok

GAHHH THE NECROBUMPS ON THIS POST GAHHHHHHHH I CAN'T STAND IT.

Lol. But yeah, there are some pretty good answers here.

easy

when green flag clicked
forever
    
if <key [D v] pressed?> then
    
point in direction (90 v)
move (3) steps
if <touching color [#ff0000] ?> then
move (-3) steps
    
end

end

end
