I am making a platformer and I want wall jumping to be in it, but I don't know how to make it! any tips?

If you know how to make a regular platformer, then wall jumping is an extension that comes in two parts: Detecting a wall and activating a walljump.

Detecting a wall:



When you move horizontally, touching the level means touching a wall (unless there's slopes, then it's a bit more advanced). If you're touching a wall, you can walljump. So inside your wall detecting script add a check to see if the player is jumping, and which direction the walljump should go.

Activating a walljump:



This part is far easier and requires no explanation.

You may notice that this method only works if you're pushing into the wall. If you're not, it won't jump. You can separate the walljump detection into its own script where it moves left and right one pixel to check if its next to a wall.

Thank you SOOO much!

But what do I put under Define uncollide?

What are xvel and yvel?

Is the sprite: Level, my ground sprite?
