Simple Jump

I am making a mario style sidescroller and I have made a button for the player to jump but he just keeps going up until let go of the button. I just want the player to have limited jump time so he goes up for a second and comes down ( smoothly if possible).

You want to use the change attribute > self.motion.linear.y to say about 200. Then have an accelerate down (270) behavior for gravity.

If you have more questions, ask. My templates below might be of help to you.

If I hold down my finger he still just goes up but slower

Basically, you need an attribute on your actor, let's call it "Grounded".
Whenever your actor collides with a ground object and his Self.Motion.Linear.Y = 0, he has landed so set Grounded to true.

Then when you press your jump key, if Grounded = true, and his Self.Motion.Linear.Y is still 0, you can jump - so set Self.Motion.Linear.Y to something like 200 to 400 and set Grounded to false.

Then either have a constant downward accelerate as jb15 suggests, or set the Gravity attribute of the Scene.

It still isn't working. I used the mario controls video to create the left and right controls if that would effect my failure.
