one jump.

[Sarsen]

Hi, sorry for my bad english, but a can't find decision. I create standart platformer on phaser, javascript. I use arcade physic.  After I pressed a jump button, my character jumps from the ground several times, while I release the button. I want its to jump once. I use this check to pressing:

if (keyJump.isDown && player.body.wasTouching.down)

Since update is checking for if keyjump.isDown, you can rather add a function when input is pressed.

Add this in create method:

keyJump.onDown.add(someJumpFunction, this);

When I use this method, more other things do not work as they should - animations and frames of characters(((((((((. Someone knows basic algorithms for behavior characters in platformer like super mario or sonic. Please!
