if(can_jump==1) ?

[Romol]

Why beside I do not work the action of one jump?
that it is necessary to do?

make a varible called jump
on the key down you want to have the player jump put

Code: Select all

if(jump == 1)//if the varible jump equals 1 and only one do the things in the brackets {}
{
yvelocity -= 10;//change  the yveloicty to make the player go up
jump = 0;//change the varible so the player can't jump twice
}

then when you collide with the topside of "ground" put

Code: Select all

jump = 1;//resets the jump varible to jump again
