OK here is the tutorial =Click on Script menubar,then add an actor variable called "
canjump". On your players events, add a collision event (relating to the ground) with a script editor that says:
"
canjump = 1;" On your players keydown event (for whatever your jump button is)make the script say:
if(
canjump==1)
{
yvelocity = -8;
canjump=0;
}
