i need jump to script editor. i mean no "fly jump code"

but now i use paths to jumping lol

Make a variable and put it's value to 1 in beginning. Write that the actor can jump only when the variable's value is 1. When pressing [jump key] the variable's value must change to 0 and return to 1 when the actor retouchs the ground.
Now the actor must return to the ground before rejumping and it can't fly. I hope this helped you. (I'm not very good english speaker)

By the way: Are the paths good for jumping?

thanks. no. cuz when i jump towards to wall then my player goes throught of walls

You might be moving too fast for the collision detection to catch your jumper. increase the wall thickness, or slow the jump speed down.
