Hello guys oh gosh i tried so hard to figure out this and i failed hard :D.
So here is what i want to do , i want when i press a key for example lets say
spacebar my character will play an animation but for this time i want to disable
the movement and the jumb ability of him.
The help i need is
Key SHIELD
*When u press this key disable all other movement and jumb functions and do “that”.
or
*When u are standing still and u press this key then do “that”
I appreciate for any help in advance and happy game creations 
Well make it when you press the key to deactivate the character:
Key (down) -> (off) Enable
|__> (start) Animation (play) -> Timer [delay 0, repeat forever]-> (stop) All other animations
Make it when the Animation ends to reset the Timer
Almost sure this works (i just woke up)
ohhh thx pixelPizza , something works !! the only problem now is to figure out how
to stop using it in the air 
.Also i see that i can abuse it as long as i hold the bottun
i am immune ;/
Make it to where it casts a ray under the player, and if the ray hits, you can use it
hmm i cant understand how the ray works 
i am not familiar with it. can u check

Raycast sends this invisible line a certain distance, and if it hits something, it triggers hit but if not it triggers miss
