Gravity Help

So im trying to implement a feature where you can toggle gravity on the player for a few seconds, but when i go to test it unity completely freezes and im not sure what ive done wrong. heres the code snippet

private void Update()
{
while (Input.GetButton("Jump"))
{
ToggleGravity();
}
}
void ToggleGravity()
{
if (GravCharge > 0)
{
rb.useGravity = false;
GravCharge -= (1F / GravCharge_use) * Time.deltaTime;
}
else
{
rb.useGravity = true;
}
}

 

first of why is you Update void private? it's just void Update(){ } then I think the issue comes from your while loop, try

Code (CSharp):

1. if(input.GetKey(KeyCode.YourButton))
2. {
3.  
4. }

 

thank you! that stopped the crashes but unfortunately now it wont turn off >.< dunno why i didnt think to change that to an if instead of while

 

what do you mean by it wont turn off? can you show your entire class?
