Void OnTriggerEnter not working

Questions & Answers
1

I have a chest with a boxcollider2D that is set to: ‘is trigger’, and this script:

void OnTriggerEnter() {

	if (Input.GetKey(KeyCode.UpArrow)) {

		chest.SetBool ("open", true);

Also on the chest is an animator with a parameter called ‘open’, that when set to true plays the chest opening animation.
But when my character walks in front of the chest and i press the ‘up arrow’, nothing happens!
Please help!

“But when my character walks in front of the chest and i press the ‘up arrow’, nothing happens!”

That’s because OnTriggerEnter fires in only the single frame in which you enter the trigger. You’d need to be holding dosn the up key, then walk in front of the chest for your code to work. Alternatively, use OnTriggerStay instead of OnTriggerEnter.
