It's just not working for me, I may need to do some more tutorials to get my head around it all.
When you say "Enemy "on timer" Enemy Destroy", do you mean that the timer behaviour should in fact originate from the enemy and not the player?
So far my logic goes like this:
Enemy has line of sight? Yes? Then start Timer "playerDeath" for four seconds.
Enemy has line of sight? No? Then stop Timer "playerDeath".
Enemy, on Timer "playerDeath" elapsed? Player > Destroy
The game is actually doing the opposite to what I want it to do. If you loose line of sight for 4 seconds, you die. However, if you maintain constant line of sight, then you don't die!
