Issue with Timer not restarting

Hi,

I'm working on a game where the main character is able to transform into different animals forms. I'm using a boolean to detect their current form and was trying to set up a timer so that if they go underwater when not in the 'fish' form they drown, but it only works when they first enter the water. If they transform into the fish form and back again while underwater the timer doesn't restart. How do I fix this?

I would do this with 2 variables to detect 'under water' and 'fish'.

When you collide with the water surface, set 'under water' to true and of course when you exit / not overlapping water set it to false.

If under water and not fish (and timer is not running) : start timer

On timer : destroy

If 'fish' : stop timer

Many thanks, lionz.
