Question by erikzn · Oct 07, 2013 at 07:32 AM · c#2dcollisionsidescrollerhitpoints

Detecting collisions between objects from another c# script

Hi. I'm working on a game, where I have two characters on top of each other to control. (Play a prototype Here. Use Up/Down Arrow to jump, R to restart)

Right now, I'm kind of struggling with my HP/Life feature. The thing is, I have a static int = 3(Number of lives), which decreases by 1 if any of my characters collide. But, when both of them collide at the same time, it decreases by two, I only want it to decrease by one, so you have 3 HP total for both. I have separate control-scripts for each of the two characters, and detect collisions between the character and obstacles using OnCollisionEnter.

Anyone have know of any way to fix this?

The simplest solution i can think of is simply to wait for the end of frame and then only decrease health by 1 even if there were multiple collisions last time. Depending on the complexity of the project, this could be implemented many different ways (simplest would be to set some global or playerController flag to true, then in Update/LateUpdate decrease HP and reset the flag...
