How do I solve this healthbar issue?

Whenever I add health to the healthbar, it glitches and you can see the healthbar go over the max health. (for one frame.)

I'd like to know how to check to see if the value is going to add over max health, and if it does, set the number to a number which doesn't go over max health.

If health greater than health_max, set health to health_max.

Solved it.

For a single event,

On collision with heart - Set health to min(health+10,health_max)
