Creating an event that doesnt spam at a specific value

how do i create an action to happen only once when a players hp hits a specific number.

Like 10 but only happen once when the hp is sitting on 10. I'm trying to create an explosion effect to happen once at 10 hp and turn off until hp hits 10 again after healed or damaged

Use a boolean that starts false but gets set to true right after the event happens - it will happen once and then stop happening since the conditional that checks the boolean has changed.

For bonus points you could reset the boolean at a later time to allow it to happen again (so for instance if you wanted the explosion effect to happen again later, but no sooner than a minute after the last one just change it back again with a Do after 60 seconds block).

that looks good but the problem that I am having is when the event is constantly triggered. Like when the player is sitting on 10 hp it'l keep triggering the event that happens at 10 hp instead of triggering only once.

What im trying to do is when a player's health hits or passes 10. To create an explosion effect. But if the player is on 10 hp for some reason I dont want it to keep creating that effect.

Try this idea (Explosion is a boolean, default = false), an extension of hectate's idea:

If HP = 10
  If < Not < Explosion > >
     Set Explosion to True
     [Explosion coding]

If player collides with an actor
   Set Explosion to False
   [Change HP accordingly]

i'll try that out, thanks,

Let me know how these suggestions work for you. I've been having a lot of trouble with this. I believe it's because I rely too much on the Always event, and less on the other events like boolean, comparison, etc. Still trying to figure it out.

The boolean "trick" works simply.

if hp==10 & boolean == False
   Do Stuff
   boolean = True

Then it'll only run once.
