How do I make a health bar?

I wanted to make Dishonored-style health bar and decicded just to separate it into different frames and change them as players health goes down or up. But for some unknown reason it doesn't work. I tried lots of ways and none of them work as I want. I just have no idea at all. I'm completely new to construct.

What I’ve done similar to what you mentioned is create a health bar sprite of 3 frames. Frame 0 Has 3 Full Red Hearts. Frame 1 has 2 full red hearts. Frame 2 has 1 and frame 3 has blank or no hearts.

Then set Frame Speed to 0 so the animation doesn’t cycle through.

In the Event Sheet, I created a Global Variable calling it Health.

An Event was created that when I got attacked or set to is Flashing I subtracted 1 from the Health Global variable.

The next event I set the Compare Value.

If (Global variable) Health = 3 - Add action: Set the Health sprite Frame to 0

Then created repeating events:

If Health = 2 set Health sprite Frame to 1

Health = 1 set sprite frame to 2

Health = 0 set sprite frame to 3

If Health = 0 add action: Restart Layout or whatever you intend to do.

My problem is that I'm a free user and I can't have lots of events. I need to save as much events as possible. Sure it would be MUCH easier but I'll lose lots of events that's for sure. Is there any other way?

This might work:

Add an Event: Is Player on Collision with another object (Enemy) (Just using Player and Enemy as Example Objects you can create)

Add a Sub Event: Health (Animation Sprite you created) - Compare Frame < (less than) 4 frames (or whatever number of frames you have.

Add Action: Health sprite: Set Frame - ok type in the white field for Frame number: Health.AnimationFrame +1

(I said Health as that is the name I gave the health bar sprite. If you have it a different name, you have to use that. It should auto appear as you type same with AnimationFrame.)

One Event. Try it. Good luck.
