How do you draw your health as an image in Game Maker?
Answer:
First, in the Create Event of your character's object, make a variable to represent health. You can use drag-and-drop or use code. I'll use code. Make a variable like the one below. (The number doesn't really matter for now. It can be updated and tweaked as you work on your game.)
| health=3; |
You can go ahead and make a sprite to represent your health. It can be anything you want and whatever size you want. For this example, I'm making a circle that is 32x32 pixels to represent my health.
Now, make a new object. Name it whatever you want. Ours will be called objHealthDisplay. In this object, add a Draw Event. This time we want the action for this event to be execute a piece of code. In the code box, we put this code:
|
if (objMyCharacter.health==3) { draw_sprite(sprHealth,0,32,32); draw_sprite(sprHealth,0,64,32); draw_sprite(sprHealth,0,96,32); } else if (objMyCharacter.health==2) { draw_sprite(sprHealth,0,32,32); draw_sprite(sprHealth,0,64,32); } else if (objMyCharacter.health==1) { draw_sprite(sprHealth,0,32,32); } |
Let's break it down!
- objMyCharacter is object name of my main character. objMyCharacter has a variable called health (we made it in the above step) When I do objMyCharacter.health, it gets the value of the health variable. So in the draw of the object objHealthDisplay, we want to ask what is the health of the main character.
- Based on the health of the main character, we want to draw our health sprite. (sprHealth in this case)
- If we have 3 health, draw 3 health sprites. If we have 2 health, draw two, and so on and so forth.
Now this code is just one of the ways to do this. That's the great thing about coding in general: once you get the basics, you can try other ways to do the same thing. As you learn, you will find your own unique way to code things!
