The first step in this health potion process will be to:
1. Make a Game Object or Monster and assign its Monster Flag to be a "Pickup/Powerup"
2. Next go to project settings and add a user variable and name it "healthPotion"
3. After that we will need to add this asm code to the Defined Scripts\Game\Pickup Script file. (In my script I used Monster #34. Also I am using both a Sprite HUD and Tile HUD in this example.) And you will probably need to change the HUD element # to match what your myHealth is assigned to.
Now we will need an input script to execute this Health Potion. Save this as an asm file and save it into your project. This example assumes your myHealth has 8 places. You can comment out or add to fit your game.
Now you will need to go into the input editor and assign this new script to a button of your choice and to "Main Game".
That should be enough to get you going! Comment if you need any help.
