you know, when that variable is 0 the game ends (sorry, i’m spanish and its hard to talk in english)
If in the stats screen, you can use the
*stat_chart percent (variable)
to display a bar.
For ending the game when a variable reaches zero, you can use
*gosub commands to check if it’s zero or not, and use it to go to a scene where the game ends.
You can also use
*if statements to check if the variable has reached zero, but the code will have to be copy-pasted to every instance where the variable has decreased.
*stat_chart percent health HP
And when you want the game ends.
*if health <= 0 game over tadaaa
