damage help

[ban885]

hey guys, im currently working on a game and im having an issue calculating some damage, like i want to deal a percentage hp damage but i have no clue how to do this, i've tried like "hp-=.25*hp" i've looked almost everywhere but here. some if i could get some assistance that would be great thanks .

try

hp*=0.75

you have '+=' , '-=' ... but also '/=' and '*=' when you manipulate variable ...
have fun

You could do the calculation like this

hp -= hp / 100 * 50;

This subtracts 50% from the hp value.

EDIT* Actually can you give us more context on what happens in your event? I don't think your calculation is the problem.

i don't know it just seems off, like doing hp*=0.75 puts the hp at exactly 75 hp. like it doesn't feel right. sorry its hard to explain... um so like if you ever play league of legends. they have base hp damage like doing 2% of a character hp. but instead i feel like its just taking the damage from the current hp, instead of the whole thing.

You need to keep track of their max hp. So it'd be something like:

hp -= max_hp * 0.02;  // Take 2% damage
