How do I add 15% to health pool

i i have two variables hp and max hp (10/100)

and when i click on 'rest' button hp should increase about 15% of maxhp

how do this?

You want something like

Set instance variable hp:

((maxhp * 0.15) + hp) > maxhp ? maxhp : (maxhp * 0.15) + hp

In human words, if 15% of maxhp + hp is grater than maxhp

set hp to maxhp

else set hp to 15% of maxhp + hp

Egozi i know what i must do when hp is less than 0 and more than maxhp -> set hp to maxhp and i receive 100/100

I have to translate into construct2

Set instance variable hp:

((maxhp * 0.15) + hp) > maxhp ? maxhp : (maxhp * 0.15) + hp

Ashley can you add a simple expression 'add x% of variable to other variable' ?

No, it should be easy already, just multiply it by 1.15 to add 15% for example.
