Instance Variable set as variable

As the title says:

How do i set an instance variable with a other variable (as initial value).

Explanation:

I used the template Towerdefense and made it a lot bigger (only events). Now i want different waves, which i got worked out. The only thing still unsolved is the Enemy.Health instance. Which is 30 by default. Now i want to change it to another value but somehow i can only get it to work for the first 2 mobs, after that it uses the 30 instead of the 40 i wanted.

Setting it with an event didnt work out for me, because it or changes only the first 2 mobs or resets the hp every event-run to 40...

ps.

(if you want to see for yourself, look at MainEvent->Enemy Control->Wave 1)

pss.

When you spawn your enemy in the "enemy" group (event 19 I guess), spawn it and set its instance variable health value at that moment, according to the wave you are in.

To do so, you can set a global variable that you modify at each wave and set the value of the instances out of.

Thanks for the quick response, will try it out!

Sadly i cant find a way to set the initial value through a global/local variable. If you know any way to do it, please tell. (When i use on to set it every spawn, it resets all active instances to that value, meaning that the first spawn/instance was damaged and would be healed/reset his hp)

For now i use pick #th instance, to set the hp. (Every spawn would +1 to variable that the #th function would use). It's not very nice/clean/neat that way

Update:

The #th doesnt work correctly, trying to set 5th instance while 1creep died (setting all others instance number 1lower xD ), trying to workout a way for that.

Update2:

For some strange reason it suddenly works.... Just setting the value to a certain hp... the reason why? no idea xD

New link for updated project for the interested:

something like:

enemy on created

enemy set health : 30 + 10*TDWaveNumber

should make the health for

wave 0 - 30

wave 1 - 40

wave 2 - 50

etcetera..

For some reason i never got that to work. It simply ignored the fact ->On created.

But it works now, and i don't know why xD

Going to research why and how, want to know
