Destroy object when Alpha Coefficient is X

[K1kk0z90]

Hi all!
I want an object to be destroyed if its Alpha-blending coeffcient is greater than 200. I have many instances of that object in my frame, and if I try to do it using "Compare 2 general values", it doesn't work properly, because (I think) the action "Destroy MyObject" does not refer to MyObject instance with Alpha-blending coefficient greater than 200.
I would need a "Compare to Alpha-blending coefficient" event. Is it possible to what I want without it?
Thank you in advanced for your help!

The easiest way would be simply setting an alterable value to the alpha blending coefficient (Always). Then, compare to the alterable value, which will probably select the object...

You can't use "compare two general values" when you have multiple instances of an object - it will always only compare the value of the newest instance.

You have to do what Looki suggested, which is to set an alterable value to the other variable, and then compare the alterable value.

It's the same if you want to use a more complicated expression.
For example, if you want to check if a specific instance is within a given distance of another object.
You first set an alterable value to the distance, and then in another event, you compare that alterable value.

Thank you both for your help, it works perfectly!
This tecnique is very smart, I'll remember it for the future.
