You can also use this like an ordinary system condition, using "Compare two conditions".
I think its more usefull, becase sometimes you cant use AND and OR conditions in a single condition block. Here is what I'm talking about:
Couple examples:
((Sprite.Angle > 0) & (Sprite.var1 <> 0)) | (Sprite.Var2 <>0) ? 1 : 0
There is two cases:
1. Sprite.Angle > 0 and Sprite.var1 <> 0
2. Sprite.Var2 <> 0
If any on this cases are true, it will return 1.
((Sprite.Var1 > 0) | (Sprite.Var2 > 0) | (Sprite.Var3 > 0)) & Sprite.Var4 = 0 ? "true" : "false"
If you got this one, then you got the idea, if not, then you should re-read this tutorial again! :)
I hope this text helped you to learn something new.
Thanks!
