Once i tried making WarCraft 3 maps with Map Maker (later MM), very similar to Construct 2 (later C2).
In MM the event sheet is separated in 3 parts:
1. Event or trigger - this must happen to continue, for ex. unit enter region1; unit1 is attached
2. Condition - here are AND and OR logic conditions, for ex. unit is owned by Blue Player; Damage done > 10
3. Action - if it is triggered and all/or some conditions are met, this will happen, for ex. destroy triggering unit; subtract (damage done) from owner of the attached unit.
I want to concentrate on the "Action" part. With this detection of ANY triggering unit i can do something to it. By comparison, now in construct two i have to make as many events as there are units and in all of them to perform the same actions.
I have searched for this feature with search engine on Scirra, but nothing came up. I don't have paid version so maybe on the paid there is this feature. If not, i like to hear your thoughts about this, and maybe have this feature in upcoming releases.
