When I've got a Model, and in another frame, it's moved upwards, the Null-Point is under the model. I want to know: when a ball hits the Null-Point, while the Model is in that frame, will the model be hit or not? Sorry, but it's difficult to explain that.

it depends on different factors - do you use polygon flag or not,how do you want to know if entity is hit(event_entity or maybe event_push)
The best way is to try and see the result

Thanks, I'll try... but what is polygon-flag?!

it enables precise polygon collision in A6

ah ok thx, since I've got a5 it doesn't interest me^^
