Thank you for playing ! I'm glad you had fun (^w^)
The idea of not having friendly collision may be great idea, but it's probably not possible the way I coded the units themselves for this project. (Basically I'm letting the engine manage most things collision related and I don't know if there is an easy way to ignore 'some' objects from collision). Thanks for the idea. I might try to manage the unit on a higher level for my next rts project so it's an useful idea . (^^)
That said, in case of mistakes, I do think there is still the "suppr" button that delete what is selected. It was mostly for debugging but it's always useful to have so I kinda let it in. ( There is not chatbox to confirm deletion tho, because they are hard to do (~"^w^)~)
Thanks again for playing (^w^)
