So I wanted to do a pac man maze and at first I thought to draw over one with a tilemap and then give the solid behavior to the walls but it's quite a pita since it's hard to keep the same proportions of the original. Then I found this tutorial for Unity where he adds multiple collision boxes on the same maze. How would you do it on C2?
You can do the same in Construct 2. You create a sprite for colision box, set its initial visibility to invisible and position like in teh Unity tutorial.
That said, I, myself, would go for a tileset approach. I believe its better.
