Introduction

Tiles can take on more than just square shapes or blank areas. You can define different kinds of boxes, slopes (triangles) or even arbitrary polygons.

Setting the Collision Shape

Suppose that we want to set the collision shape for the tile selected below. It's a sloped tile at about a 60 degree grade.

1) To set the collision shape, go over to the Collision Bounds window, scroll using the scroll bars to find the shape you need, and click on it.

2) Save your Tileset to confirm the changes.

Custom Collision Shapes

Sometimes you will need a custom collision shape for a tile that isn't reflected in any of the standard shapes we provide.

If this is the case, you can define a Custom Collision Shape by clicking on the + button. You can create either a Box or a Polygon.

Box Shapes

X and Y dictate the relative position of the box, in case you want it to be shifted off the origin (0,0).

All values are in percentages (0 - 100 inclusive). We do this, so that you don't have to worry about how big the tiles are.

Polygon Shapes

Create a Polygon by defining points and setting their x,y values, either through the table or through drag and drop. A polygon must have 3 or more points but no more than 12.

I am working with the example created in the crash courses to evaluate Stencyl.

The provided tiles I used have a square collision shape. I added some platforms and lowered the gravity. You can jump to them and they usually act as you'd expect.

Unfortunately It's possible for the player actor to be trapped in the tiles that should be
solid and there does not seem to be a way to escape.
What conditions do tiles not work and why?
I am thinking maybe they need to be smaller than the actor or something like that.

Any plans in the future to resolve the convex polygons issue? I am making a top down game and have L shaped "walls" that are bugging out because I am using Convex Polygons...

Same problem here, but only with the rpg style scenes. To the platformers i dont have the problem

I just happened across Stencyl last night and I've had no problems with using tilesets.

You most likely did not tell your Player actor's collision group to collide with Tiles as well as Actors.

Same here. I'm assuming it's a bug. For the time being, I've created actors with invisible frames and set them as 'walls', placing them over the tiles and using those to provide collision. I hope this gets fixed soon, as filling the scene with actors is just going to make things unnecessarily slow.

This doesn't work for me I have to get each tile I want and turn them into to actors for them to have collision. I think I got a broken stencyl and it's driving me mad.
