LÖVE

Hi,

I am building a top-down game. I used Tiled to create the map with collision polygons, exported to Lua, loaded & displayed it with STI, and built a player & displayed it. I am using LÖVE2D physics; I told STI about this. I recently made the map's object layer collidable and started displaying the rocks and player with the STI callbacks.

There is now a bunch of white lines in the top left corner of the map; they are in the first tile. I attached a screen capture image.

I am baffled. Has anyone seen this behaviour before? Any clues to guide me in my investigation?

Thank you.

I hesitated because most of the source code is not in Lua. Beware!

Is there an objects layer in Tiled? Maybe STI is rendering one of those.

Yes there is an object layer: the rocks are on that layer and you can see one in the screen capture image. The rocks are drawn where I expect them.

The sketchy library showed me that all the rock collision "boxes" are in the middle of the screen. The bulldozer's collision box is offset and moves with the bulldozer (same scale); it show only the pointer triangle. Collisions are otherwise working (well, only for the object layer and the dynamically created player layer).

I will go read the Drawing Physics Collisions tutorial. I only recently found it.

After that, I need to find a tutorial on collisions for the tile layer.
