Hi all,

Pretty strange problem here, I am reading in a TiledMap and parsing through the Layers then creating a Box2D box around the collision layers.

Problem is, it reads in the tiles fine and puts a box around them, but the 33rd box seems to just be ignored and then shifts every box infront of that along one.

It fits to the size of my camera fine but as I want the camera to be scrolling along the map this issues occurs. It seems to ignore everything 33rd tile.

Here's what it looks like.

Source code for reading in TiledMap:

This stood out to me: (just from quick scan-through)

Vector2 tileCentre = new Vector2((xPos / 32) + 0.5f, (yPos / 32) + 0.5f);

try making the /32 into /32f, to avoid integer division.

EDIT: might also be something with rounding, if the 32f screws it up more, or doesn't fix it, could also try
Math.floor(xPos / 32f) + 0.5f

Hi, thanks for your help, I tried forcing the float and that worked, the only issue is that it screwed the scaling.

Math.floor seemed to give the same result.

Could you post a screenshot of the "screwed scaling"?
