I don't know why we didn't do it like this…but here you go.

If my memory serves me correct, I'm sure we didn't do that to break scripts.

EH? It wouldn't break anything…

mormonman you should mention that this way its possible (if we manage it) to then use World3DToScreen for models.

Ya, but this function isn't quite working for me with models at the moment.
@Naike - it doesn't break anything.

wait, we are getting models soon? Sweet!

if so then that means we can get precise positions for things like doors and part-tile items, right?

I'm completely lost in whatever use this might have…

The Runetek5 engine uses 3D points to describe a certain point on the screen. This allows for the proper use of those points, instead of using the pixel offsets that are in the current TileToMSEx. The model class in the runescape client uses 3D points to describe where the vertices of the many model triangles are located.

Would TileToMSEx change? Or would all the stuff remain the same (based on the above post)

Not that I'm aware of.

This is PaintSmart telling me what the tiles are. I told it to make a perfect box with TileToMsEx and that is what I got back (was not from this thread, this is the current Reflection)

TileToMSEx is the same.

Would it fix this? Ideally one line, though it's not a big deal if it isnt.

Post the function for finding the boundaries.
