Building foundation offset about openage

[zaxozhu]

As I understand, mouse cursor should be a center for a ground and a building sprite?

[TheJJ]

Mouse cursor placement is easy to fix, the main problem currently is the wrong center of the building texture hotspot, which does not equal the terrain tile grid placement. The calculation algorithm mentioned is likely to be wrong.

[zaxozhu]

You are right, algorithm needs to be fixed. However, I'm figured out how to place the ground properly.

I have a question. Is start_pos should be a west corner?

[TheJJ]

currently, start_pos is indeed the west corner of the building foundation. This can of course be adjusted to be the center of the mouse click. But this does not fix the offset error of the foundation and the building texture.

i think the game assets have the offset, we don't have to calc it

[TheJJ]

All graphical game assets have a hotspot, which is the center of the sprite.
The challenge is to position this hotspot correctly, in this case the center position of odd and even foundation sizes has to be found.

[franciscod]

but are we using the hotspot whe placing the graphic atm?

This bug is on every building.

i improved the alignment with most buildings here #143

however, castles, houses and some other buildings are still misaligned.

i think we might have to deal with this at texture-hotspot-delta-zombine level instead of at tile level
