# Day 39
|
||||
|
||||
My `draw_bitmap` proc has been already setup to have the position specified
|
||||
from the assumped position of the center of the image.
|
||||
Its how I'm used to anchoring images by default so thats why I decided to go with it.
|
||||
|
||||
Casey however is using the corner however...
|
||||
and then is doing some offset alignment based on what he sees for the coordinates on GIMP..
|
||||
|
||||
I decided to hand calibrate the alignment by eye. Since I already have it centered on X, the `align_x` could
|
||||
stay zeroed for now and all I needed to do was align_y.
|
||||
|
||||
I also did not do the difference using a `tile_map_diff` like he did,
|
||||
I just returned a tile_map_position and switch the map coodinates to be signed
|
||||
(which tbh is fine I'll just adjust the math later when I need to).
|
||||
|
||||
I'm assuming it won't matter because the tile map setup we currently have is before he revamps the project with proper
|
||||
vector math data structures, and he might switch to signed coordinates for them in the stream.
