+== Collision data ==
+The collision of an object is defined by a set of polygons combined together.
+
+The polygons are represented using the vertices of each polygon, and those vertices are represented using their coordinates according to the in game image resolution.

+=== Polygon data ===
+The data of a polygon starts with the number of vertices. The coordinates of each vertice are then stored as float32 values on an allocated 0x40 byte section.
+
+If the coordinates don't fill the 0x40 byte section, the remaining data is set to null bytes.
