Tyler, in discord: "@Kaztalek and others who were thinking there were a couple speed vectors being added were basically spot on. When testing for wall collisions on Bob-ombs, the game first adds the speed to the current position and uses that point in the collision calculations. The algorithm pushes the bob-omb outward from the wall if a collision occurs, so if it's already against the wall it effectively adds the component of the bobomb's speed that's tangent to the wall. Regardless of whether a collision occurs or not, the Bob-omb's position is incremented by its speed at a later point as well. Finally, since the point used for the collision calculation is only written to the Bob-omb's position if a collision occurs, the double speed increment doesn't happen in the open field." | Tyler, in discord: "@Kaztalek and others who were thinking there were a couple speed vectors being added were basically spot on.

Basically, Bob-ombs always check for wall collision before moving. If they do collide with a wall hitbox, then the Bob-omb's position is incremented and pushed away by the wall. | |||
This is before the Bob-omb's actual movement step occurs, so then it moves a 2nd time before the frame ends. Thus, when Bob-ombs touch a wall, their speed is effectively doubled. | |||
