Field Documentation

SDL_Rect Obstacle_t::loc

The location of the obstacle in game coordinates.

These coordinates do not include a subpixel position.

Definition at line 46 of file obstacle.h.

Referenced by HandleObstacle(), IsCollidingObstacle(), MakeBuffers(), and ObstacleInit().

RenderItem Obstacle_t::ri

The data used by the rendering system to draw the obstacle.

The coordinates used in ri are screen coordinates and not game coordinates; they should not be used in game play code and need to be kept in sync with the game coorinates. The only times the coordinates should need to be synchronized are when the obstacles are first created, and if the obstacles move on the battle field (but they shouldn't).
