Functions | |
void | AddRenderItem (RenderItem *item, int layer) |
Adds a new RenderItem to the world list of a Layer. | |
static void | AddToUpdateLists (RenderItem *item, SDL_Rect *rect) |
Adds a rectangle to the update lists. | |
void | ClearRenderItem (RenderItem *item) |
Makes an item no longer visible until the next PlaceRenderItem() call on the item. | |
static Bool | FindNextCollision (RenderItem *item) |
Finds the next rectangle in the update list that the given item collides with and sets the physDest field to the overlapping region. | |
void | ForceDirtyFrame () |
Set the dirty flag to force the renderer to perform a partial redraw for the next frame. | |
void | ForceRenderAll () |
Force everything to be redrwan for the next frame. | |
void | GenericSurfaceRenderer (SDL_Surface *dest, RenderItem *item) |
Renders a surface pointed to by item->data. | |
void | PlaceRenderItem (RenderItem *item) |
Places a render item on the physical display based on information set within the item. | |
void | RemoveRenderItem (RenderItem *item) |
Removes a RenderItem from a Layer. | |
void | Render () |
Renders a frame. | |
void | RenderClearStates (Uint8 numStates) |
Clears all display state information and optionally changes the number of states to use. | |
Bool | RenderInit (Uint16 numRects, Uint8 numStates) |
Initalizes the rendering system. | |
void | RenderUninit () |
Uninitializes the rendering system. | |
Bool | RenderWillRenderAll () |
Tells if the next call to Render() will render an entire frame rather than just a changed portion. | |
Bool | ResizeWindow (Uint16 w, Uint16 h) |
A utility function for resizing the program's window. | |
void | SetLayerOffset (Layer *layer, Sint16 x, Sint16 y) |
Changes the layer's offset from the physical display. | |
void | SolidFillRenderer (SDL_Surface *dest, RenderItem *item) |
Renders a solid rectangle who's color is stored at item->data. | |
Variables | |
DisplayInfo_t | dInfo |
Global information about the display. | |
Layer | layers [6] |
The global set of Layers. | |
static struct UpdateList_t | updateList |
Contains a list of rectangles that must be updated. | |
Uint32 | videoFlags = 0 |
The SDL video flags used in all calls to SDL_SetVideoMode(). |
