| union { | |
| struct { | |
| Bool dirty: 1 | |
| Flag that indicates the item has changed since last drawn and the change is visible. | |
| Bool enableDraw: 1 | |
| Flag that indicates the item should be drawn; this flag is not cleared in Render(). | |
| Bool placed: 1 | |
| Flag that indicates the item was placed with PlaceRenderItem() since the last frame was rendered. | |
| Bool transparent: 1 | |
| Flag that indicates the item has transparency. | |
| Bool visible: 1 | |
| Flag that indicates the item is within the viewable area. | |
| } | |
| Uint32 flags | |
| A set of bit flags used to hold render state information. | |
| }; | |
| void * | data |
| A pointer to application defined data. | |
| SDL_Rect | loc |
| The logical (world) location of the item relative to the layer. | |
| RenderItem * | next |
| A pointer to the next item in the list of all visible items. | |
| Layer * | parent |
| The owning layer of this item. | |
| SDL_Rect | physDest |

| RenderItem * | prev |
| A pointer to the previous item in the list of all visible items. | |
| SDL_Rect | prevStates [2] |
| Stores physical coordinates of previously visible locations. | |
| Sint16 | rectIndex [2] |

| Uint32 RenderItem_t::flags |
| SDL_Rect RenderItem_t::loc |
The logical (world) location of the item relative to the layer.
The rendering system will not set or change the value of loc.

A pointer to the next item in the list of all visible items.
Definition at line 274 of file render.h.
Referenced by AddRenderItem(), ObstacleInit(), and RemoveRenderItem().
The owning layer of this item.

Referenced by AddRenderItem(), ObstacleInit(), PlacePlayerLabel(), and RemoveRenderItem().
| SDL_Rect RenderItem_t::physDest |
The destination coordinates on the physical display.
This value is clipped to the display and to the union of region that has changed and regions that require an update because of other items changing. At the time renderer is called, src will contain the item relative coordinates of what must be drawn onto the rectangle in physDest.

| Sint16 RenderItem_t::physLocX |
The physical display location where the item is placed.
The width and height are no different than the size of the item as stored in loc.
Definition at line 354 of file render.h.
Referenced by DrawTank(), and main().
| Sint16 RenderItem_t::physLocY |
Flag that indicates the item was placed with PlaceRenderItem() since the last frame was rendered.
This helps avoid duplicating calculations during rendering.
For internal use only.

Referenced by RotateTank().
A pointer to the previous item in the list of all visible items.

Referenced by AddRenderItem(), ObstacleInit(), and RemoveRenderItem().
| SDL_Rect RenderItem_t::prevStates[2] |
Stores physical coordinates of previously visible locations.
Index zero stores the location for the last frame, index one stores the frame before the last, ect . . . The width field must be zero if the item was not visible in the corresponding frame.

Referenced by ClearRenderItem().
| Sint16 RenderItem_t::rectIndex[2] |
The function which renders the item.

| SDL_Rect RenderItem_t::src |
The region of the item that must be rendered in the next frame.
The rendering system will change the value of src to clip it to the viewable area and to extend it if needed to draw over an area made dirty by another update.
Definition at line 294 of file render.h.
Referenced by AddRenderItem(), and GenericSurfaceRenderer().
Flag that indicates the item is within the viewable area.
