The game_pawn module handle character animation, rendering, collision and physics.
This module offer several structures the user can use to configure a pawn (a player, an enemy or any moving object) for rendering (multi-layers and flip/flap) and movement.
Dependencies
Settings
GAMEPAWN_USE_PHYSICS: Include collision and physics handling functions.
Usage
Define pawn's sprites
The visual of a pawn is displayed by one or more sprite layers. The 'Game_Sprite' structure allows to define the parameters of each layer.
Examples
Simple color sprite (1 layer): const Game_Sprite g_SpriteLayers[] =
{
{ 0, 0, 0, COLOR_WHITE, 0 }, // Sprite position offset: 0,0. Pattern offset: 0. Color: White. No special flag
};
Two color sprite (2 layer): const Game_Sprite g_SpriteLayers[] =
{
{ 0, 0, 0, COLOR_WHITE, 0 }, // Sprite position offset: 0,0. Pattern offset: 0. Color: White. No special flag
{ 0, -8, 4, COLOR_GRAY, 0 }, // Sprite position offset: 0,-8. Pattern offset: 4. Color: Gray. No special flag
};
3 layers sprite with auto-switch (to generate more color by flickering) const Game_Sprite g_SpriteLayers[] =
{
{ 0, 0, 0, COLOR_BLACK, PAWN_SPRITE_EVEN }, // Sprite used only on 'even' frame number
{ 0, 0, 12, COLOR_BLACK, PAWN_SPRITE_ODD }, // Sprite used only on 'odd' frame number
{ 0, 0, 4, COLOR_WHITE, 0 },
{ 0, 0, 8, COLOR_LIGHT_RED, 0 },
};
