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 : The X/Y position of the layer relative to the Pawn, the pattern number offset from the pattern number defined in the animation, the sprite color and a special flag for display.

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 },
};
