Function Documentation

draw_color()

void draw_color ( lua_State * L, union color_u * colorptr )

extern

draw_queue_push()

void draw_queue_push ( lua_State * L, uint8_t func )

extern

erase_screen()

void erase_screen ( )

extern

native_draw_clear()

static int native_draw_clear ( lua_State * L )

static

std.draw.clear

Parameters

[in]

color

int

Warning

Changing the color that is clearing the screen is expensive, it will take 2 to 3 frames, so avoid changing the color constantly.

Here is the call graph for this function:

native_draw_color()

static int native_draw_color ( lua_State * L )

static

std.draw.color

Parameters

[in]

color

int

Here is the call graph for this function:

native_draw_flush()

static int native_draw_flush ( lua_State * L )

static

native_draw_font()

static int native_draw_font ( lua_State * L )

static

std.draw.font

Parameters

[in]	font	string
[in]	size	double

Warning

long texts are currently expensive and impact vertical synchronization, if you happen to experience flickering, change FPS_MODE to 3 or focus on smaller texts and at the bottom of the screen.

native_draw_install()

void native_draw_install

(
