hello

sorry i am still newbie

i donot know how to call function

here is part of my game.wdl
Code:

---

 The main() function is started at game start
function main()
{
init_controls();
// set some common flags and variables
//	warn_level = 2;	// announce bad texture sizes and bad wdl code
	tex_share = on;	// map entities share their textures

// center the splash screen for non-800x600 resolutions, and display it
	splashscreen.pos_x = (screen_size.x - bmap_width(splashmap))/2;
	splashscreen.pos_y = (screen_size.y - bmap_height(splashmap))/2;
	splashscreen.visible = on;
// wait 3 frames (for triple buffering) until it is flipped to the foreground
	wait(3);

// now load the level
	level_load(level_str);
// freeze the game
	freeze_mode = 1;

// wait the required second, then switch the splashscreen off.
	sleep(1);
  	splashscreen.visible = off;
	bmap_purge(splashmap);	// remove splashscreen from video memory

// load some global variables, like sound volume
	load_status();

// display the initial message
	msg_show(mission_str,10);

// initialize lens flares when edition supports flares
ifdef CAPS_FLARE;
	lensflare_start();
endif;

// use the new 3rd person camera
	move_view_cap = 1;

// un-freeze the game
	freeze_mode = 0;

//	client_move();	// for a possible multiplayer game
// call further functions here...
targetstart();
startcompass();
ismeniu();
}
