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();
