hit.texname
Gets the name of the model, sprite or block texture that was hit by a c_trace instruction.
STRING* name_str = " ";
function fire_bullets() // use a weapon that fires bullets using c_trace with SCAN_TEXTURE
{
while (mouse_left)
{
c_trace(camera.x, trace_coords.x, IGNORE_ME | IGNORE_PASSABLE | SCAN_TEXTURE | ACTIVATE_SHOOT);
str_cpy(name_str, hit.texname);
if (!you) // hit a wall?
{
ent_create (hithole_tga, target.x, display_hithole); // then create a bullet hit hole
}
snd_play (bullet_wav, 100, 0); // play the bullet sound at a volume of 100
ent_create("muzzle+20.tga", nullvector, attach_muzzle);
wait (-0.16); // fire 6 bullets per second (6 * 0.16 ~= 1 second)
}
}
TEXT* texture_txt =
{
layer = 10;
pos_x = 20;
pos_y = 20;
string(name_str);
flags = VISIBLE;
}
exec_wait (name, options)
Starts the program with the given name and then suspends the execution of the current function or action until the started program is terminated.
function notepad_startup() // copy notepad.exe inside this project's folder
{
wait (-1); // wait until the entire level is loaded
exec_wait ("notepad.exe", NULL); // launch notepad.exe
beep(); beep(); // these beeps will be heard only after you close notepad
wait (-3); // the execution of the code is resumed here
sys_exit(NULL); // but we'll simply shut down the engine
}
Improved debugging
Crashes in lite-C now always give the name of the crashed function.
