How do I get his line of code to work now, with the newer lite-c version:

view = camera;

Whenever I define an entity with this, I cannot see the entity in the 3d world. Any help?

Do you mean to make an entity visible only in that view? AFAIK entities do not have a "view" parameter, but you can set up which entities are visible in which views using material events.

Yes I want to make a gun for a FPS or a pickup for a player in my game. How can I accomplish this?

Ah, I get it. Are you using a view entity?
eg:

Can I shoot bullets from this entity, by using this code?:

action playerweapon()
{
minig = my;
VECTOR wpnht;
VECTOR wpnoffset;
set(my,PASSABLE);
while(1)
{
vec_set(wpnoffset.x, vector(50,-18,-20));
vec_rotate(wpnoffset.x, vector(camera.pan, camera.tilt,0));
vec_add(wpnoffset.x, camera.x);
vec_set(my.x, wpnoffset.x);
my.pan = camera.pan;
my.tilt = camera.tilt;
wait(1);
}
}

function rmvblts()
{
ent_create("bullethole.pcx", vector(my.x,my.y,my.z), NULL);
set(my,PASSABLE);
set(my,INVISIBLE);
ent_remove(my);
}

function mvbllt()
{
VECTOR bspeed, trceblt;
set(my,ENABLE_IMPACT);
my.event = rmvblts;
my.pan = camera.pan;
my.tilt = camera.tilt;
bspeed.x = 200 * time_step;
bspeed.y = 0;
bspeed.z = 0;
vec_set(trceblt, vector(75,0,0));
vec_rotate(trceblt,camera.pan);
vec_add(trceblt, camera.x);
while(my!=NULL)
{
c_move(my,bspeed,nullvector,IGNORE_PASSABLE);
if(c_trace(my.x, trceblt, IGNORE_PASSABLE| USE_POLYGON| SCAN_TEXTURE)>0)
{
rmvblts();
}
wait(1);
}

}

function firegun()
{
proc_kill(4);
vec_for_vertex(temp.x, minig, 53);
ent_create("bullet.mdl", temp.x, mvbllt);
wait(0.14);
}

Also do you know why whenever I hit a rigid body (a barrel with a box bounds) the bullet will not destroy itself?

Okay, with that kind of code you don't want to use an "ENTITY* =" definition like I showed (that creates a view entity that only functions in view space). The way you're doing it has advantages of easier lighting (dynamic lights interacting with view entities can be problematic), and the disadvantage of slightly more difficult to code.

Some things I noticed:
-- What's with the "wait(0.14);" in the firegun() function? Use negative numbers for seconds (or fractions of seconds), eg "wait(-0.14);".
-- You also want the bullet to have the event-flag "ENABLE_ENTITY" -- ENABLE_IMPACT only triggers when another entity moves into the bullet. ENABLE_ENTITY will trigger when the bullet hits another entity. If you have level blocks, also use ENABLE_BLOCK. You don't really need ENABLE_IMPACT at all.
-- I have no idea why you're tracing to 75 quants in front of the camera in the bullet action.

I hope those points are useful!

I could never get the ent_decal command to work correctly. Whenever I tried to make a decal, I always got an error.
Here is the code:

function spawn_sprite()
{

proc_kill(4); // stops the function from running more than 1 time
// spawn a sprite at mouse click position, 200 quants behind the screen

while (key_space) {wait (1);}

vec_set(temp.x,camera.x);
vec_set(temp2,vector(20000,0,0));
vec_rotate(temp2,camera.pan);
vec_add(temp2,camera.x);
trace(temp,temp2);
ent_create("bullethole.pcx",target,NULL);
//ent_decal(you,"bullethole.tga",you.x, you.y);
}



function makedecals()
{
// calculate the target vector
VECTOR trace_target;
vec_set(trace_target,vector(5000,0,0)); // the weapon has a firing range of 5000 quants
vec_rotate(trace_target, camera.pan);
vec_add(trace_target, camera.x);

// display a red spot at the target position
if (c_trace(camera.x,trace_target, IGNORE_PASSABLE | USE_POLYGON| SCAN_TEXTURE) > 0) // hit something?
{
draw_point3d(hit.x,vector(50,50,255),100,3);
}//ent_create("hairs.bmp", hit.x, NULL);


// fire and then place a decal at the hit position
if (key_space) // fire
{
if (HIT_TARGET) // target hit?
{
//spawn_sprite();
//p = ent_decal(you,"bullethole.tga",7+random(3),random(360)); // place a random sized decal at the hit entity
//p.lifespan = 1600; // remove decal after 100 seconds
}
//PARTICLE* p = ent_decal(you,bmMark,you, 5); // place a random sized decal at the hit entity
// p->lifespan = 80;
//hit.x);
//ent_create("bullethole.tga",vector(hit.x,hit.y,hit.z),NULL);
//ent_decal(you,bmMark,you, 5);
}
wait(1);
}

Any advice?

Here is another link to the code as well:

I haven't used ent_decal before. Sorry; hopefully someone else can help there.

Could you please use code tags to make your code easier to read? Just put your code between tags like this: [code ] blah..blah blah... [/ code] (without the spaces in the tags). It allows the forum to preserve whitespace (indents and what-not) and makes it easier to read.

I think it wont work if you use you as 3rd and 4th parameter since you can be NULL at anytime...

Sorry if I dont use indentation.
The rmvblts function only remove itself, you could add ent_remove(you) somewhere in the function but it will be simpler if you add ent_remove(me) in the end of mvblts function like this:

Do you know how to create a decal that actually works?
Whenever I try to make one, I always receive an error.
