Rotating Fan with light effect in COD4 - AmishThunder
www.kramerartanddesign.com

This tutorial involves some scripting and lighting familiarity, lets get dirty.

Create your area you want your fan and light.

First make a fan.
Right click on the grid -> script -> script_model
Select the model "icbm_turbofan64" or any other size you want.
Now give it the "Key/Value" of "targetname / fan1"

Now make your spot light.
Create your light entity, null, and connect them.
Refer to Lighting 101 if unsure how.
Select "Primary_Spot" for your light and customize the rest so that the light clearly touches the surface you want your shadow on..

You are now done in your map!

--------------------------------------------------------------

Lets begin the scripting part, its not has hard as you may suspect.

Open your .gsc
If you don't have one yet then open "mp_test.gsc" and adjust accordingly with your map name.

Create your thread
Add this to the first main() bracket.


Now under the last } for the main() bracket add this code.


You may add as many fans as you like but copy a new segment and up the number by 1.

Can we shelve the tuts for cod4 along with the constant inquiries of the whereabouts of the mod tools until, well, people actually have the mod tools.

Yeah. It's jealousy. I'm not bashful.

whahahahaha yeh its sorta like a custard pie aint it rub it in your face lol

You can clean that code up a bit though, maybe get rid of some of the comments.

fanSpin() 
{
fan1 = getEnt( "fan1" , "targetname" );
while (1)
{
fan1 rotateyaw( 360, 5, 0, 0 );
wait 4.9;
}
}

I think, this code is more usable for more fans

fanspin()
{
	fan = getentarray("fan", "targetname");
	for(i = 0; i < fan.size; i++)
		fan[i] thread fanrotate(randomint(4) + 2);
}

fanrotate(speed)
{
	while(1)
	{
		self rotateyaw(360, speed, 0 ,0);
		wait(speed - 0.1);
	}
}

That way all fans must have the same targetname (fan).
If you add more fans, you don't need to touch the code.
All fans are caught by the code and rotate with random speeds.

The code was meant to be user friendly to the new scripters out there and the comments were for explanation. However with any script, there are hundreds of ways to do the same thing.

How are you guys making maps for cod4 if the tools havnt been released yet?

'Some' people have the beta release of the tools.

I'm glad this tuts up- i wanted to do this once the tools were released

would u do this the same way in cod2 radiant?

No, COD2 does not have any real dynamic lights.
