heyo. I'm trying to have a light follow you around but my script isn't working. I've placed a light in radiant with the targetname "light_a" and I've called this function in the main one. Code Snippet Plaintext Copy function light(player) { light = GetEnt("targetname","light_a"); light EnableLinkTo(player); light LinkTo(player); }

How to make a following light? in Scripting

First of all, you're using improper syntax in two of your functions. When you do:

Code Snippet

Plaintext

light = GetEnt("targetname", "light_a");
//This is asswards ^
//Proper way

light = GetEnt("light_a", "targetname");

Then you have this:

Code Snippet

Plaintext

light EnableLinkTo(player);
//This is wrong ^
//EnableLinkTo doesn't take any arguements
//Right way
light EnableLinkTo();
//then
light LinkTo(entity)

I haven't tried using a "radiant light" in script, however you can easily use an "FX light" to accomplish what you need. First of all, open radiant, go to the fx browser, and find a good fx light that you want to use, or create/edit your own. Then in script, when you are ready to spawn the "following light", you need to get the player first. For testing purposes, just drop down a trigger_use, give it a targetname like "fxlight". Then in script, do:

Code Snippet

Plaintext

#precache("fx", "name_of_fx_file");
#namespace FXlightFollower;

function init(){
	level._effect["fx_light"] = "name_of_fx_file";
}

function fx_light(){
	FXtrig = GetEnt("fxlight", "targetname");
        FXtrig SetCursorHint("HINT_NOICON");
        FXtrig SetHintString("Press &&1 to summon light fx");
	FXtrig waittill("trigger", player);

	fx_follower = Spawn("script_model", player.origin + (0, 0, 80));
	fx_follower SetModel("tag_origin");
	PlayFXOnTag(level._effect["fx_light"], fx_follower, "tag_origin");

	player.light_follower = fx_follower;
	player thread light_follow();
}

function light_follow(){
	while(1){
		halo = self.origin + (0, 0, 80);	//80 units above the player - adjust height as necessary
		self.fx_follower MoveTo(halo, .05);
		wait(.05);
	}
}

//When you're ready to stop the fx, do:
		self.fx_follower Delete();

Don't forget to add the fx in your zone file. Go to launcher, right-click your map, and click 'edit zone file', then add:

Code Snippet

Plaintext

fx,fx_file_name

Then obviously you need to thread the init() function, and the fx_light() function in your mapname.gsc, so put the fx light scripts into it's own gsc file, so the #namespace command makes the init() function local. Ex.

Code Snippet

Plaintext

//In your mapname.gsc
your_fx_script_gsc::init();          //<--Pre-load
zm_usermap::main();               //<-- Main - already in your mapname.gsc
your_fx_script_gsc::fx_light();  //<--Post-load

Hope this helps. I've done similar things with fx so I know this method works. However there are usually always multiple ways to do any one task in coding, generally speaking. As for the "link to" method, what you're looking for if you want to go that route is to use an offset on the z-axis, so the light spawns above the player and shines down on them. So, if you use the link to method, then do it like this:

Code Snippet

Plaintext

fx_follower = Spawn("script_model", player.origin + (0, 0, 80));
fx_follower SetModel("tag_origin");
fx_follower EnableLinkTo();
fx_follower LinkTo(player, "tag_origin", (0, 0, 80));
PlayFXOnTag(level._effect["your_fx"], fx_follower, "tag_origin");
//Then do:
fx_follower Delete();
//When you're ready to stop the fx
