light sensitivity

[Silve]

Hi

We are trying to make a monster that avoids light, more exactly light from the players flashlight (which is a SpotLightMovable).

All that‘s needed is to check if the monster is in an illuminated area or not. Preferably this is done by actually checking how illuminated it is, alternative is to fake this by checking if the monster is within the arc of light that the flashlight casts.

Any help with how to do this is appreciated
Thanks.

You'll have to fake it. Try setting up some kind of collision primitive in where your light source is, then using traces to see if there is any obstruction between the monster and light source.

Cool idea mate, reminds me of scenes from Condemned, those wierd little anorexic mutated crack addicts (or whatever they were). One of the scariest games ever made, without a doubt!

I have got a trace working that originates from the playerPawn, but I want it to originate from the flashlight. The problem is that the flashlights position and rotation never changes, I guess it have to do with it being attached to the player? Is there any solution for this?

[ambershee]

The flashlight position / rotation has to change, because it is attached to the player.

Are you confusing world and local coordinate systems somewhere?

[Silve]

Yes of course but when I try to get its location and rotation it is always the same even when I move around.

Sounds like you're trying to get the position of the wrong object, or something similar. You'll have to post code if you want someone to help you.

Right, well this is my code so far. It is located within my playerPawn, mostly because I want those 3D lines to be drawn and I don't know any better way to get hold of the HUD.

var AU_Flashlight flashlight;

event Tick(float DeltaTime)
{
	flashlight = AU_Flashlight(InvManager.FindInventoryType(class'AU_Flashlight'));
	
	Pos = flashlight.Location + (vector(flashlight.Rotation)*300);
	
	hitActor = Trace(HitLocation, HitNormal, Pos, flashlight.Location, FALSE,, hitInfo);
	//hitActor = Trace(HitLocation, HitNormal, Pos, Location, FALSE,, hitInfo);

	Paint.G=0;
	Paint.B=0;
	Paint.R=100;
	AU_PlayerController(Controller).DrawTraceLine(HitLocation,Pos, Paint);
	Paint.G=100;
	Paint.B=0;
	Paint.R=0;
	AU_PlayerController(Controller).DrawTraceLine(flashlight.Location,HitLocation, Paint);
}

I have tested and it does find the right flashlight.
