Lights / Lighting Issues
by Rob Evans · in Torque X 2D · 05/15/2007 (5:34 am) · 7 replies
I'm trying to get a single light to work in my scene. The code I'm using is:
T2DSceneObject testLight = new T2DSceneObject();
LightRegisterComponent lightRegister = new LightRegisterComponent();
DirectionalLightInfo lightInfo = new DirectionalLightInfo();
lightInfo.AmbientColor = new Vector3(255.0f, 255.0f, 255.0f);
lightInfo.DiffuseColor = new Vector3(255.0f, 255.0f, 255.0f);
lightInfo.Direction = new Vector3(0.0f, 0.0f, 0.0f);
lightRegister.LightList.Add(lightInfo);
testLight.Components.AddComponent(lightRegister);
testLight.Visible = true;
testLight.Position = new Vector2(0.0f, 0.0f);
I've set my background material to translucency off and enableLighting true in my txtscene file as so:
BackgroundMaterial
DefaultEffect
data\images\palmtrees.png
true
false
I expected the light to light up an area of the background image but all I see is darkness...
I've checked other threads on this subject but can't see how I fix this problem.
Any suggestions?

Opps, I posted the wrong material... the lighting on my object is set to true... still doesn't work...

My material looks like this:

The light direction is {0.0f, 0.0f, 0.0f}, make sure to give the light a valid direction (as a unit/normalized vector).

I'll describe what I'm doing. I've got a big background image on layer 10 and a number of other sprites at layer 1. I want a light to mount to my sprites to light up the background as the sprites move around.
Imagine a dark picture and glowing bugs flying around and the pic being illuminated as they fly.
How can I do that?

What's a normalised vector? LOL.I'll describe what I'm doing. I've got a big background image on layer 10 and a number of other sprites at layer 1. I want a light to mount to my sprites to light up the background as the sprites move around.

If you want the light to point straight down from your sprites, try making one of the vector's components 1 or -1. Experiment with Z. Not sure, but give it a shot.

A normalized vector is a vector whose length is one unit.If you want the light to point straight down from your sprites, try making one of the vector's components 1 or -1. Experiment with Z. Not sure, but give it a shot.
