fullbright surface?

[Yue]

How can I make the surface of the flashlight where the light is projected shine?

[SpiderPig]

A bloom post effect maybe?  Or if your talking about the lens of the light you'll need an emission material.

[Yue]

How do I create a broadcast material? How do I create an emission material? so that the lens looks shiny?

[SpiderPig]

There's bloom.lua in the posteffects folder under the shaders folder in your project.  I think you add that to your camera as a post effect.

For an emission shader I think you just need to change the shader from diffuse.shader to emission.shader in the material editor.  I haven't used Leadwerks in a while though.

light:SetColor(2,2,2)

You want the scene to reflect on the helmet visor?

[Yue]

Yes, this works with an emissive material, so the idea is that it only works when the flashlight is on, I guess I have to change the material from the script.

[havenphillip]

Oh I see what you're doing. You could use a single material to do it. The thing that makes emission is really simple it's just the first three vectors of the specular output.

You could set up an if statement in the shader something like this:

 

uniform float light_on;


....


if (light_on == 1.0) {

fragData2 = vec4(1,1,0,1);

}

else {

fragData2 = vec4(0,0,0,specular);

}

 

Then in your script somewhere you set the float and set it to the flashlight function. Something like:

 

Script.flashlightOn == 0.0


...

self.shader:SetFloat("light_on",self.flashlightOn)


function Script:UpdatePhysics()

...

    --Toggle the flash light on and off
    if window:KeyHit(Key.F) then
        if self.sound.flashlight~=nil then self.sound.flashlight:Play() end
        if self.flashlightOn == 0.0 then
            self.flashlightOn == 1.0
        else
            self.flashlightOn == 0.0
        end
    end
