Adding GodRays

[metaldc4life]

Hi,

I was needing help with this script for godrays please..

 

camera->SetKeyValue("godray_pos", std::string(Vec3(-x, -y, -z)));

 

I get the error below:

 

 

"C:/Users/Gaming Rig/Documents/Leadwerks/Projects/MyGame/scripts/godrays.lua" : 1 : '=' expected near '-'

That is C++ code, you are using Lua.

 

Changing -> to : fixes your initial error, but you'll get another error once it gets to std::string

 

I haven't seen the god ray script but I think this is what you need:

camera:SetKeyValue("godray_pos", Vec3(-x, -y, -z));

oh...lol

i'm new to all this but LOVE it.

 

anyways, thank you i'll try it out! =)

well, I tried it and I got this:

 

"C:/Users/Gaming Rig/Documents/Leadwerks/Projects/MyGame/scripts/godrays.lua" : 1 : attempt to index global 'camera' (a nil value)

Self.camera or where ever you store the camera reference

Hi

 

Thanks for the reply but what do you mean by where I store it I don't understand?

[metaldc4life]

I think I'm starting to understand a little now and if my theory is correct, the reference would be in the player script and I would use this line somehow:

self.camera = self.Camera

 

but how would I implement it into this script properly?

 

camera:SetKeyValue("godray_pos", Vec3(-x, -y, -z));

You can attach this to your directional light as a script to get the correct calculations :

 

function Script:Start()

 

self.world=World:GetCurrent()

if self.camera==nil then

for i=0,self.world:CountEntities()-1 do

if self.world:GetEntity(i):GetClass()==Object.CameraClass then

self.camera=self.world:GetEntity(i)

tolua.cast(self.camera,"Camera")

System:Print(self.world:GetEntity(i):GetClassName())

break

end

end

end

 

if self.camera then

local light=self.entity

self.dir = Vec3(light.mat.k.x,light.mat.k.y,light.mat.k.z):Normalize()

--sun raw position is then:

self.sunrawpos=Vec3(-self.dir.x,-self.dir.y,-self.dir.z)

self.camera:SetKeyValue("godray_pos",self.sunrawpos:ToString())

end

end

got it working!

thanks!

do you happen to know how to adjust the x, y axis on the mouse because I have this water script that I downloaded from klepto that I attached to the player but it won't let me look up or down.. it prevents me from looking up or down...

Thanks again!
