Weird Syntax error.

Graphics Shaders & Materials
1

So I am getting a syntax error in my shader’s compiled code:

SubProgram "xbox360 " {
Keywords { }
Bind "vertex" Vertex
Vector 0 [$_color]   //<--RIGHT HERE

My properties:

Properties 
	{
		twisting("twisting",Float) = 0.5
		_color("color",Color) = (1,1,1,1)
	}

I don’t know whats wrong, pretty new to CG.

I don’t really use much shader lab, what is the Vector command for? Can’t find any documentation for it.

The error seems to come somewhere from your actual Cg/HLSL code. How do you declare “color” variable there? The compiler seems to think it’s named “$_color” which is not a very valid name.

Yeah I noticed that. But I really don’t know enough about CG yet to figure out why its thinking its $_color. And only for Xbox 360.

The Vector command is just a way to hold points. Essentially it is an array (very loosely, but best “programming” way I can think to describe it).
