post render rotate

[havenphillip]

How can you rotate one thing in PostRender() without rotating everything? Is there a way without using shaders?

Oh wait, I think I'm getting it.

Nope. I got the square moving all over the screen but it won't turn. Here's my script:

Script.pos = Vec2(242,234) -- Vec2 "Position"
Script.offset = Vec2(4,3) -- Vec2 "Offset"
Script.csize = Vec2(200,200) -- Vec2  "Size"
Script.square = Texture:Load("Materials/Developer/bluegrid.tex")

function Script:PostRender(context)
    Time:Update()
        
    local a = Time:GetCurrent()*0.1
   
    local x = self.pos.x
    local y = self.pos.y
    local w = self.csize.x
    local h = self.csize.y
        
    local scale = 1
    
    --context:SetRotation(a)
    context:SetScale(scale,scale)   
        
    context:SetBlendMode(Blend.Alpha)
    context:SetColor(1,1,1)
    context:DrawText(text,x,y)
    context:DrawImage(self.square, x-(Math:Cos(a)*(w) - Math:Sin(a)*(h)), y+(-Math:Sin(a)*(w) - Math:Cos(a)*(h)) , self.csize.x, self.csize.y)
    context:SetBlendMode(Blend.Solid)
end

I see. You have to reset context:SetRotation(0) at the bottom.
