Create radial gradient

#1

Hi my name is Erick and first of all, i’m new at Corona, and have been reading the forum and the community just seems great in support and collaboration, so in advanced tnx to everyone 'cause even without touching the SDK i have learned a lot just with that.

My first question here is about drawing a radial gradient, i have found a linear gradient script and i wanted to know if there is something similar for a radial…

Tnx again for your time and sharing.

Here is some pseudo code …

[code]
for i = 0, height, 2 do

local percent = i/height;
local amt = (1.0 - percent );
myRed = amt * rr + percent * r
myGreen = amt * gg + percent * g
myBlue = amt * bb + percent * b
local newRect = display.newCircle(display.contentWidth/2,display.contentHeight/2,radius);
newRect:setFillColor(myRed,myGreen,myBlue,255);
radius = radius - 2;
end

I’m wondering about the linear gradient script you said you already had. I haven’t been able to track down an example of that. Can you post that? [import]uid: 3671 topic_id: 5825 reply_id: 29243[/import]
