Post subject:  bug in Poly and fillpoly functions
I have found bug in function poly and the same bug in fillpoly

fillpoly(red, green, blue [,px, py][,px, py][,px, py]....)

red, green - changes color but somehow olso became first coordinates px and py
then forth coordinates and left does't work it all.

for ex. please try to use this function instead of fillrect and see what you get :)

Yes, i found the bug, interested functions are poly and fillpoly (not fillrect).
This will be fixed in next release.

O, Thanks a lot in last version 0.2.0.135
Poly and fillpoly now works properly.

But i have something like suggestion or may be question
is it possible to use fillpoly or poly function with arrays.
I mean
can i use this functions like this:
local part={}
local maxparts=200
for c=0, maxparts do
part[c]={}
part[c]["x"]=math.random(0, screenwidth())
part[c]["y"]=math.random(-screenheight(), -20)
end

Poly (r ,g, b, part[c]["x"], XStart,part[c]["y"], YStart, Count)

instead of sample:

poly(r, g, b,
math.random(0, screenwidth()), math.random(0, screenheight()),
math.random(0, screenwidth()), math.random(0, screenheight()),
math.random(0, screenwidth()), math.random(0, screenheight()),
math.random(0, screenwidth()), math.random(0, screenheight()),
math.random(0, screenwidth()), math.random(0, screenheight()),
math.random(0, screenwidth()), math.random(0, screenheight())
)



Thanks

You can obtain that (or similar) using the unpack LUA function:

Code:
        
local myarr={}
myarr[1]=10
myarr[2]=10
myarr[3]=40
myarr[4]=10
myarr[5]=40
myarr[6]=40
myarr[7]=10
myarr[8]=40
fillpoly(255, 0, 0, unpack(myarr))


Look here and here for more info
