Random color select in a faster way

[Nick]

I was looking for a fast way to switch between colors for my tetris project, so i tried to find a faster way of choosing a color and setting it with setColorRGB(). I don't know if it's the fastest way, but it goes nice and the colde is tidy
It's only to get the most basic colors: Red, Green, Blue, turquoise, pink, orange and yellow.

This is what you would have normally (or better, i had):

Code: Select All | Copy To Clipboard

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

color = math.random(1,7) if color == 1 then gc:setColorRGB(255,0,0) elseif color == 2 then gc:setColorRGB(0,255,0) elseif color == 3 then gc:setColorRGB(0,0,255) elseif color == 4 then gc:setColorRGB(255,0,255) elseif color == 5 then gc:setColorRGB(0,255,255) elseif color == 6 then gc:setColorRGB(255,255,0) elseif color == 7 then gc:setColorRGB(255,150,0) end

and this is what you get now:

Code: Select All | Copy To Clipboard

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

color=math.random(1,7) colortable={0,0,0} if color<=3 then          colortable[color]=255 elseif color==4 or color==5 then          colortable[3]=255          colortable[color-3]=255 elseif color==6 then          colortable[1]=255          colortable[2]=255 else        colortable[1]=255          colortable[2]=150 end gc:setColorRGB(colortable[1],colortable[2],colortable[3])

both results are the same (luckily xp )



does anyone know if this is more relevant than the upper one?

You could use this:

Code: Select All | Copy To Clipboard

1 2 3

colortable = {{255,0,0}, {0,255,0}, {0,0,255}, {255,0,255}, {0,255,255}, {255,255,0}, {255,150,0}} setColorRGB(unpack(colortable[math.random(#colortable)]))

This way you can easily add colors, and it will continue to work

wow, that looks really easy thanks! now my code will finally get a little more tidy

but i do not understand the unpack method, what does it do? (always wanting to learn something new xp)

[Chockosta]

When you type unpack({1,2,3}), the function returns 1,2,3.
It basically unpacks a table.

[Nick]

oh, thanks a lot, that might be useful for some other functions too

Good method for doing this!  The unpack command looks quite helpful.

Apcalc, mind sharing your technique for your Axe tunnel? Becuase your game seemed to flash between colors even faster than in  the screenshot above. Both are nice nonetheless, though.
