= t3set =
== Syntax == void t3set(int x, int y, int z, int v) == Arguments == :x ::An integer pixel x-coordinate in the third tile buffer. :y ::An integer pixel y-coordinate in the third tile buffer. :z ::An integer color channel number in the range 0 to 3. :v ::An integer pixel color value to be set for color channel 'z', in the range 0 to 255. == Description == This function sets the value of one channel for a pixel in the third tile buffer; the pixel is at coordinates [x,y], and the channel to be set is given by 'z' (0 = red, 1 = green, 2 = blue, and 3 = alpha). == Example == <code> %ffp ForEveryTile: {for (y=y_start; y<y_end; ++y) { for (x=x_start; x<x_end; ++x) { for (z=0; z<Z; ++z) { // set all pixels white t3set(x, y, z, 255); } } } return true; }</code> == See Also == |
