View list of data type meanings


Sets a single pixel in the miniwindow.

Note that changes to miniwindows will not become visible until the output window is redrawn. This happens when new (visible) lines arrive from the MUD, or if you call WindowShow, or Redraw.


WindowName - the name of an existing miniwindow.

x, y - the location of the pixel (x is horizontal, y is vertical)

Colour - the colour to set the pixel to. Note that the pixel which appears in the window may not necessarily be the exact one you chose, depending on the colour depth of your monitor. For example, for 16-bit colour depth, only 5 bits are used for each of red/green/blue, and thus a colour that cannot be exactly expressed in 5 bits will be rounded to the nearest colour.

Warning - although setting individual pixels is reasonably fast, if you need to set a lot (for example, to draw a line or a box), it would be much faster to use the appropriate dedicated function (such as WindowLine). This is because to draw boxes and lines, especially large ones, or filled ones, would take many, many calls to WindowSetPixel to achieve the same result.

Note: Available in version 4.36 onwards.

Lua example
for x = 1, 360 do
  local y = math.sin (math.rad (x)) * 100
  WindowSetPixel (win, x, y + 120, 0xFF0000)
end -- for
Returns eNoSuchWindow - no such miniwindow

eOK - success
