Description

The DrawPointer function draws a red pointer on the display. There can only be one pointer at a time on each station.

Arguments

• Integer:
  This integer is the display index where the pointer should be drawn.
• Table:
  This key-value table must have 'x' and 'y' keys with values indicating a position on the display. See the example below.
• Integer (optional):
  This optional integer defines a duration for the pointer in milliseconds. It fades out. If a duration is not set, then it stays visible.

Return

This function does not return anything.

Example

This example draws a pointer on display 1 for 5 seconds:

return function()
    --Set a display index
    local displayIndex = 1
    --Create and set the position in a table
    local position = {}
    position.x = 150
    position.y = 25
    --Set a 5 seconds duration - in milliseconds
    local duration = 5000
    --Draw the actual pointer
    DrawPointer(displayIndex,position,duration)
end
