# TileImage handle,[x],[y],[frames]

# Parameters

handle= variable holding the image's handle x=starting x location of the tile; assumed 0 y=starting y location of the tile; assumed 0 frames=the frame of the image to tile; optional with imagestrip

# Description

If you want to make a starfield or other easy tiled background, this is YOUR command. All you have to do is specify the image handle (an image loaded with the LoadImage or LoadAnimImage command). Optionally, you can specify a starting x and y location, as well as an optional frame. You can milk some serious parallax effects with a simple imagestrip with a couple of various starfields and the TileImage command.

# Example

; CreateImage/TileImage/ImageBuffer example
; Again, we'll use globals even tho we don't need them here
; One variable for the graphic we'll create, one for a timer
Global gfxStarfield, tmrScreen
; Declare graphic mode
Graphics 640,480,16
; Create a blank image that is 320 pixels wide and 32 high with 10 frames of 32x32
gfxStarfield=CreateImage(32,32,10)
; loop through each frame of the graphic we just made
For t = 0 To 9
; Set the drawing buffer to the graphic frame so we can write on it
SetBuffer ImageBuffer(gfxStarfield,t)
; put 50 stars in the frame at random locations
For y = 1 To 50
Plot Rnd(32),Rnd(32)
Next
Next
; Double buffer mode for smooth screen drawing
SetBuffer BackBuffer()
; Loop until ESC is pressed
While Not KeyHit(1)
; Only update the screen every 300 milliseconds. Change 300 for faster or
; slower screen updates
If MilliSecs() > tmrScreen+300 Then
Cls ; clear the screen
; Tile the screen with a random frame from our new graphic starting at
; x=0 and y=0 location.
TileImage gfxStarfield,0,0,Rnd(9)
Flip ; Flip the screen into view
tmrScreen=MilliSecs() ; reset the time
End If
