This example script uses preloaded images to improve the UI speed when the user hits a key on the

keyboard. As soon as the keyboard is hit, then the display switches to the new image which has already

been preloaded. The only delay is if the key is hit whilst the image is pre-loading - as soon as the image is

loaded, it will then display.

i = CreateObject("roImagePlayer")

p = CreateObject("roMessagePort")

k = CreateObject("roKeyboard")

k.SetPort(p)

i.PreloadFile("one.bmp")

loop:

i.DisplayPreload()

i.PreloadFile("two.bmp")

wait(0,p)

i.DisplayPreload()

i.PreloadFile("one.bmp")

wait(0,p)

goto loop
