| - | One major change is that there is no actual Stage (Scratch 1.4) or Background (Scratch 2). So if you want a background image you create a big costume (GP screen size is 800 x 600 unlike Scratch’s 480×360) and just don’t move it around | + | === Stage/Background === |

| - | I have converted all the Scratch 1.4 images to .png and re-sized the background ones to be 800×500. The zipped file of these images is available here. I believe the Scratch Creative Commons Attribution-ShareAlike 2.0 license allows them to be used in GP but if anyone knows differently, please let me know | + | Simon Walters has converted all the Scratch 1.4 images to .png and re-sized the background ones to be 800×500.

| + | |||
| + | === Timer === | ||
| + | |||
| + | The timer counts up in milliiseconds (thousanths of seconds) and there is no reset timer block. So you have to set a variable, say starttime, to timer value and then subtract the timer from your starttime and divide it by 1000 to get the time difference in seconds. | ||
