Let's start off by looking at how we can give our player character a slippery obstacle to avoid (or use wisely).
For this tutorial you will need to open up the snapshot
If you don't have it already, head to the Loading Screech Downloads page and click on <5 Min BASIC ZX which contains the snapshot.
Once you have opened up the snapshot navigate in AGD
to Events > Player control (type 0).
Now scroll down to the segment of code that says;
LET IMAGE = 7
IF X > 159
LET X = 52
What all of that means is;
"If the player sprite touches a
custom block, make the player look like image 7, animate the player sprite."
"If the player can go down without obstructions, move the
sprite down the screen and make a beeper sound."
"If the player goes past X 159 then move down to the next
screen, starting at X = 52" (AGD uses X for up down instead
1. Change SPRITEDOWN (not SCREENDOWN) to SPRITEUP.
Run the program and see what happens.
2. Now change SPRITEDOWN to SPRITERIGHT and run
the program again.
3. Change LET IMAGE = 7 to any other number
e.g. LET IMAGE = 5.(as long as that number image exists).
