Title: Troubles with the Simple Tutorial
Post by: PrinceOfBrains on 2012-04-04, 02:17:38 PM
So...I'm a little embarassed to admit it, but I'm having some problems with the Simple Tutorial, included in the help file.

I'm almost positive I've done everything right. I followed the directions to the letter, up to when you're instructed to compile and run it for the first time. But when I do, my triangle's movement is all wonky. It just kind of...spins around the screen, without actually moving. I feel like it might have something to do with my placement of the sprite's rules; I have the hardest time keeping the 'if player is pressing up' rule from accidentally absorbing any of the rest of the rules, so my rules list is kinda funky looking, but that's the only thing I can think of. Did I program something wrong? Is this a known issue with the tutorial that I didn't catch before?

If you need more details about my program thus far, feel free to ask. Any and all help is appreciated, here.

The nesting of the rules is important, and is determined by whether you check the box for "End If/End While".  Double-check that at the root level of your player sprite, you have the following rules:

If you are missing any of those or have any other rules visible at the root level, let us know and maybe we can help you narrow down the source of the problem. If the nesting is wrong, it's likely because you are missing the End If/End While checkbox on some rule, or you have an extra one checked.

Okay - as soon as I'm back home I'll check that out. One question, though - should the Accelerate rule be nested within the 'pressing up' rule? I remember being kind of confused by that in the directions.

Yes, the up arrow is the only thing that makes the ship accelerate/move. Is there something more specific about that that is confusing?

Naaah, that actually solved my problem! I didn't have 'Accelerate' nested under the 'pushing up' rule, and that did solve my problem. I was probably just mis-reading the directions. Thanks for the help!
