Could you use another variable for the two instances?

Well, I mean instead of using V twice, why not use W or something for one of them?

I sort-of understand... i think... maybe not...

So like this:

Game loop:
Move and stuff, uses W
Change W to V
Displays stuff and uses pxl-test stuff for variable V
End game loop:

Or would that even help fix the problem?

That might. Why do you need to change W to V?

Because V is what is used for pxl-testing. It is the output of pxl-test (Actually, the function I use is called isPixelSet, but, whatever)

Ah, I see, now. Well hopefully that code above helps you :)

So what are some other limitations and solutions?

EDIT: Yay! So the scrolling problem is fixed(Not sure if that was even a problem...). The problem was that the enemy would try to go up a hill, but it wouldn't work. So I still need that V and W update-thingy I asked a little earlier to get working. So, you can post in my thread in "Computer Projects and Ideas". My thread is about the game I am making that I needed help with. The topic is the one called something about my new NXT game about a square.

move collision checking to before moving player, but still in the game loop.

Edit: Argh: Page turn fail.

Here's one I'm not sure was brought up: pxl-test doesn't work on black stuff, so you'll need a mask for collision unless you border everything. In fact, it's better in many ways so that you can have passable black stuff and such, plus background images don't collide.

So instead of doing this:
Loop:
Move
Check collision
end loop

Do this:?

Loop
Collision checking
move
end loop

?

yes, because then you'll get the closest values possible for the move command itself.

hmm... ya maybe so.

Any other limitations and solutions?

Also, I am making a platformer that does use pxltest-like collision, so if you could help in any way, go ahead (please).  http://ourl.ca/15431

Well, looking over that it might be handy to have some form of basic compression, since most of your level data pics are blank space. You could save upwards of 50% space.
