Help (Matrices ) - Pushing a Block

We're glad you came by, but you might find what you're looking for elsewhere. TI-Basic Developer is not the site it once was. While its information on commands and other calculator features remains almost second-to-none, its forum, archives, and even hosting service, Wikidot, have been decaying for years. The calculator community would love to see what you're working on, or help you in your next coding adventure, but TI-Basic Developer is no longer the place to do it. Instead, you should head over to Cemetech (primarily American) or TI-Planet (primarily international). Both are active, well-established forums with their own archives, chatrooms, reference material, and abundant coding tools and resources. We'll see you there, we hope.

Summary:

Need some help with a game I'm making. I have the right idea, just I can't figure out why there is an "ERROR: INVALID DIM" message.

Help (Matrices ) - Pushing a Block

Okay, the game uses the [A] matrix and each level a new component is added (for instance, the first level all you have to do is move a "+" to the "*", but later on there are "O"s that you can't step on, walls (Xs), trigger switches that turn certain "O"s on or off, teleport spaces, and now I'm trying to add in blocks that you can push. I'm setting the blocks that you can push to "10" spaces (Walls are one). G=the Getkey. A,B is the location of the +, and the matrix is an 8 by 16. My calculator is an old TI-82 one (it got rented to me for school).

So, this is the part I need help on. The first line, last part is the part that gets the error. (I know its not optimized):

:If G=26 and [A](A,B+(B<15)=10 and abs ([A](A,B+2(B<15))-5.5)≠4.5:Then
:10→[A](A,B+2):0→[A](A,B+1)
:Output(A,B+1," B
:End

This gets repeated with minor changes to account for moving up/down and moving left.

It looks like you are missing a parentheses — [A](A,B+(B<15))=10. Just out of curiosity, what game is this from?

Before I forget, Welcome to TI-Basic Developer!

I made the game up, so its not on this Wiki. I might take the time to do it later.

But thanks. Just like me to make an obvious mistake like that and not be able to catch it. >_<.
