*code*

Having problems with this, still kindof new at it... Could anyone tell me whats wrong with it?

Basicaly, when port 0 has the value of 1, it's supposed to jump to label z, Which is then supposed to keep port 1 at value 1, but go on like a for loop timer until ecx is greater than 100 (timer), but while it is less than 100 it will keep port 2 at 1, and port3 at 0 and turn both to 0 when it's greater. Apon being greater, it will jump to linetwo and start a similar timer loop but with different port2 and 3 values.

I hope this wasn't too confusing... And I realize my code is probably way off.[/b]

After you jump to linetwo your program ends execution, there is no jump back to main loop, probably that is the problem?

Very nice indeed, very intuitive editor too!

Well anyway, I noticed the command that waits for input... would it be possible to have a similar one that syncs output with the other components (I'm guessing it would be to stop until next Think())? As it is now the other components cannot read fast enough and they have no output that tell when they are done either (or perhaps they will do either in the future?). A wait function would be nice too, although I'm guessing it could be problematic to implement.

A branch instruction and everything that goes with it would be a welcome addition too, should be fairly simple to do.

Btw, I also noticed that it doesn't like negative values "-1.0" becomes invalid label or something like that. (ENT:ValidNumber)

Very nice addition and very good work!

(Btw, you probably already know this, but you could speed up the execution pretty much by trying to remove all those consequtive IFs, either by having a "divide and conquer" strategy for them or doing some smart stuff with meta-tables (switch does not exist in Lua i believe), this would effectively change them from O(n) to O(logn) or even O(1) which is a very good difference as there is so little logic in each... perhaps it would be possible to turn all opcodes into functions instead, making extensions very easy, and everything O(1)... well just my five cents)

(EDIT: ah damn, this was meant to be in the original thread and not the documentation)

Again, what's this GPU you speak of?

Sounds mucho awesome, would love to have some juicy details

Well, no... because line is a timer that also is moving something along it's X-axis... The thing isn't even moving... so that part of the code shouldn't matter

It does not take much time to execute that, you won't need speeds that high.
I will fix -1.0 in next release.

To sync outputs you can attach timer to some port, enable timer via power button, and then just use halt 7; (it will pause right for the time needed to process wire data)

How dose the 'and' opcode work? I am slightly confused

[Black Phoenix]

Right now its logical, i.e. IF (A > 0) AND (B > 0) THEN A = 1 ELSE A = 0
