Like I said in my earlier post, that can actually slow the game down, if you use a lot of them, since it has to do all the calculations every loop...

Yeah I tried to optimize my TBS engine with those, and it ended up running at almost exactly the same speed. Booleans are faster than If:Then only if you don't have extremely complicated movement routines.

Yes, I meant exactly that.
I don't think my games are slowed by it that much, I only use it for moving left/right/up/down.

Ok, good. I had to try to guess at what you meant. I have a few of those in my game but, like tifreak8x said, if you use to many of them, they can do more harm than good.

I would love for an assembly coder to go in CalcSys or a debugger and see exactly how many clock cycles each of these commands takes and make a table, then we could just add up the cpu time required by each command in a routine to see which is faster.

ok, today in math class, had a lot of time so did some testing on speed of stuff.here's wat i got
-(everyone except me probably knew this, but ANS work faster than the number)
-Using the real number instead of variable works faster, real(0 will work faster than real(A

Sweet. I never knew about the Ans thing. For the number faster than variable, it makes sense. Instead of having to search the VAT for the variable to get the value, it has the value provided for it immediately. Still good to know though.

Using ans is alright, but if you are doing any other equations, ans will be messed up.
Basically, ans is good for simple things (I use it for a program that has multiple routines, I just store the number to ans, call the program, then the first line in the program is Ans->L
That makes things a little smaller and faster...

If you want to save a byte do

-->
CODE
ec11
real(0
If not(Ans:Pause "Install Xlib!
If not(Ans:Returnc2
ec2
Doesn't save much but hey 1 byte is a byte!

Check the code, it produces different results. Necro's produces 1, where yours produces 0.

yes, you unrapped a line break and as such, "not(...:not(..." is better than an "not(Ans:"...if I had a third line of conditionals in there, it would be better my way though
