Weird compiling error with a defined bit in a conditional statement

[Sprybug]

Hey guys, as you know I'm working on Robot Zed and decided to use DIMs and DEFs to help keep my code readable and keep my sanity, however I came across something weird.

 

I dim'd all my variables with names, and for bits, I used DEF like you are supposed to.

 

For example I have:

dim Extra_Bits = g

 

Then I have underneath all my dims:

def Enemy_Direction = Extra_Bits{0}

def Ball_Direction = Extra_Bits{1}

def Missile_Direction = Extra_Bits{2}

def Section_Exit = Extra_Bits{3}

def Section_Order = Extra_Bits{4}

def Genesis_Controller = Extra_Bits{7}

Now this is fine, however in a conditional check on one of these it would error on compile.

The line before it is fine:

if Section_Order && Level_Section=6 then Level_Section=0:goto LS2

But the line after it gives me a compile error without a reason

if !Section_Order && !Level_Section then Level_Section=6:goto LS2

I tried changing it to: if Section_Order=0 && Level_Section=0 and it still error'd on compile.

So, I tried changing Section_Order in this line to Extra_Bits{4} and it compiled no problem, so now that line is:

if !Extra_Bits{4} && !Level_Section then Level_Section=6:goto LS2

That's fine apparently. So, is there a bug here in the compiler? I can't see any reason why this would happen.

Try leaving out the "def"

I always get invalid keyword errors reported when I have have bits dim'd, but compiles ok.

 

This works for me:

 

dim animplayer1 = var18
dim animplayer2 = var18

animplayer1{1} = 0
animplayer2{2}=0

Oh , had to re-read your post again. you are wanting to use def . sorry Sprybug!

What compile error did you get specifically?

 

RT has a note about running into odd problems using different defs, so I have a them. Instead, you can put the number of the intended bit in the dim statement as a way to remember, e.g.:

 

dim Enemy_Direction_Bit1 = g

dim Ball_Direction_Bit2 = g

(etc)

 

It's not as clean as a def, but it works.

Thanks guys for the heads up. I might just keep it the way it is for now then. It should work logically, but making it a not bit check (or just a check for 0) for some reason causes it to not know what to do. It would come back with a Syntax Error on that line and would show me the entire compiled code without indication there what went wrong. That's about all I can really tell you.

this compiles

 

 

 
 dim Level_Section = z
 
 dim Extra_Bits = g
 
 dim abcdefg = g
 
 def Enemy_Direction = Extra_Bits{0}
 def Ball_Direction = Extra_Bits{1}
 def Missile_Direction = Extra_Bits{2}
 def Section_Exit = Extra_Bits{3}
 def Section_Order = Extra_Bits{4}
 def !SectionOrder = !Extra_Bits{4}
 def am = a{4}
 
 if !Level_Section && !Section_Order then Level_Section=6:goto LS2
 
 if !SectionOrder && !Level_Section then Level_Section=6:goto LS2
 
 
 
 
LS2

I see what you did there! So I have to make defs for both True and false bits on conditional checks? That seems like quite a bit of work.
