Use at your own risk.

The Bos to Lua conversion page is incomplete.

The Bos to Lua conversion page can and will create bad code.
Using a low level hierarchy to parse a higher level hierarchy is not correct.
Do not look directly at the Bos to Lua conversion page.

That is pretty nifty. One question, though- I thought that Lua didn't handle move / turn / spin the same way as BOS. Has that been fixed? I see the numbers are the same, so I'm presuming yes.

I don't see anything else that's really sticking out there that can't be addressed with minor bug-fixes (on the modder's part, and gee, we only have to do it once).

Oops I didn't read the disclaimer, how many hours do I have left to live?

How easy would a batch bos -> lua conversion page be to create?

Hmm. Needs to handle long lines. Quotes cause major problems.

And includes don't get converted.

None of this is the end of the world, just noting bugs.

There;s a bug with function conversion
cob: CALL-SCRIPT scriptName();
lua: CALL-SCRIPT scriptName()

Functions should be localised by default. Also "get" in cob is could be converted to a lua function equivalent.

Another bug, local variables are still declared as "var myVariable" in lua instead of "local myVariable".

Another strange bug:
COB
Code:
         turn rshoulder to x-axis <70> speed <135>;
         turn rshoulder to y-axis <15> speed <270>;
         turn rforearm to x-axis <-40> speed <270>;
         turn lshoulder to x-axis <-20> speed <135>;
         turn lshoulder to y-axis <-15> speed <270>;
         turn lforearm to x-axis <-40> speed <270>;
         Turn rshin to x-axis <85> speed<540>;   
         Turn rthigh to x-axis <-100> speed<270>;
         Turn lthigh to x-axis <30> speed<270>;
         Turn chest to y-axis <20> speed <90>;   
         wait-for-move hips along y-axis;      
         move hips to y-axis [1.2] speed <8400>;
         wait-for-move hips along y-axis;
         turn rshin to x-axis <10> speed <630>;
         move hips to y-axis [0] speed <8400>;

LUA
Code:
         Turn( rshoulder , x_axis, math.rad(70), 135 )
         Turn( rshoulder , y_axis, math.rad(15), 270 )
         Turn( rforearm , x_axis, math.rad(-40), 270 )
         Turn( lshoulder , x_axis, math.rad(-20), 135 )
         Turn( lshoulder , y_axis, math.rad(-15), 270 )
         Turn( lforearm , x_axis, math.rad(-40), 270 )
         Turn rshin to x-axis <85> speed<540>   
         Turn rthigh to x-axis <-100> speed<270>
         Turn lthigh to x-axis <30> speed<270>
         Turn chest to y-axis <20> speed <90>   
         wait-for-move hips along y-axis      
         Move( hips , y_axis, 1.2 , 8400 )
         wait-for-move hips along y-axis
         Turn( rshin , x_axis, math.rad(10), 630 )
         Move( hips , y_axis, 0 , 8400 )

It may be due to a multi line piece definition when copied into the cob window.

math.rad should be localized as well. Or we need an equivalent to STANDARD_COMMANDS.h that is auto-included.

Oh, and...

Move( hips , y_axis, 1.2 , 8400 )

Will have some funny results ;)

If the move / turn / spin distance / radius / velocity is not enclosed in brackets, it's a raw number, and it needs to be converted to float by dividing by the correct constant for linear / angular.

Do not submerge the Bos to Lua conversion page in water, even partially.

Even if it doesn't give out a complete script, if it can get most of the leg work out of the way, I'm all for it.

Yes, is it like Happy Fun Ball or the Aperture Science Portal device? Who knows?

Thanks for buggy examples, I'll try to fix them later today.

Another bug, local variables are still declared as "var myVariable" in lua instead of "local myVariable".

Both these things (call-script and var) should work. If they are not working for you, paste me an example (like you did with your other post).

The Bos to Lua page is in no way affiliated to the production of lua . In the event that lua is outputted, the result is to be disregarded immediately.

Staring at the bos to Lua conversion page has been known in some rare cases to cause pregnancies. If you experience a burning sensation while using the bos to Lua conversion page, please stop usage immediately and consult your physician.

translation of the above:

bos -> lua conversion isn't fully functional.



...isn't it?
