I've figured out how to rotate my model at its torso but I can't figure out how to limit it's rotation. If the rotation was between 0 and 80 it wouldn't be a problem you could just use

+ Code Snippet

 if rotx>0 and rotx<80

and then add some code to wrap the value within that. But my problem is that the rotation is from 313 wrapped around to 0 then to 80. If that didn't make sense then I mean this:
313 - 360 and 0 - 80.
I had tried subtracting 360 from 313 but that doesn't work.

+ Code Snippet

    if limb angle x(1,24)<80 and limb angle x(1,24)-360>-47
    	rotate limb 1,24, wrapvalue(mousex()),0,0
    else

With the given code it should get to 80 one way and stop or got to 313 and stop. I haven't worked out the code to adjust the limb so that it doesn't freeze in place yet.

But the code never executes the rotate limb command. The limb's x rotate stays at 0.

I have a feeling I'm totally missing the boat.

Go ahead. Walk into Mordor.

What about if you put:

if rotx<-47 then xxxx
if rotx>47 then xxxx

Cheers.

No go.. Heres the entire source if it helps. There isn't a lot going on. Any model with an FPSC skeleton should work.

+ Code Snippet

load image "civilianmale_d2.dds",1
load object "civilianmale.x",1
texture object 1,1
position object 1,0,-20,0
set object speed 1,5
loop object 1,988,1012


do
    text 0,0,str$(screen fps())
    text 0,10,str$(limb angle X(1,24))
    text 0,20,str$(limb angle Y(1,24))
    //313  51
    if limb angle x(1,24)<80 and limb angle x(1,24)-360>-43
    	rotate limb 1,24, wrapvalue(mousex()),0,0
    else
    	rotate limb 1,24,0,0,0
  	endif
  	

    remstart
    if limb angle x(1,24)-360>-47
    	rotate limb 1,24, limb angle x(1,24)+2, limb angle y(1,24),limb angle z(1,24)
	endif
	if limb angle x(1,24)>51
    	rotate limb 1,24, limb angle x(1,24)+2, limb angle y(1,24),limb angle z(1,24)
	endif
	remend
 	
    control camera using arrowkeys 0,3,3
	sync
loop

Go ahead. Walk into Mordor.

So you are trying to control your object with the mouse ?

Have you tried instead of:

rotate limb 1,24, wrapvalue(mousex()),0,0

with:

rotate limb 1,24, wrapvalue(mousemovex()),0,0

Cheers.

I had forgotten about that command! That line of code really doesn't work it has to be changed to this

+ Code Snippet

rotate limb 1,24, wrapvalue(limb angle x(1,24)+mousemovex()),0,0

Which is a lot smoother than using mousex() and will probably help me limit the angle better. Thanks!

Go ahead. Walk into Mordor.

My topic is already on top of the list so if I bump it's not very far.
I got the code working awesomely so I'm going to share it for anyone who needs it. This will work one any model with an FPSC skeleton for sure and if you need a different limb change 24 to whatever you need.

+ Code Snippet

 movex=mousemovex()
    if movex>10
    	movex=10
    endif
    if movex<-10
    	movex=-10
    endif
    if limb angle x(1,24)>-46 and limb angle x(1,24)<46 
    	rotate limb 1,24, limb angle x(1,24)+movex,0,0
    endif
    
    if limb angle x(1,24)>44
    	rotate limb 1,24, limb angle x(1,24)-1,0,0
    endif
    
   	if limb angle x(1,24)<-44
   		rotate limb 1,24, limb angle x(1,24)+1,0,0
   	endif

The first part of the code is to limit movex which stores the mousemovex value. If you don't do this and suddenly move you mouse really far from it's starting position your models torso will jump around.

Go ahead. Walk into Mordor.
