I have been tring to get a return value for and object or limb's x,y,and z angles (in world OR object relativity).
x and y axis return values; y is good, x is inacurate.
Z onle EVER returns zero.

this is the same for both getting limb and object angles using:
"returnvalue=object angle z(obj no#)"
"returnvalue=limb angle z(obj no#)"

I've tried using "ATANFull" which does return angle values for Z axis, but I am still reading it as inacurate.

Using a "light" pos'd @ 1 limb and "POINTING" to another limb has does return angle values which I had to convert into 0 to 360'.
I was hoping to use my lights for other things....

I want to know: if anybody else has the same problem with get'n/returning Zaxis Angles for object or limb?
or not?
I'm sort of reling on it; else I have to compromise.
I like DB so far; and would appreciate your input.

works fine for me for objects.....and for limbs..... so don't know whats wrong for u, can u post some code?

just noticed

Quote: ""returnvalue=limb angle z(obj no#)""

, that should actually read;
"returnvalue=limb angle z(obj no#, limb no#)"
but i don't think that's your problem, um are you sure the limb isn't meant to read 0? have you tried "rotate limb obj #,limb #, x,y,z" and then reading the value of z?

life's one big game

The limb angles are the relative angles to it's parent limb. If you have a gun, linked to the player's hand and rotate the limb 90 degrees. It will be turned 90 degrees relative to the hand.
If your limb hasn't a parent limb, the limb parent would be the object itself.

If you want world angles, use limb direction x/y/z(objnr, limbnr).

If it still doesn't work, it has to be something with your code or the structure of your object.

you probably know this... but if you havn't specifically rotated the object on it's z axis, then your z angle will always be zero

by pointing an object, it does not change the z angle of an object. try this:

+ Code Snippet

sync on
make object cube 1,2
position camera 10,2,0
point camera 0,0,0

do
zrotate object 1,object angle z(1)+1
text 10,10,"object rotation z: "+str$(wrapvalue(object angle z(1)))
sync
loop

works fine for me...
