Space it out, and it becomes more apparent. There are multiple issues with the nesting of your conditions, as well as semicolons.
Code:
//check if there is rotation in Z
if(R_FK_Shoulder_CTRL.rotateZ != 0)
{
// if there is rotation in Z, check if there is rotation in X
if(R_FK_Shoulder_CTRL.rotateX !=0)
{
//if there is rotation in X after Z, then ik handle roll = rotateX / -2
AO_R_BendArm_ikHandle01.Roll = R_FK_Shoulder_CTRL.rotateX /-2
}
// if there is no Rotation in X after Z, then Roll = 0
else
{
AO_R_BendArm_ikHandle01.Roll = 0
}
}
// if there was no rotation in Z in the first place, check if there is rotation in Y
else
{
if(R_FK_Shoulder_CTRL.rotateY != 0)
{
// if there is Rotation in Y, check if there is Rotation in Z after Y
if(R_FK_Shoulder_CTRL.rotateZ != 0) ;
// if there is Rotation in Z after Y, Roll = rotateZ / -2
AO_R_BendArm_ikHandle01.Roll = R_FK_Shoulder_CTRL.rotateZ /-2;
// if there is no Rotation in Z after Y, Roll = 0
else
{
AO_R_BendArm_ikHandle01.Roll = 0
}
};
// if there was no Rotation in Y in the first place, Roll = 0
else
{
AO_R_BendArm_ikHandle01.Roll = 0
};
}
Imagination is more important than knowledge.
