I'll give it a shot thanks for the suggestion! I'll need to re-write these functions slightly but that isn't hard.

Edit - Works perfectly new functions....

stock ObjectRotateZ(Float:RX, Float:RY, Float:RZ, Float:rot_z, &Float:NewRX, &Float:NewRY, &Float:NewRZ)
{
	new
		Float:sinx,
		Float:siny,
		Float:sinz,
		Float:cosx,
		Float:cosy,
		Float:cosz;
		
    FloatConvertValue(RX, RY, RZ, sinx, siny, sinz, cosx, cosy, cosz);
    // Convert from one euler angle sequence (ZXY) to another and add the rotation
    FloatConvertValue(asin(cosx * cosy), atan2(sinx, cosx * siny) + rot_z, atan2(cosy * cosz * sinx - siny * sinz, cosz * siny - cosy * sinx * -sinz),
		sinx, siny, sinz, cosx, cosy, cosz);

    // Convert back to the original euler angle sequence and apply the new rotation to the object
    NewRX = asin(cosx * siny),
	NewRY = atan2(cosx * cosy, sinx),
	NewRZ = atan2(cosz * sinx * siny - cosy * sinz, cosy * cosz + sinx * siny * sinz);
    return 1;
}

stock FloatConvertValue(Float:rot_x, Float:rot_y, Float:rot_z, &Float:sinx, &Float:siny, &Float:sinz, &Float:cosx, &Float:cosy, &Float:cosz)
{
    sinx = floatsin(rot_x, degrees);
    siny = floatsin(rot_y, degrees);
    sinz = floatsin(rot_z, degrees);
    cosx = floatcos(rot_x, degrees);
    cosy = floatcos(rot_y, degrees);
    cosz = floatcos(rot_z, degrees);
    return 1;
}

Thanks again YJIET
