SOLVED Apply a step value in SetHandle function

Hi,

REAL MYOBJECT_HEIGHT { UNIT METER; CUSTOMGUI REALSLIDER; MIN 0; MAXSLIDER 200.0; STEP 20;}

I have an object that have a Description Resource element with "20" as STEP value and I want to apply the STEP value on the height value of the SetHandle() function

def SetHandle(self, op, handle_index, handle_position, info):

        handle_origin = HandleInfo()
        self.GetHandle(op, handle_index, handle_origin)
        
        data = op.GetDataInstance()
        if data is None or not self.handle:
            return 

        height      = data.GetFloat(c4d.LKC_KINOFLO_HEIGHT)

        value = (handle_position - handle_origin.position) * info.direction

        if handle_index == 0:
            op[c4d.MYOBJECT_HEIGHT] += value

Thanks.

Hi,

this is probably a question of taste, but to me your solution seems a bit complicated. A quantized value can be expressed just as quant_value = int(value / stride) * stride, where value and stride are floating point values. You can replace int with math.floor or math.ceil if you do not want to round to the closest neighbour, but always to the lower or higher neighbour.

I found something like this:

op[c4d.MYOBJECT_HEIGHT] += value
mod = op[c4d.MYOBJECT_HEIGHT] % 20
op[c4d.MYOBJECT_HEIGHT] = op[c4d.MYOBJECT_HEIGHT] if mod == 0 else (op[c4d.MYOBJECT_HEIGHT] - mod) + 20
