Hi Tulamide, I like the your deceleration control, this is an interesting feature I hadn't thought about. I also like Uberlou's method by way of increasing the distance the mouse pointer has to move away from the sprite before the sprite will start to follow the mouse. This will help reduce 'slight' or unwanted mouse gestures, whereas, 'purposeful' or long mouse movement is key to the control system I want to achieve.
Happy days, thank you both again!
