How to make a physic object follow the mouse and collide properly?

[SergioAndre]

Hi all!

I'm trying to make an object (with physics) follow the mouse, like the Mallet of an airhockey game. I tried but it is not like I want, the collisions are not accurate and sometimes the Mallet passes over the Puck without colliding.

It seems simple to do but so far I could not make it work properly.



I am using the "physics - engine" object and the "Physics - Bouncing ball movement" for the puck.

My idea is to make an air hockey game using physics, so that the movement of the Puck is more natural and accurate.


I appreciate any help.

i am guessing that when the mouse feeds its coordinates to the pc at the mouse-driver level, it can jump from 1 position to the next without all the numbers in between, which is why it moves so fast. so if you move mouse fast, and it goes from 60 to 200 in ONE step, and the puck is at 100, it misses.
i am only starting out, but i guess you would have to have self-coded "mallet_x" and "mallet_y" variables that change BASED on how far the mouse has moved (ie comparing "mouse_position_now" with "mouse_position_before", however long before is!) , so that a slow actual mouse movement will change mallet_x and mallet_y by +-1 pixel (?) and a fast movement (ie 60 to 200) will move it by +-5 pixels (or whatever maximum number doesn't skip over (the middle of?) the puck)
so there is a bi more to calculate (especially to see where the mouse was, where is it now)
hope that helps
