Hi all,
I had make an animation of a dropping ball (normal ball) with the acceleration of 9.8 m/s^2 and initial velocity of 0 using MassFX in 3dmax before. Now I want to make a dropping ball (abnormal ball) with the acceleration of -9.8 m/s^2(the deceleration of 9.8 m/s^2) using 3dmax. The initial velocity of the abnormal ball is equal to the end velocity of the normal ball and it's direction is same with the normal ball. I had intended to do this by changing the Acceleration Value of Scene Settings in MassFX Tools dialog (changing the value 981 to -981). However, changing the Acceleration Value changes the motion direction of that ball unexpectedly and the minus seems to represent the direction of motion in Scene Settings of MassFX Tools dialog.
Do you know how to make an animation of a dropping ball with the acceleration of -9.8 m/s^2 (the deceleration of 9.8 m/s^2) using MassFX? I don’t whether I express my meaning clearly.
Any answers will be very appreciated.
Thank you!
Hi Po Ren,
You should be able to just reverse the acceleration curve of the object. Since acceleration in 3ds max is defined as change in position per frame, you can modify the acceleration (or the velocity of the object). If you do this and can modify the change of velocity, you can just reverse it to obtain a linear negative change of velocity. That is a deceleration of the object.
Good luck!
