Any idea how I use jit.anim.drive to control the scale (I want to make something pulsate) and jit.phys.body to control the position on rotation of a gridshape?

By setting the @targetname , we don't have to connect directly to the controlled object. Then you can filter the messages coming from jit.anim.drive and send them where you want. HTH

also, if you set @send_scale 1 on your phys.body, you only need to send the scale values to the phys.body, and they will propagate to the gl.gridshape.

Cheers yeah, I unset it because having the gridshape receive scale from both phys and anim understandably made jitter angry.

Something's still not right, I can use jit.anim to make both the phys and the gridshapes change their scales but when I try to move the phys object with an impulse message it moves for a tiny bit then stops.

simple rigid-body shapes don't like to be scaled. the engine basically recreates the collision shape everytime you adjust the scale. thus the forces are not working.

however, convex-hull shapes don't have this problem. so you can achieve this effect by doing the following:
