I’m getting some weird results in my particle physics, and I’m sure it’s all just my fault, but I wanted to check. Please tell me if I’m wrong about any of these!!
Panda physics uses mks units for distance/mass/time (velocity is m/s, forces are all in Newtons, torques in N*m)
Setting a force to be mass-independent makes it an acceleration
The radius of a LinearDistanceForce is just a coefficient whose inverse square gets applied to the force
Masses are measured in kilograms
Wait, LinearDistanceForce doesn’t detect the distance to the body it’s affecting??
I thought the dynamic was that I just plop it down at a position and it affects everything based on its actual position from every body it’s attached to and your falloff type, is that wrong?
The quantity in question is the float r in the constructor for a LinearSinkForce:
panda3d.org/reference/1.9.1/ … rSinkForce
oh, i read it again. radius should mean the max distance that the force source can affect. so your statement in 1st post should be correct.
