I’m not sure if I understand your question correctly (and also this comment is a half a year old) but I think you want a pendulum that won’t collide with anything else (?) if that’s what you want, you can just turn off all collisions on it by: Right clicking > Collision layers > Uncheck all & Collides with water = false

@@Adamimoka Not exactly. Was looking for making a pendulum swing left and right constantly regardless of what's colliding with it (like it's so heavy that anything that hits it wouldn't set it off course or nudge it a bit in any way and it would continue to swing, so collisions would still be on) Even for a late response, appreciate it nonetheless!

@@MajorTom77 Oh ok, well to do that all you have to do is set the weight to infinity. As long as nothing immovable is in its way, it will not slow down, also make sure air resistance is off or else is will lose speed that way.

@Galaxy you can modify the mass of an object by selecting an object then clicking one of the buttons default on the top-right of your screen. I don’t remember exactly which one, and I don’t use Algodoo anymore, but you should be able to find it.

look he quit doing algodoo
