Algodoo

i have one with 5k objects but it refuses to upload, and it keeps crashing, someone please help troubleshoot this nonsense

It's not "nonsense". It's called computer lag. In any physics simulation app like Algodoo, the motion and interaction of each object with other objects in the scene have to be calculated on-the-fly. That requires a fast computer. If your computer is old, or simply doesn't have the required hardware and software to handle many high speed calculations, the app will either "lag" (slow down) or in the worst case it will crash. 5K objects is a lot for even modern gaming computers. I suggest that you reduce the number of objects in the scene you are asking about. There are other ways to minimize lag but I'll save those suggestions if you still have problems after reducing the number of objects.

alright, i’ll make one with 3k objects instead and see how it goes, thanks

Awesome!
