What makes this rock bounce up?

Recommended Posts

Hello!!  

 

Thanks for your eyes.

 

Please watch this video from 1:18 until 2:52.  I know it is a little long but in it I explore something weird I found in the game Unmechanical that I would love to see if anyone on this website understands.

It looks like just a bug. That's not only the ground, it's more like a vulcan, there's probably some collision detection doing weird things.

 

Or maybe, since it's a vulcan and fireballs are coming out, hot air may be coming out all the time, making the rock move a little.

 

Anyway, it looks more like a bug, probably they have a box there that applies a force to anything that's inside to make the fireballs fly, and when you put another object the same force is applied.

You know, you remind me of that guy on YouTube, who was complaining that water in real life doesn't behave the way it does in Minecraft. Is this a trend on YouTube now, or something?

See the rocks coming out? They're appearing just above the exit. The force pushing the rocks that appear is the same one pushing rocks that are dropped near it. If the rocks existed low enough they were actually coming out the collision detection would need extra programming, so it was a matter of time constraint while designing how it worked.

Collision box probably doesn't fit the mesh?

If its an uneven col (not a box) it's possible that its trying to fit in. The vector moves the rock closer, but the rock finds itself squeezed in a tight collision. Assuming the material is a bit bouncy (as opposed to an actual rock), it's possible that its shape distorts and it then propels itself out as a reaction to the collision.

Pure assumption here, but it's something I've dealt with myself in Unity, so I wouldn't be surprised.

 

Alternatively, two different hit-shapes on the same objects that could interact with said uneven collision independently.

Sorry for going off topic and I don't mean to offend you or anything - I'm just curious: do you have Asperger's?

 

What's that even based on?

Thank you so much for all your answers.  It makes me so happy that there is such a vibrant community of people out there who are willing to take time out of their day to help spread their knowledge.  Your input has helped me understand certain aspects of game development and will undoubtedly help anyone who sees this thread understand how to make a game even a little bit better.  Making a good game is possible alone but for me it is much more enjoyable with a community.

 

As I continued to play the game there was a point when I could drop an object into a similar opening that had a collision agent attached.  Your information helped me better understand what was going on.  It would be so cool if we could combine our knowledge and solve even more difficult problems.

 

Anyways, I appreciate your help.

 

Good Day!!!
