Hi, I recently had a similar problem which I was able to solve with a fairly simple change in SimulationIslandSimulator.cs. Essentially, I added "bool IsAlwaysDeactivationCandidate" which is checked in UpdateDeactivationCandidacy and causes the instance to disregard velocity and timeouts w...

I just wanted to officially add my game "Thunder Moon" to this list because it's finally in peer review on XBLIG! Thank you Norbo, very much, for making your work available to low budget indie devs such as myself. Out of respect for your time I've done my best to resolve the many challenge...

Oh shoot, you are right of course. I was looking for/expecting logic along the lines of "if(connectionA == null)" to be scattered everywhere and I never noticed that logic in the property setters which of course makes perfect sense. Thanks for pointing that out. BTW adjusting the angular v...

Thanks Norbo. I'll start with manipulating the angular velocities. I expect it will do the trick. It would be nice if there were a constraint or motor suited for this problem but I don't mind a manual solution. Whatever works! Incidentally, I had been peeking around in various constraint classes loo...

Hi, I have a situation where a flying character is moving around under the influence of a linear motor and an angular motor. Sometimes, when the goal direction changes dramatically, the character will flip over as it orients to the goal. I'd like the NPC to not do this, and I am still trying to figu...

Thanks very much for the detailed & helpful reply, as usual. I'll look into initializing the entity directly, that seems most likely to help performance based on your comments.

Interesting, thanks for the explanation. If I understand correctly, it seems like it might be preferred for kinematic CompoundBody objects to use a separate CompoundShape ctor that didn't need to ComputeCenter or adjust the local position? Not that it's a big deal but I'm always looking for ways to ...

I was providing a list of zero mass shapes to a CompoundBody ctor and the ComputeCenter failed validation because of the zero mass total of all shapes caused a divide by zero. Note that I am using the CompoundBody ctor that doesn't take mass, which the XML docs say is the way to create a kinematic C...

Makes sense, thanks for letting me know. Now I need to go learn how to hook my branch to a different fork

It may be something I'm doing wrong, but when I try to use TortoiseHg to check for incoming changes it gives me an "HTTP Error: 500 (URL Rewrite Module Error.)" message. The log shows this: % hg --repository C:\code\bepu\development incoming --quiet --bundle c:\users\localuser\appdata\loca...

Thanks!

Also I was wondering, it seems like it would make sense for the Matrix.Validate methods to use the Vector.Validate for each of the axes since they will typically (always?) be used for transform math that would rely on the LengthSquared() being in range. It also seems likely the LengthSquared of each...

Hi Norbo, I recently had a problem that was due to my own error, but to find the cause I wound up adding some more validation to the CompoundShapeEntry which you may want to consider keeping around. The first type is the validation of the transforms provided to the ctors. Higher level code had been ...

Thanks Norbo, that makes sense to me. I appreciate your time as always!

Thanks for the explanation. As for providing a repro, this seems to be a pretty rare thing to have happen. I only seem to get it after hours of heavy load testing, and unpredictably at that, because I haven't yet been able to figure out the inputs that cause the problem. I will try to get more infor...
