How do I negotiate collisions between two colliders?

Question

I have two collider gameobjects each driven by a player. When the two objects collide I want to keep score of each, like bumper cars. Naturally only one can register a hit in the current collision detect. But the counter quickly gets out of hand or the counts are off, like noisy or switch bounce. I am using OnCollisionEnter. I am even using velocity compares but this isnt working correctly either. I have not found any collision hierarchy logic or collision predominance logic to implement. It all starts with two active colliders. When they meet the code executes for both and they both win a point. But I am aiming for only one to win the collision point. Thank you in advance.

There are some conditions when a player gets a point and the other not, I think? These conditions you have to implement for example in the OnCollisionEnter function, because Unity doesnt know the rules of your game.

Yes. But there has to be a way to negotiate, prioritize, arbitrate, and mediate. When two colliders hit there is a cacophony of events. Oh and because velocity and thrust are still on too. Each shows an impact. And because the code sits in two onCollisionsEnter, one for each object it is attached to? I have to assess a hierarchy of design parameters. So I must catch the first one then ignore all the rest and that would be in a time frame, acceptance window or till some other event? Hmmm. I see what you are saying and this has caused me to slice this problem to a greater degree of granularity. I must dissect and pursue this dilemma further. I must be missing part of the total situation then. I should have delved into this sooner before my project became larger. This is one of those 'Walk aways' where I must extract myself from the problem to see a clearing. This is definitely all 'Bumped up'. I am open to any more suggestions. Or how anybody has solved this because this is definitely a multiplayer concern.

Well now. I had an epiphany and went into the realm of '$$anonymous$$ultiplayer collision management'. O$$anonymous$$G what an open pit of decisions and assessments one has to make. I thought is was an easy task of just adding a collision detection to a gameobject. This merely opens up the bottomless pit of agony. I must now dig further in and attain new levels of knowledge to circumvent my current apoplexy. Wish me luck. It looks like its going to get ugly. The sirens of the dark abyss are calling out and seducing me into the void.

It all boils down to arbitration hierarchy...

I don't see why that "has to be" something that you can implement in a way other than via adding your own logic to make the decision. I wouldn't expect that.

I totally agree with you on this. I am also looking at this from a perspective of using Bolt graphical design too. After adding detection collision to a project is when the real design comes to play. In my one piece of collision detection handler code I went down the path of identifying what triggered the collision. Was it player 1 or player 2. Well that doesn't work as the first tag is always first because both colliders see the collision. Also this is not a networked situation yet. A player can a be human and the other is AI or vice versa. $$anonymous$$y thinking now is the same piece of code with two public gameobjects in the inspector. I then assign the two GOs in one order for player one then in player two I reverse the assignments. That way I can use the instantiation to start the control logic. But this could be the long way around the park also.
