Question Physics.Simulate; Inaccurate Trajectory Prediction

I'm trying to make a predicted trajectory line for a ball using a separate 'simulation' scene and Physics.Simulate to plot each point of a simulated ball instance with line renderer. The problem is, the predicted trajectory falls way short of the flight of the actual ball. I'm wondering whether it's because my projection line code is running from Update (or FixedUpdate, tried them both!), while the actual ball itself is triggered by the OnCollisionEnter method. Both the simulation ball and the actual ball are identical in their physics properties, I've checked that too. Can anyone give me an insight as to how the OnCollisionEnter method works, seeing as it doesn't have to be called from either Update or FixedUpdate?

 

You'd have to show your code. Properly done, it should work fine.

 

The whole script's a bit of a mess right now. I've been playing around with a lot of things, trying to get it to play how I would like it. I'll tidy it up a bit and then post it for you.

 

I would verify that's correct. As physics are just a mathematical calculation, so if "all" the same variables(scale, mass, drag, force applied, angular drag, etc...) are being equated, then the result should be the same. Unless real life, then air temp and wind speed do kinda mess with you, lol..

OnCollisionEnter is basically a "message" that get's broadcasted, so it's "update" get's run from further up the line. But seeing as though you question this, this makes me wonder if your problem isn't in that area?

But either way, we'd need to see some code snippets, to get a better idea what is going on. I suggest "NotePad++" as a off-hand code editor, that way you can copy/paste(and clean) and paste here without showing your nightmare of spaghettis(it's what I do).
