Thanks for the idea with the “Minimum Area Rectangle”. If you use this approach however, you have to make sure that you really have atleast 4 players. I hit my head against the wall yesterday for about an hour till I realized that this function can not work with less than 4 points to calculate a rectangle (hence my “can’t invert nil matrix” errors). So I guess it would be best to check if the players.Num() >=4 and calculate the rectangle, and use the other method otherwise.

Cheers

Thanks for trying it out and leaving a reply!

As of 4.10.0 the Minimum Area Rectangle was working error-free in my prototype with 2 player-controlled characters. My multiplayer is currently limited by the number of controllers I have but I did test with a 3rd and 4th static character and the Minimum Area Rectangle functioned normally in both cases.

I was so keen to be able to contribute something that I’ve likely skipped over something in my blueprints that is necessary to get it all working. As I mentioned at the top of my first post I made a few changes to the original to fit my needs; knowing me I’ve forgotten to include one of those.

I’m in the process of reinstalling UE4 and some Autodesk programs after OS issues. Once I’m set up again I’ll compare my blueprints against the originals here and add another reply with updated screenshots.

Thanks again for replying, take care.

EDIT: Can confirm that I skipped some parts of the blueprint.

In my blueprints I find the float distance between my two players and use that to set the camera arm length. This fits in at Step 2 of my previous post:

Step 3 seen above is also cut in half, here is the rest:

I also recorded a short video with debugging on to show that it works with 2 players:
