Did you enjoy this video? *Let me know* so I can continue to make awesome content for you :)

[@VMEcycle6]

Great tutorial.👍👍 Well I was working on something very similar six month ago. And I started with a similar approach. But then I realize that when some soldiers got killed in combat. Having other soldiers fill in the gap may trigger all the soldiers to swap their locations, thus will mess up your formation during combat. So I studied flocking algorithm. I let all the soldiers repelling each other, also having the formation "box" attracts all the soldiers. Then calculate a combined vector for each soldier which will determine where a soldier should move. It's kinda hard to have a perfect formation with this method, but it also came with some realism... sort of. Also if a soldier got killed, all you need is just shrink the formation box size to make a tighter formation.

[@Tarodev]

@@VMEcycle6 you could also just cheat. When a unit dies, the positions are recalculated and the remaining units find the closest new position to them and walk to it.

[@xanaramus]

Looks like phyllotaxis, that could be usefull too

[@Tarodev]

@@xanaramus I had to google that. You're right, it does! You can find nature in everything :)

It's amazing. Add such a mini-thing to your game lobby and no one will be bored waiting for challengers.

you cant imagine how helpfull you are! thanks friend!

Wow, good job, so much in the way of settings. I don't need something like that right now, but it was interesting to see how you implemented it. Thanks for that!

[@Tarodev]

😊

[@makoto4541]

Looking for radial instantiation and your video was quite low on the recommended list, but as soon as I saw it was from you, I ignored all other videos and went straight to this one. Your content is reliable, the code is generic, the possibilities are extensive and the explanation is concrete. I find myself often checking first if you have covered the topic before looking elsewhere. Thank you

[@Tarodev]

High praise 🙏 thanks for being a supporter

[@honokiii]

I am looking for a crowd formation method for my current project and saw this. It is not what I am looking for but it is so interesting! Thank you for the idea!

[@youcancallmedoggie]

this is awesome! Please keep doing what you doing. Your content is simply amazing.

[@cyqry]

Looks good as far as function goes and the presentation really nice too. I'm working on a squad-based game and I got to say procedural formations are damned hard so kudos for this. Only thing that comes to mind for improvements is cleaning up how the formation reforms when characters are added or removed. I could never figure out how to improve it and it always felt weird seeing characters sprint from one end of the line to the other instead of just bolting onto the closest end.

[@Tarodev]

So true. Ideally it should detect if any units are close to a new position and re index them to save long walks. Or at the very least give the unit a speed boost when reforming...

[@cyqry]

@@Tarodev For sure. Reindexing sounds like the way to go in this case, I will give that a go on my project when I get some spare time and see how well it works.

[@TheDarkranium]

You can try the Hungarian Algorithm to assign positions so they don't cross over each other's path.

[@cyqry]

@@TheDarkranium I'll look into it, thanks.

[@lonebeaver9535]

Woah I just came here from your reddit post. I just got done implementing box formations in my game and your algorithm is so much more elegant than mine and I was wondering how to achieve radial formations thank you very much!

Great vid, I'm wondering if you could add a flocking componet and would that be ideal to stop clipping between models?

[@YuriNoirProductions]

Do you have any video where you explain how you actually made the individual units wobbly? i only know the concept of having a animated unit and a physical unit that tries to mimic the first one but i have little to know idea how to execute it

[@hyperv4758]

great video how you are avoiding collision between them? or this is not there?

[@_dr_crusher]

Or alternatively, maybe a little insight as to the best way to move around the whole group the same way that you went about it. Super appreciated! Thank you

[@shenshaw5345]

did you ever figure this out?

so great (heart)!

[@LeviAckerman-xt7dx]

This actually looks fun. Can I use this for my commercial mobile game?

[@Tarodev]

Yup, use any code I release :) Let me know if you make anything cool!

[@vaibhavjaiswal799]

Can you give a step by step tutorial of this

[@germiyanbey1]

How to rotate the Formation, any ideas? When I rotate transformY of ExampleArmy (or UnitParent), the formation is overridden to stay same.

[@germiyanbey1]

Okay, I found out, change each transform.position to transform.localPosition in Line 44 (that starts with "_spawnedUnits[i].transform.position") in ExampleArmy.cs. The formation will rotate properly by rotating Y of Example Army gameObj.

Hello!! Thanks for video ,really useful . How should we write a code to add 1 object to the army?

Do you mean add more units? The code I provided should do that for you right out of the box :)

[@Tarodev]

Thanks pal :)

[@tubephega]

go lil chibby go!

[@whidzee]

How hard would it be to take this and make it into a basic sporting game? I'm thinking something like rugby where the defensive team always retreats back 10m and stands in a line and then moves forwards roughly together

[@awsbasim8240]

How do you make the whole formation move How do u add pathfinding to it

[@fortnitegiftcard8541]

I’m trying to make a flying game, how could I change the height of the ai plane in formation to make it look realistic and not a massive straight line

[@bio17]

I like your concise implemetation. Can I ask you why it's better to return an IEnumerable instead of a List in the script BoxFormation?

[@Tarodev]

It simply gives you more performance options. For example you may only want to grab 3 positions, or just loop the first 5. Keeping it an ienumerable means you can simply grab 5 and stop the loop without it grabbing every position. I have a video coming out about ienumerable if that is a little bit confusing.

[@bio17]

@@Tarodev thanks. I'm eagerly waiting for your video about this!

[@TREXYT]

hi, there is an annoying bug where when there is around 17 players or more and you set up _rings to 2 in the inspector then _amount value change every +2, why that ? radial formation is not centred, please fix bro, thanks!

[@lemuelapperson853]

They're not wear pants? JK This is very cool. Part of the radial patterns you were seeing is a known math phenomenon. It gives rise to such things as Moiré patterns.

The only problem is this just scales with rows and columns, not individual units added/removed.

There are more problems than that, I can assure you. This is just a nice little starting point 😊
