@rep046 v5.0 introduces bodyguards can pilot various helicopters and shoot enemies for you. I made it semi-open, so you can modify it if you have addon helicopters.

@Nozomu-san Thx for reply, I will try it

@rep046 My pleasure.

Tried with you mod for a bit, the bodyguard works fine, tho i was confused with some of the features:
1 how did you actually change the bodyguard's model? I did not find any thing that looks related to the model in json file.
2 How did you let the bodyguard drive his own vehicle with you?
3It seem's the half and quate-mode make the bodyguard as enemies to my other friendlies, my other friendly would fight my bodyguard even tho they are friendly to me
4 how to change the HP and armor of the guard, they seem too weak in combat.

@rep046 1. There're PlayerProfile/Player(Number).json files. For example, Player1.json.
You change model name mp_m_freemode_01 to someone else. Example: Michael De Santa from Safehouse in the Hills is p_michael_02. Same to other json files. Examples are p_franklin_02, ig_lamardavis_02, player_zero (Yes, is original character, 1 of them is Michael De Santa).
2. First, for example, have both Franklin and MP Protagonist in independent vehicle while relationship is off. Second, assign as bodyguard. Doing so bodyguard will follow you.
3. You must switch to those specific character in order to recognise each other as non-target.
For example, scenario like this: Your original character: Franklin (player_one) and all other bodyguards (1 to 7) are mp_m_freemode_01. All other characters flying surround Franklin. Switch to mp_m_freemode_01, assign to all other mp_m_freemode_01 as allyquarter, if target is 0, you are assigning the original character, which you will set to allyhalf instead. And while as Franklin, assign all mp_m_freemode_01 as allyhalf as you have done.
You must switch to each slot and then assign, since the mod is no longer sync, because syncing will cause bodyguards never come back to you.
If you do all this fine, they will no longer do friendly fire. However they will still leave vehicle if enemies destroyed their helicopters.
Sorry for this complicated but this is done as relation graph, no longer synced on each other. Who is friend, who is not, who is temporarily enemy and so on.
4. That I did not add. Sorry. But what you are talking about is collision proof, which they will not get ragdoll. And high HP you can temporarily use Menyoo Trainer to set character Invincible.
Will look into it when I can figure out like Juggernaut/Ballistic Equipment & Paleto Score's Military Suit on the line with this mod.

@Nozomu-san I maybe dumb, when you said assign as bodyguard means change the relationship to On again right?

@rep046 There are 3 bodyguard modes
1 is crew, aka bodyguard on. Normally you see they follow you on all conditions, if they on helicopter, they will leave vehicle.
2. is halfmode, is to make sure they can fight enemies for you while flying around you. Do not assign to other mp_m_freemode_01 because doing so means protecting too many targets.
3. is quartermode is to make sure issue protecting too many targets not happen, while still can't friendly fire.

@Nozomu-san Play around with you mod more today, now I have more understanding, but still something I was confused.
1. everytime boot game it seem the bodyguard are in random vehicles and random places, is there a way to save their locations and vehicle they in last time, or totally on foot?
2.They can not save their weapon loadout or i missed something?
3. Other than teleport them with U + num, is there a way to let them quit fight and entering my vehicles?
4. is there a way to let bodyguard fight NPCs directly instead only fight back when someone fight us?

@rep046 1. There are choice you can disable spawning on vehicles. If all vehicle entrances is disabled, they will spawn on foot. And, I did randomly base on closest location, if you switch back second time, their location will be saved.
2. I didn't add. Sorry. But doing so means I have to do also with original characters too. For now stick with trainers.
3. Assign as bodyguards and you on vehicle, they will get in.
4. That I didn't add. Sorry, but you can still do it yourself by switching to characters, punch, then switch back to others. They will punch character you just used.

@Nozomu-san is that the json files in StartUpVehicles folder I need to edit to disable the spanwing with vehicles? Like change all the"Enabled": 1 in them to "Enabled": 0?

@rep046 Yes.

So 7.0 do not support legacy? I can not get it work.

@rep046 It uses Script Hook V .NET Enhanced. It supports Legacy too.

@Nozomu-san Can we have Script Hook V .NET Enhanced installed with Script Hook V .NET Nightly? Because I have other scripts need Nightly.

@rep046 I made it for someone who wanna try early. Normally working on overhaul takes time. So have you tested it? Temporarily?

@Nozomu-san I do not have Enhanced version of the game installed on my PC rn, so I do not got a chance to test it. Did that mean the overhaul would come to support Script Hook V .NET Nightly version?

@rep046 Install Script Hook V .NET Enhanced to GTA V Legacy. I tested and it works fine.

@Nozomu-san There is a issue that SHVD Enhanced would replace the dll of SHVD Nightly, cuz some issue with my other script still need the Nightly version, would you update an Nightly version too, so that it works with other scripts.
As for the 7.0 version I tested, and the only thing i dont like is the new AI behavour when combat, I mean the bodyguard do not follow you everywhere like before, they fight their own fight, ran to their cover for too long so not very helpful in fight as before. Ad the press I to call them regroup not always work in combat soemtime they stuck. I feel more like the old combat behavour which bodyguard follows and protect you no matter how.

@rep046 I+int to force them to come back your location. I told you it's not finished. And took a long way to have it done.
