NetworkAllowLocalEntityAttachment not working as expected

[draobrehtom]

What happened?

When using NetworkAllowLocalEntityAttachment, it doesn't work. This problem was previously described in this issue. Feel free to close this issue and re-open the old one if needed.

One major difference from the previous issue: the bug did not occur in build 2372. However, it now happens in both build 2372 and 2545, as well as in newer builds.

Current Behavior:

2022-06-14_13-03-54.mp4

Expected Behavior:

2022-06-14_13-18-57.mp4

Code to Reproduce:

local delete = {}

RegisterCommand('attachself', function()
    RequestModel(`v_corp_bk_chair2`)
    local coords = vector3(810.84, -3035.94, 5.74)
    local chair = CreateObject(`v_corp_bk_chair2`, coords.x, coords.y, coords.z, false, false, false)
    table.insert(delete, chair)

    NetworkAllowLocalEntityAttachment(PlayerPedId(), true)
    AttachEntityToEntity(
        PlayerPedId(), chair, 0, 1.0, 0.0, 0.0, 0.0, 0.0, 0.0, false, false, false, false, 0, true
    )

    while true do
        Wait(0)
        
        i = GetNetworkTimeAccurate() / 10

        local offsetPos = vector3(math.cos(math.rad(i)), math.sin(math.rad(i)), 0.0) * 4
        SetEntityCoords(
            chair, 
            coords + offsetPos + vector3(0.0, 0.0, 0.0 + math.sin(i/50) / 2),
            false, false, false, false
        )
    end
end, false)

AddEventHandler('onResourceStop', function(name)
    if GetCurrentResourceName() == name then
        for _, b in pairs(delete) do
            DeleteEntity(b)
        end
    end
end)

Expected result

Native should attach player without lags

Reproduction steps

1. Use the attached code in the description.
2. Connect to the server with two players (both can be on the same PC using -cl2).
3. Place both players at the testing location. You can use the following code to teleport:

SetEntityCoords(PlayerPedId(), 810.84, -3035.94, 5.74)

4. On Player 1 (P1), execute the command /attachself.
5. On Player 2 (P2), observe the behavior.

Specific version(s)

Tested on game builds 2372 and 3258 - same issue on both. Tested on server artifacts 13079.

A workaround is available using NetworkSetEntityCanBlend, though the synchronization could be smoother:

RegisterCommand('fixattach', function(source, args)
    local serverId = tonumber(args[1])
    if not serverId then
        print("ERROR: Usage /fixattach <serverid of player who ran /attachself>")
        return
    end

    local ped = GetPlayerPed(GetPlayerFromServerId(serverId))
    NetworkSetEntityCanBlend(ped, false)
end)
