Players have no weapons for other players

Yazir · March 15, 2017

Hello!

I have a problem that i couldn't solve for the past month. I am making a gamemode. On start of the round i spawn players in different dimension in air, with parachutes (given by giveWeapon). They can pick up weapons and walk around the map, but sometimes player don't see other player's (player2) weapon and even if the player2 is shooting at him, he doesn't deal any damage.

What could be the issue? Please help me. I have tried many various things like manually giving weapon to a player, setting his weapon and sending a message to players to update player2 but with no result. Tried moving/spawning into other dimension in one place then moving them in air. Or the same but spawning far away (thought it could be some streaming issue). No results.

Setting giveWeapon's set as current to false seemed like it kinda made the issue happen less often.

Weapons that are given when the player is nearby are visible.

How often does the bug happen?

Can you supply an example resource which shows the problem?

Yazir · March 15, 2017

It seems random, sometimes it is every match, sometimes it's not happening.

The gamemode and resource is written by myself, but i can provide you scripts where i spawn player etc.

for key,player in ipairs(lobby["players"]) do
	local skin = getElementData( player, "skin" )
	addStat(player,"played",1)
	spawnPlayer( player, -1500*key,-1500*key,1500*key, nil, skin, nil, dim)
	setElementDimension( player, dim )
	setElementPosition( player, 1000*key, 1000*key, 1000*key )
	setTimer(
	function()
		setElementData( player, "canFire", true )
		giveWeapon( player, 46, 1, true)
		setElementDimension( player, dim )
		setElementPosition( player, math.random(-700,700)+x, math.random(-500,500)+y, 800, true )
		setElementVelocity( player, math.random(-30,30), math.random(-30,30), 50 )
		setElementData( player, "headshotMulti", 2 )
		setElementData( player, "score", -1 )
	end,2000,1)
end

Player spawning. Tried delaying changing dimension/spawning and spawning players far apart.

if itemdata[3] == "equip" then
	giveWeapon( source, itemdata[4], itemdata[5], true)
	removePlayerItem(source, iid, item)
end

Code for giving weapon when player equips them. Players can equip item any time they want (single time). Setting set current weapon to false seemed to help, made it happen less often but that might have been just random.

It was a problem for this gamemode for since i remember. Also when player shoots and you don't see his weapon, he occasionally swings his fist and when he's moving it looks like he is running in a direction and gets warped back to the position he was standing originally every position update.

also that happens in other servers so that player (player 2)who can't deal damage to (player 1)have to killed so it get fixed but yeah it have to be fully fixed

Yazir · March 20, 2017

The problem is still there. It makes my server nearly unplayable.

Yazir · March 21, 2017

I have found this post with I think similar issue:

Though there's no solution as the author just closes the topic.

On the other hand I wanted to make something like this

addEventHandler( "onPlayerWeaponFire", root,
function ( wep, eX, eY, eZ, hitE, sX, sY, sZ )
	local amm = getPedTotalAmmo( source )
	local clip = getPedAmmoInClip( source )
	outputChatBox( tostring( amm ) )
	takeWeapon( source, wep, amm )
	giveWeapon( source, wep, amm-1, true )
end )

But as i have made this, I've seen that there is no function to get and set player's ammo in clip serverside.

ccw · March 21, 2017

Try this and see what gets output in the server log:

Client:

function sendinfo()
    local slotinfo = {}
    for i,player in ipairs(getElementsByType("player")) do
        slotinfo[player] = getPedWeaponSlot(player)
    end
    triggerServerEvent("onSlotInfo", resourceRoot, slotinfo)
end
setTimer(sendinfo,1000,0)

Server:

addEvent( "onSlotInfo", true )
addEventHandler( "onSlotInfo", resourceRoot,
    function ( slotinfo )
        for _,player in ipairs(getElementsByType("player")) do
            local slotServer = getPedWeaponSlot(player)
            local slotClient = slotinfo[player]
            if slotServer ~= slotClient then
                setPedWeaponSlot( player, 0 )
                setPedWeaponSlot( player, slotServer )
                outputDebugString( "onSlotInfo"
                            .. " client:" .. tostring(getPlayerName(client))
                            .. " player:" .. tostring(getPlayerName(player))
                            .. " slotServer:" .. tostring(slotServer)
                            .. " slotClient:" .. tostring(slotClient)
                                )
            end
        end
    end
)

Though weapons were visible that round

Rat32 · March 22, 2017

I saw this bug too. In my screen player2 shooted me with fists when he had M4.

Yazir · March 22, 2017

Here is log of when the issue happened (from match start till the end)

At what point did the issue occur, and which players were involved?

Yazir · March 23, 2017

I have made another test because previous wasn't made by me. They've told me they both didn't see their weapons

There's a new test with the bug after a few tries (with your code)

http://cdn.pasteraw.com/c5zr12qtyge4ssv0hfk1n2y2yaphgi0

The issues were: Pogromca_ didn't have a weapon for me ( i didn't see his shotgun) and when he tried to shoot, it wouldn't let him (after pressing lpm nothing happened).

Next round I've got the issue myself and it happened with mac-10 in middle of shooting. I couldn't shoot anymore resulting in my death.

Pogromca_ now has weird issue that if he starts running while he is aiming, the weapon will get changed. Didn't experience that myself and maybe it's affected cause of your script.

@ccw

edit: I couldn't shoot because i had 0 ammo. I have also made custom weapons with setWeaponProperty. Maybe that might help.

Yazir · March 25, 2017

No solution so far.

ccw · March 25, 2017

Make a client script which displays all the weapons and ammo of the remote players.
e.g.

for i,plr in ipairs(getElementsByType("player")) do
    for slot=0,12 do
        weap = getPedWeapon(plr,slot)
        ammo = getPedAmmoInClip(plr,slot)
        dxDrawText( plrname .. weap ..ammo ..

Yazir · March 26, 2017

It was hard to work with them but I've got some screenshots

function renderDebug(  )
	for i,plr in ipairs(getElementsByType("player")) do
		if not isElement( plr ) then return end
	    for slot=0,12 do
	        weap = getPedWeapon(plr,slot)
	        ammo = getPedAmmoInClip(plr,slot)
	        ammoTot = getPedTotalAmmo( plr, slot )
	        dxDrawText( slot .. " " .. getPlayerName( plr ) .. " (D".. getElementDimension( plr ) .. ") " .. tostring(weap) .. " " .. tostring(ammo) .. "/" .. tostring(ammoTot), 230 + i * 180, slot*15, tocolor( 255, 255, 255, 150 ), 0.5 )
	    end
	end
end

local isWpnDebug = false
addCommandHandler( "wpndebug", 
function ( )
	if not isWpnDebug then addEventHandler( "onClientRender", root, renderDebug ) isWpnDebug = true outputChatBox( "ON" )
	else removeEventHandler( "onClientRender", root, renderDebug ) isWpnDebug = false end
end )

Code of that display

And I'm really sorry because I've just seen this topic is in Windows, not Linux thread. The server is on linux.

From my observations it seems that players that are not streamed in and player equips them and sets as their weapon, are invisible later ( I've used giveWeapon setWeaponCurrent=true to make the bug happen more frequently).

There was one little bug that one guy seen I have shotgun, but in reality i had chainsaw. I "shot" it once and it got fixed. It was one of the first screens. On the last screens me (harley quinn model) have no weapon in demonek's ss.

Please try with this client:

https://nightly.multitheftauto.com/?mtasa-1.5-rc-latest

Yazir · March 28, 2017

Tested on 2 clients and it doesn't work.

Note: Weapons given when player is nearby other player are visible (except when the weapon is already invisible, but I'm not sure about this one).

Edited March 28, 2017 by Yazir

ccw · March 28, 2017

client side getPedWeapon(plr,slot) should now work even if the player is far away So use your renderDebug script to see what happens when a streamed out player equips himself

Yazir · March 30, 2017

Weapons are set to 0 (when bug occurs).

It works normally without the bug (weapons are given).

Edited March 30, 2017 by Yazir

ccw · March 31, 2017

Please test with this client:

https://nightly.multitheftauto.com/?mtasa-1.5-rc-latest

Yazir · March 31, 2017

It seems to be working. After 4 games with 2 players (new client(me) + old client) I have seen every weapon and the old one didn't see my weapons atleast twice.

Then 3 games both with new clients it worked perfectly till one moment. Other player didn't see most of my weapons (he saw only one, tec-9) but when i threw satchel at him, all my weapons were visible after that.

I suggest pushing this update already because it works nearly perfectly.

Thanks.

Yazir · April 1, 2017

After full day of testing I can tell, I didn't come around the bug in my client (everyone could shoot me) but sometimes I couldn't hit others because they had the old client.

ccw · April 2, 2017

That's good news.

Please test the latest as I've made another tweak and I want to make sure it still works for you:

https://nightly.multitheftauto.com/?mtasa-1.5-rc-latest

Yazir · April 8, 2017

Sorry, I didn't check the forums for couple days. I thought the update has been pushed and it works fine on my server now as I or my players experience the issue. There was only one occurence but that was when player still had outdated client.

I will test it soon.

There's however another issue not related to this problem:

Yazir · April 9, 2017

Didn't find any issues with that client.

Players have no weapons for other players
