Hey guys,

I'm following the https://www.appgamekit.com/documentation/examples/multiplayer/0_getting_started.htm documentation in order to create a simple multi-player game for 2 to max 4 players .
The simple idea that i want to make :
- a player hits with his sprite , another sprite already present on the map (let's say 3 times) , and then from that sprite, 2 more sprites should appear near them, like some items.

The question is how do i sent that concept to multi-player game? Until now, after hitting 3 times the sprite, 2 sprite appears only for the user that hit the sprite, for the other ones did not. <--main problem
Also, i would love to know if its possible after creating them to know their if it's possible to know their id's or something like that to create another function like : keeping pressed on the button on the keyboard or button activation to move the 2 sprites with the player if he touches them (like lift and move the object )

Thanks,
Alex

You want to count the hits in the host session
The host only should judge those things so cheating gets harder

So you check in the Host session if the sprites hit and after the 3rd time you send that event to all other clients

Not sure but maybe you are looking for: SetNetworkClientUserData() and GetNetworkMyClientID()

Pseudo code:

Host:

+ Code Snippet

for ClientID=0 to Client.length
	if GetSpriteHit(ClientID[ClientID].SpriteID)<>0
		SetNetworkClientUserData(Net_NetworkID,NetID,0,GetNetworkClientUserData(Net_NetworkID,NetID,0)+1)
	endif

	if GetNetworkClientUserData(Net_NetworkID,NetID,0)=3
		SetNetworkClientUserData(Net_NetworkID,NetID,0,0)
		MessageID=CreateNetworkMessage()
		AddNetworkMessageInteger(MessageID,NET_EVENTHIT)
		AddNetworkMessageInteger(MessageID,ClientID)
		SendNetworkMessage(Net_NetworkID,0,MessageID)
	endif
next ClientID

Client side:

+ Code Snippet

MessageID=GetNetworkMessage(Net_NetworkID)
while MessageID<>0
	Option=GetNetworkMessageInteger(MessageID)
	select Option
		case NET_HIT:
			ClientID=GetNetworkMessageInteger(MessageID)
                        if ClientID=GetNetworkMyClientID(Net_NetworkID) then print("You hit someone")
			// Do what ever needs to be done here
		endcase
	endselect
	MessageID=GetNetworkMessage(Net_NetworkID)
endwhile
