Getting Player Client ID

Posted by Shaddovv

Heey size!

I use the id's of the players and put them into a variable named target to make de AI follow that target. Only when i put gms_self_playerid() in it with the object thats actually hitting the AI it gives an error and when i use the normal id it only makes it follow the client_master (client that first logged in) how can i make it so that when the player attacks the AI actually follows the player instead of only the client master?

Thanks for youre time :)

Note that gms_self_playerid() will not return an id that references a valid instance. You can use something like this:

var stored_player_id;
stored_player_id = target;
with obj_player
{
    if player_id == stored_player_id // player_id is a variable every "other player object" has
    {
        // do something
    }
}

Could you give me a more detailed example of this method? What do you mean with Stored_player_id and what should be the player_id that returns?

stored_player_id should be the player_id of another player. I'm guessing that it's the player_id of the player that's currently targeted by the enemy?

When i try to refer to player_id it says the variable doesnt exists?

The player_id variable only exists in other player objects.

You can use gms_self_playerid() to get the id of the current player.

Oops, seems like I already replied to this below. You can ignore this post.

player_id only exists on other player objects. It seems like you're trying to get the player_id of an instance of the obj_greatsword object. Without knowing what player you're trying to refer to, I can't give more specific advice.

You can use gms_self_playerid() to get your own playerid.

The example above implies that you have a variable named player_id with this value

I dont want to get youre own ID i want to get the instance id's of other player_id's wich i cant seem to figure out. :/

I know, but that's the solution for your error you pasted above :)

Either way the instance ID's are the same on every client, if I recall correctly

GameMaker's instance IDs differ, there's no way for the extension to control that. The syncIDs or playerIDs (used in instance synchronisation and player synchronisation respectively) share the same value across multiple clients.

I dont think they are actually

I'll try to test this in a controlled testproject later today, and tell you the results. Quite curious myself!

For a workaround you can set the id as a custom variable to sync with the instance

Yes but that custom variable needs to be in every gms_master client wich can be everyone, and everyone has another set of variables so that means that they will link to different objects, so that doesnt work.
