When it comes to NPC

How to do when you approach the NPC, the action takes place?
Sorry my bad English D:

 

Are you looking for a way to trigger an action by proximity?

 

In the plugin GoldSTD, when you go to the dealer, he's texting. Climbed the entire code, can't find

 

I think I understand what you're wanting, here is a snippet of code .

PHP:

//$npc MUST be an entity.
//$p MUST be an player
//the code here would be used on PlayerMoveEvent

if($p->getLevel() !== $npc->getLevel())
{
    return; //we dont want to execute useless code that would slow the server down even more
}

$minDistance = 2; //distance a player must be before "entity" starts talking to them

$distance = round($p->distance($npc)); //we are rounding the number because the distance could be a decimal and a player would be spammed
if($distance > $minDistance)
{
    return; //the player is too far away
}

//your code here

 

Yes, thank You very much
