javascript - Three.js runs slow if I load a server file
Get the solution ↓↓↓I have a three.js game, I want to be able to load information about different players in the game by loading the file with either php or ajax. But if I load a file at all, the three.js game gets very slow and choppy.
Here is my code:
<?php
$file1 = fopen("Profiles/person1.player", "r");
$file2 = fopen("Profiles/person2.player", "r");
$text1 = fread($file1, filesize("Profiles/person1.player"));
$text2 = fread($file2, filesize("Profiles/person2.player"));
?>
