Why does the script only work with pictures from the system files, but not with pictures from a link from the Internet?
Hello, why is it that when I specify the local image path (eg images/player.png ) the script works, but when I specify a link from the Internet (eg https://skin.vimeworld.ru/raw/skin/player.png ) it doesn't.
How to fix it?
The script itself (when you call it with skinURL = https://skin.vimeworld.ru/raw/skin/player.png does not work):
var THREEx = THREEx || {};
/**
* [ description]
* @param {[type]} skinUrl [description]
* @return {[type]} [description]
*/
THREEx.MinecraftChar = function(skinUrl){
// set default arguments values
skinUrl = skinUrl || (THREEx.MinecraftChar.baseUrl + "images/player.png");
var texture = new THREE.Texture
texture.magFilter = THREE.NearestFilter;
texture.minFilter = THREE.NearestFilter;
this.texture = texture
this.loadSkin( skinUrl );
var defaultMaterial = THREEx.MinecraftChar.defaultMaterial || THREE.MeshBasicMaterial
var material = new defaultMaterial({
map : texture
});
var materialTran= new defaultMaterial({
map : texture,
transparent : true,
depthWrite : false,
side : THREE.DoubleSide
})
