Example 11：No Path line has been shown

[Simon1059770342]

Hi Nik! When I accessed index.html from the example 11 on my phone with Chrome, No Path line has been shown even I called showPathLines() without debugging as follow:
`newPath(pt){
const player = this.object;

    if (this.pathfinder===undefined){
        this.calculatedPath = [ pt.clone() ];
        //Calculate target direction
        this.setTargetDirection();
        this.action = 'walk';
        return;
    }
    
	//console.log(`New path to ${pt.x.toFixed(1)}, ${pt.y.toFixed(2)}, ${pt.z.toFixed(2)}`);	

	const targetGroup = this.pathfinder.getGroup(this.ZONE, pt);
	const closestTargetNode = this.pathfinder.getClosestNode(pt, this.ZONE, targetGroup);
	
	// Calculate a path to the target and store it
	this.calculatedPath = this.pathfinder.findPath(player.position, pt, this.ZONE, this.navMeshGroup);

	const self = this;
	
	if (this.calculatedPath && this.calculatedPath.length) {
		this.action = 'walk';
		
		const pt = this.calculatedPath[0].clone();
		this.setTargetDirection()
		
		if (!this.npc){
			this.showPathLines();
		}
	} else {
		this.action = 'idle';
		`
		THX for your HELP!
