Any ideas?

Good afternoon, I'm trying to check intersection between 2 meshes. For that I created 2 bounding boxes. When the intersection happens, the NPC should pursuit the ship. Although, it's not working, for some reason, the NPC is behaving like it had intersedted all of the meshes in the screen at the same time (like if the bounding box had infinite size. there's part of the code. activate is called on the main scope, The example his checking the intersection between the this.boundingbox and the playermesh, but i already tried with the boundingboxship (of the player), and tried with "false" also, it doesn't work, with false doesn't detect anything at all. I also commented out all the collision stuff, including the ellipsoids, still nothing. Thanks for the help in advance. patroller.prototype.activate = function(){ var a = this.units.length - 1; console.log(this.arrived); if (this.arrived === true){ var tempx = Math.floor(Math.random()*(this.mapSize-1+1)+1); var tempz = Math.floor(Math.random()*(this.mapSize-1+1)+1); this.targetX = tempx; this.targetZ = tempz; this.arrived = false; } //estado patrol if ((this.arrived === false) && (typeof(units[a].getMesh())!=="undefined")&&(typeof(this.mesh)!=="undefined")){ //this.npcPosX = temp.getPositionX(); //this.npcPosZ = temp.getPositionZ(); this.move(this.targetX,this.targetZ); //var meshtemp = units[0]; //console.log(units[0].getMesh()); //console.log(meshtemp.mesh); for (var i=0; i<this.units.length; i++){ if (typeof(this.units[i].getMesh())!=="undefined" ){ //console.log(units[i].getMesh()); //console.log(this.mesh); //console.log(meshtemp); //console.log(this.boundingBox); //console.log(units[i].boundingBoxShip); if (this.boundingBox.intersectsMesh(this.units[i].getMesh()),true){ console.log("funciona"); this.attackedUnit = this.units[i]; //estado de perseguição this.move(this.units[i].getShipPosx(),this.units[i].getShipPosz()); var targetx = units[i].getShipPosx(); var targetz = units[i].getShipPosz(); var posix = this.getPositionX(); var posiz = this.getPositionZ(); var dx = targetx - posix; var dz = targetz - posiz; var vector = Math.sqrt(dx * dx + dz * dz); if (vector<=25){ //estado de ataque //attack (); } } if (this.armor<5){ //estado de fuga this.move(Math.floor(Math.random()*(this.mapSize-1+1)+1),Math.floor(Math.random()*(this.mapSize-1+1)+1)); } } }
