Hi I am a student currently trying to code an FPS game and the gun isn’t shooting any bullets. It was working at first, and then I added a collision for the bullets to destroy the enemies, and created new scenes and added a switch scene code. Now the gun isn’t working
when I start up the game it only says “403” as an error
then when I make the fps character collide with the Dad (the character with the blue shit) which is supposed to lead the Mission Complete or “End Scene”
and go through all the scene changes and make it back to the main scene, an error pops up later on when I try to left click to shoot saying this
Here is the entire code for our FPS movement which should include charactermovement, camera things and also the gun
var FirstPersonMovement = pc.createScript('firstPersonMovement');
FirstPersonMovement.attributes.add('camera', {type: 'entity'});
FirstPersonMovement.attributes.add('power', {type: 'number', default: 2500 });
FirstPersonMovement.attributes.add('lookSpeed', {type: 'number',default: 0.25});
// ------ gflopez section -----------------------------------------------------
FirstPersonMovement.attributes.add('gunEntity', {type: 'entity'});
FirstPersonMovement.attributes.add('bulletPower', {type: 'number'});
// ----------------------------------------------------------------------------
// initialize code called once per entity
FirstPersonMovement.prototype.initialize = function() {
this.force = new pc.Vec3();
this.eulers = new pc.Vec3();
var app = this.app;
// Listen for mouse move events
app.mouse.on("mousemove", this._onMouseMove, this);
// when the mouse is clicked hide the cursor
app.mouse.on("mousedown", function () {
app.mouse.enablePointerLock();
// ------ gflopez section --------------------------------------------------
this.gflopez();
// -------------------------------------------------------------------------
}, this);
// Check for required components
if (!this.entity.collision) {
console.error("First Person Movement script needs to have a 'collision' component");
}
if (!this.entity.rigidbody || this.entity.rigidbody.type !== pc.BODYTYPE_DYNAMIC) {
console.error("First Person Movement script needs to have a DYNAMIC 'rigidbody' component");
}
};
// update code called every frame
FirstPersonMovement.prototype.update = function(dt) {
// If a camera isn't assigned from the Editor, create one
if (!this.camera) {
this._createCamera();
}
var force = this.force;
var app = this.app;
// Get camera directions to determine movement directions
var forward = this.camera.forward;
var right = this.camera.right;
// movement
var x = 0;
var z = 0;
// Use W-A-S-D keys to move player
// Check for key presses
if (app.keyboard.isPressed(pc.KEY_A) || app.keyboard.isPressed(pc.KEY_Q)) {
x -= right.x;
z -= right.z;
}
if (app.keyboard.isPressed(pc.KEY_D)) {
x += right.x;
z += right.z;
}
if (app.keyboard.isPressed(pc.KEY_W)) {
x += forward.x;
z += forward.z;
}
if (app.keyboard.isPressed(pc.KEY_S)) {
x -= forward.x;
z -= forward.z;
}
// use direction from keypresses to apply a force to the character
if (x !== 0 || z !== 0) {
force.set(x, 0, z).normalize().scale(this.power);
this.entity.rigidbody.applyForce(force);
}
// update camera angle from mouse events
this.camera.setLocalEulerAngles(this.eulers.y, this.eulers.x, 0);
};
FirstPersonMovement.prototype._onMouseMove = function (e) {
// If pointer is disabled
// If the left mouse button is down update the camera from mouse movement
if (pc.Mouse.isPointerLocked() || e.buttons[0]) {
this.eulers.x -= this.lookSpeed * e.dx;
this.eulers.y -= this.lookSpeed * e.dy;
}
};
FirstPersonMovement.prototype._createCamera = function () {
// If user hasn't assigned a camera, create a new one
this.camera = new pc.Entity();
this.camera.setName("First Person Camera");
this.camera.addComponent("camera");
this.entity.addChild(this.camera);
this.camera.translateLocal(0, 0.5, 0);
};
// user-defined function - gflopez section -----------------------------------
FirstPersonMovement.prototype.gflopez = function(dt){
if(GameManager.instance.defaultAmmo <= 0){
return;
}
// step-1 get the center of the screen
var centerScreenX = this.app.graphicsDevice.width/2;
var centerScreenY = this.app.graphicsDevice.height/2;
// step-2 get the start and end point
var start = this.camera.camera.screenToWorld(centerScreenX, centerScreenY, this.camera.camera.nearClip);
var end = this.camera.camera.screenToWorld(centerScreenX, centerScreenY, this.camera.camera.farClip);
// step-3 trigger raycast between two points and return the closest hit result
var result = this.app.systems.rigidbody.raycastFirst(start, end);
if(result){
switch (result.entity.name){
case "enemyBox1":
if((GameManager.instance.defaultHealth1 -=1) ==0){
result.entity.destroy();
};
break;
case "enemyBox2":
if((GameManager.instance.defaultHealth2 -=1) ==0){
result.entity.destroy();
};
break;
case "enemyBox3":
if((GameManager.instance.defaultHealth3 -=1) ==0){
result.entity.destroy();
};
break;
};
GameManager.instance.defaultAmmo -=1;
};
// step-4 set the bullet asset, identify the gunEntity, apply force and create instance
// step-4.1 bullet asset
var bulletAsset = this.app.assets.get(173459041);
// step-4.2 create the instance of the bullet
var bulletInstance = bulletAsset.resource.instantiate();
// step-4.3 add to hierarchy
this.app.root.addChild(bulletInstance);
// step-4.4 identify the gun and set the force
var gun = this.gunEntity;
this.force = new pc.Vec3();
this.force.copy(gun.forward);
this.force.scale(this.bulletPower);
var pos = gun.getPosition();
bulletInstance.setPosition(pos);
bulletInstance.enabled = true;
bulletInstance.rigidbody.applyImpulse(this.force);
};
I am not sure what’s the problem, if the scene changes are causing anything or if there’s something Im not noticing. I would greatly appreciate the help
Here is the link for our playcanvas game
