[SOLVED] How to switch between two character controllers on keypress

Help & Support
,
#1

Hi, I’m very new to scripting and I’m trying to switch between two characters when x is pressed. The two characters I am switching between are the drill and the stickman. If someone could send a script or fork my game and create a script it would be much appreciated.

@John_Delbaere Hi and welcome to Playcanvas. Here are a few resources we have to get you going. First the key controls can be reference here.

https://developer.playcanvas.com/en/tutorials/keyboard-input/

There are several examples that use keyboard keys in this section of tutorials.

https://developer.playcanvas.com/en/tutorials/

What is nice about the tutorials is that you can fork any one of the examples and make them your own for adding or changing scripts.

Just a follow up question, I wrote this script

var Stickmanmovement = pc.createScript('stickmanmovement');

// initialize code called once per entity
Stickmanmovement.prototype.initialize = function() {
    
};

// update code called every frame
Stickmanmovement.prototype.update = function(dt) {

    this.playerPos = this.entity.getLocalPosition();

    var app = this.app;

 if (this.app.keyboard.isPressed(pc.KEY_LEFT)) {
        this.entity.rigidbody.applyTorque (4,0,0);
    }

 if (this.app.keyboard.isPressed(pc.KEY_RIGHT)) {
        this.entity.rigidbody.applyTorque (1,0,0);
    }
 if (this.app.keyboard.isPressed(pc.KEY_UP)) {
     this.entity.rigidbody.applyForce(0,0,10);
    }

 if (this.app.keyboard.isPressed(pc.KEY_DOWN)) {
     this.entity.rigidbody.applyForce(0,0,10);
    }
  if (app.keyboard.wasPressed(pc.KEY_R) ) {
        this.reset();
    }
};

Stickmanmovement.prototype.reset = function () {

    this.entity.rigidbody.linearVelocity = pc.Vec3.ZERO;
    this.entity.rigidbody.angularVelocity = pc.Vec3.ZERO;
};

but when I press the arrow keys nothing seems to happen. I added it into the stickman and it has all the components needed. If you could tell me what I need to fix it would be much appreciated. By the way here is my project game.

@John_Delbaere I took a look at you project link above and I am sorry but I do not see this code.

Sorry, I think I sent the wrong link. This should work https://playcanvas.com/project/1061106/overview/mining-mania
I’ve made some changes to the code in order to play animations but it seems those are also working incorrectly.

@John_Delbaere Your keys are working. I just put in a few console.log()s to capture the key strokes in the debugger. Also, there were some semi colons missing. Here is the code.

var Stickmanmovement = pc.createScript('stickmanmovement');
Stickmanmovement.attributes.add('modelEntity', {
    type: 'entity'
});
// initialize code called once per entity
Stickmanmovement.prototype.initialize = function() {
    
};

// update code called every frame
Stickmanmovement.prototype.update = function(dt) {

    this.playerPos = this.entity.getLocalPosition();
    var force = this.force;
    var app = this.app;
    // movement
    var forward = this.modelEntity.forward;
    var x = 0;
    var z = 0;
    

 if (this.app.keyboard.isPressed(pc.KEY_LEFT)) {
        console.log('KEY_LEFT_is');
        this.entity.rigidbody.applyTorque (4,0,0);
    }

 if (this.app.keyboard.isPressed(pc.KEY_RIGHT)) {
        console.log('KEY_RIGHT_is');
        this.entity.rigidbody.applyTorque (1,0,0);
    }
    
 if (this.app.keyboard.isPressed(pc.KEY_UP)) {
        console.log('KEY_UP_is');
        x += forward.x;
        z += forward.z;
     this.entity.anim.setTrigger('Walking Forward');
 }
 if(this.app.keyboard.wasReleased(pc.KEY_UP)){
    console.log('KEY_UP_was');
    this.entity.anim.setTrigger('Idle');
}
 if (this.app.keyboard.isPressed(pc.KEY_DOWN)) {
    console.log('KEY_DOWN_is');
    x -= forward.x;
    z -= forward.z;
    this.entity.anim.setTrigger('Walking Backward');
 }
 if(this.app.keyboard.wasReleased(pc.KEY_DOWN)) {
    console.log('KEY_DOWN_was');
    this.entity.anim.setTrigger('Idle');
 }

  if (app.keyboard.wasPressed(pc.KEY_R) ) {
        this.reset();
    }
        if (x !== 0 && z !== 0) {
        force.set(x, 0, z).normalize().scale(this.power);
        this.entity.rigidbody.applyForce(force);
    }
};

Stickmanmovement.prototype.reset = function () {

    this.entity.rigidbody.linearVelocity = pc.Vec3.ZERO;
    this.entity.rigidbody.angularVelocity = pc.Vec3.ZERO;
};

Output in debugger

I am not sure about what you really want to do in your position updates. You should probably have another look and follow it through. Please post a new topic referencing any new issue. We should probably mark this as solved since it does not match the topic of this post.
