Hi there,
I am looking into how projectiles can be fired, my intention is to try and fire in the direction that the cursor is at ( me.input.pointer.pos ).
My first idea was to try and work out if the cursor needs to move in a positive or negative direction, I added `mainPlayer` to the pool, so somehow if I can get the position of them then I can work out which way to shoot in regards to right or left, but I'm not sure how to access the `mainPlayer`.
How would you go about solving this problem? My Entities are below so you can see how they currently react
/**
* Player Entity
*/
game.PlayerEntity = me.Entity.extend({
/**
* constructor
*/
init: function (x, y, settings) {
settings = settings || {
image: 'character_default_run',
height: 32,
width: 32
};
// call the constructor
this._super(me.Entity, 'init', [x, y, settings]);
// set the default horizontal & vertical speed (accel vector)
this.body.setVelocity(1, 1);
// set the display to follow our position on both axis
me.game.viewport.follow(this.pos, me.game.viewport.AXIS.BOTH);
// ensure the player is updated even when outside of the viewport
this.alwaysUpdate = true;
// define a basic walking animation (using all frames)
this.renderable.addAnimation("walk", [0, 1, 2, 3, 4, 5, 6, 7]);
// define a standing animation (using the first frame)
this.renderable.addAnimation("stand", [0]);
// set the standing animation as default
this.renderable.setCurrentAnimation("stand");
this.body.collisionType = me.collision.types.PLAYER_OBJECT;
},
/**
* update the entity
*/
update: function (dt) {
if (me.input.isKeyPressed("action1")) {
var action = me.pool.pull("iceBeam", this.pos.x, this.pos.y);
me.game.world.addChild(action);
}
if (me.input.isKeyPressed("run")) {
this.body.setVelocity(2, 2);
}
else
this.body.setVelocity(1, 1);
if (me.input.isKeyPressed("left")) {
// update the entity velocity
this.renderable.flipX(true);
this.body.vel.x -= this.body.accel.x * me.timer.tick;
if (!this.renderable.isCurrentAnimation("walk")) {
this.renderable.setCurrentAnimation("walk");
}
} else if (me.input.isKeyPressed("right")) {
// unflip the sprite
this.renderable.flipX(false);
// update the entity velocity
this.body.vel.x += this.body.accel.x * me.timer.tick;
// change to the walking animation
if (!this.renderable.isCurrentAnimation("walk")) {
this.renderable.setCurrentAnimation("walk");
}
}
else {
this.body.vel.x = 0;
}
if (me.input.isKeyPressed("up")) {
// update the entity velocity
this.body.vel.y -= this.body.accel.y * me.timer.tick;
if (!this.renderable.isCurrentAnimation("walk")) {
this.renderable.setCurrentAnimation("walk");
}
} else if (me.input.isKeyPressed("down")) {
// update the entity velocity
this.body.vel.y += this.body.accel.y * me.timer.tick;
if (!this.renderable.isCurrentAnimation("walk")) {
this.renderable.setCurrentAnimation("walk");
}
} else {
this.body.vel.y = 0;
}
if (this.body.vel.y === 0 && this.body.vel.x === 0)
this.renderable.setCurrentAnimation("stand");
this.body.update(dt);
// handle collisions against other shapes
me.collision.check(this);
// return true if we moved or if the renderable was updated
return (this._super(me.Entity, 'update', [dt]) || this.body.vel.x !== 0 || this.body.vel.y !== 0);
},
/**
* colision handler
* (called when colliding with other objects)
*/
onCollision: function (response, other) {
if (other.body.collisionType === me.collision.types.PROJECTILE_OBJECT) {
return false;
}
// Make all other objects solid
return true;
}
});
game.Spell = me.Entity.extend({});
game.Spell.Icebeam = game.Spell.extend({
/**
* constructor
*/
init: function (x, y, settings) {
settings = settings || {
image: 'short-ray',
height: 86,
width: 16
};
// call the constructor
this._super(me.Entity, 'init', [x, y, settings]);
this.alwaysUpdate = false;
this.body.collisionType = me.collision.types.PROJECTILE_OBJECT;
var pos = me.input.pointer.pos;
this.endX = pos.x;
this.endY = pos.y;
console.log('Aiming at', pos);
},
update: function (dt) {
this.body.setVelocity(3,3);
// If the current position isnt at the endpoint then move it there
console.log(me.game.world.getChildByName("mainPlayer"));
// if(this.pos.x <= this.endX && this)
// {
// // Set x velocity
// this.body.vel.x += this.body.accel.x * me.timer.tick;
//
// }
// else
// me.game.world.destroy(this);
// handle collisions against other shapes
me.collision.check(this);
this.body.update(dt);
// return true if we moved or if the renderable was updated
return (this._super(me.Entity, 'update', [dt]) || this.body.vel.x !== 0 || this.body.vel.y !== 0);
},
onCollision: function (response, other) {
if (other.body.collisionType === me.collision.types.PROJECTILE_OBJECT || other.body.collisionType === me.collision.types.PLAYER_OBJECT) {
return false;

Appreciate any pointers, thanks
