Trying to implement "moveToPointer"

[Sammdahamm]

Hi Guys,

so Phaser 2 had a method, game.physics.arcade.moveToPointer() which moved a sprite with a given velocity towards the cursor. It seems like this has been replaced in Phaser 3 by a "moveTo()" method in ArcadePhysics, so I'm trying to reimplement it myself.

I create a spriteGroup:

this.projectiles = this.physics.add.group({collideWorldBounds: true}) 

and then later create & attempt to fire a projectile from within a "fireProjectile" method:
 

  this.firePlayerProjectile = function(projectileType){
        let projectile = this.projectiles.getFirstDead(true, this.player.sprite.x-16, this.player.sprite.y-32, projectileType);
        this.scene.physics.moveTo(projectile, {x: this.scene.input.x + this.scene.cameras.main.scrollX, y: this.scene.input.y + this.scene.cameras.main.scrollY}, 750);
}

This does create the projectile sprite in the correct location, but rather than then travelling towards the target location, it just sorta of flashes and disappears after a second.
Can anyone tell what I might be doing wrong? How do I get the projectile to move to a given location (and beyond) at a constant velocity?

Thanks,

Sam

Parameters

Name	Type	Attributes	Default	Description
gameObject	Phaser.GameObjects.GameObject			Any Game Object with an Arcade Physics body.
x	number			The x coordinate to move towards.
y	number			The y coordinate to move towards.
speed	number	<optional>	60	The speed it will move, in pixels per second (default is 60 pixels/sec)
maxTime	number	<optional>	0	Time given in milliseconds (1000 = 1 sec). If set the speed is adjusted so the object will arrive at destination in the given number of ms.

 

So it either moves 750 px/sec or, more likely, bumps right into {NaN, 750}.

 

this.scene.physics.moveTo(projectile, this.scene.input.x + this.scene.cameras.main.scrollX, this.scene.input.y + this.scene.cameras.main.scrollY, null, 750);

Ah you're totally right! I was wondering where the NaN was coming from  
I got thrown off a bit due to the moveToObject() method taking a {x: y:} object as the destination parameter, I didn't notice that moveTo() was a bit different haha

Been scratching my head on this for while, thanks for the help dude

I've just got this working myself but realised it's not what I need.

 

How would you move an object so it tracked your mouse cursor 1 to 1 instead of moving towards it.

 

I tried setting the objects position to the mouse position using this.object.body.x & .y which worked for moving it about on screen but it then ignored all physics collisions in its path.

@adammarcwilliams did you ever figure it out?
