I have trouble with Phaser.js. It's a copy of example from phaser.io/examples. And what the hell with it?
var game = new Phaser.Game(400, 200, Phaser.AUTO, 'phaser-example', {
preload: preload,
create: create,
update: update,
render: render
});
function preload() {
game.load.image('arrow', 'img.png');
}
var sprite;
function create() {
sprite = game.add.sprite(50, 50, 'arrow');
}
function update() {}
function render() {}

The problem is that you have set up a Phaser 2 game, while in your html you call the Phaser 3 library.
In Phaser 3 you can start a game like this:
var config = {
type: Phaser.AUTO,
width: 800,
height: 600,
scene: {
preload: preload,
create: create,
update: update,
render: render
}
};
var game = new Phaser.Game(config);
function preload() {
this.load.image('arrow', 'img.png');
}
var sprite;
function create() {
sprite = this.add.image(50,50, 'arrow').setOrigin(0,0);
}
function update() {}
function render(){}

i would like to create a battle system for an rpg game ,where an opening animation plays showing the battling characters move from the side of the screen to a location on the screen. Current code, assets and current running view provided below;
<!doctype html>

<title>battle</title>

}
},
scene: {

var game = new Phaser.Game(config);

bot.setScale(5);
};
function update(){

</script>
</body>
water_hydrant/hydrobot
the battle background
the current view when running the code
much appreciated thanks :)
Yes, check for tween. You can move the image by using it.
So I have this code that will run a game being this the base of that game. it uses phaser.
I was trying to run it on xampp on htdocs/itw/test.html
with the 2 pngs and json file being located on htdocs/itw/assets/
the pngs are tilesets and the json tilemap
but I get this errors on console executing the indext.html
Any Help would be awsome

.. represents parent directory. Try removing them in your load statements
Ex.
../assets/outside.png to assets/outside.png
I've been attempting to learn Phaser 3 so I can support my students in learning the framework. I've been able to get a spritesheet working, however, I'd prefer to use a json file, so I'm using the load atlas instead. The problem I'm having no matter what I try is that the update method is giving an error when I attempt to play the animation I created in the create method.
It says, Uncaught TypeError: Cannot read property 'frame' of undefined
I'm exporting my json and spritesheet using LeshyLabs https://www.leshylabs.com/apps/sstool/
Here's my code. Any help would be very much appreciated.

In your load statement, you're naming the atlas 'megaman' (name will be the first parameter passed into the load method). Then, in the anims.create() method, you're referencing an atlas called 'stand' to generate the frame names. That's why you're getting undefined.
You can see an example of setting up animations with an atlas here: Phaser Labs - Animation from Atlas.
In the meantime, if you change your create method to this, it should work:
this.anims.create({
key:'standing',
frames: this.anims.generateFrameNames('megaman', {
prefix:'stand',
end:7,
zeroPad: 2
}),
repeat: -1
});
So I was in the middle of game development with Phaser 3 and this error showed up in the console:
Cannot read property 'startSystem' of undefined

I'm running on a local host.

Any help will be welcomed!
There are some errors I found in your example, maybe these steps will help to fix it:
You don't need to call game.physics.startSystem(Phaser.Physics.ARCADE); at all. Just remove this line.
Add update function
platforms.create will fail since platforms are not initialized. Here is example about groups
game.add will also fail - you don't need game, use this to access current scene.
There are a lot of examples with Phaser 2 that uses game, but in Phaser 3 you can just access the scene from create and update to add new objects.
Im trying to add a simple menu to my Phaser game that loads first, then once someone clicks on a button the game actually starts. I can figure out how to add the buttons later, I just cannot figure out how to add the menu screen. Ive researched quite a few ways online on how to get this done but none have worked for me. I've also tried breaking the code up into different states but that didnt work for me either. Maybe I was doing it incorrectly. Can someone show me correct way to add a menu to my game that loads before the actual game does?
