how to add enemy over a platform ?(tilemap)

[jopcode]

Hi guys, i want to add an enemy over a platform and this enemy can move in the limit of the selected platform, i'm using tilemap created with tiled, but i do not have idea how do it, any idea?

If you want to add an enemy, you need to add a Tileset in Tiled and Place it as Object.

Then you need to save the file as .json and in the play.js you need to compile it in the Game.

 

e. g. : 

map.createFromObjects('obj1', 2, 'floor', 0, true, false, Floor);

'obj1' is the name of the Object in Tiled

'2' is the gid ID in the .json file

'floor' is the TilesetImage you added in the play.js like:

'Floor' is the variable you defined in the index.html

map.addTilesetImage('floor', 'water', 'frog');

Correct me if I'm wrong.

How you do the enemy only move in the limited Platform, I dont know either.

Hope someone can answer.

@ITpaoloBut, my map has been already created, tileset, json etc has been created and placed, i want place a enemy over a platform already created, and this enemy only can moved(right to left, left to right) over this platform.

Is the enemy a tile layer?

If yes, I dont know, I do my enemys with the Object function and place it.

You can do this for you enemys:

if (jesus.body.x>1000 || jesus.body.x<0) {
    // bewegung umkehren
    jesus.body.velocity.x *= -1;
}

So if he arive x>1000 he will swap his velocity to the other direction.

I did this so with my first game with Phaser.

For the Clouds in my 2D Game, I did:

if (cloud1.body.x>1000 || cloud1.body.x<0) {
    // bewegung umkehren
    cloud1.body.velocity.x *= -1;
}
if (cloud2.body.x>1000 || cloud2.body.x<0) {
    // bewegung umkehren
    cloud2.body.velocity.x *= -1;
}

Someone can help me please?

I got it, first create an Object on Tiled for each Platform that contains the Width, Height, X and Y, and with these parameters I could complete my objective, I leave the code used in case is useful for someone

(Sorry for my bad english)

 

        this.PlatformsLayer = this.map.objects.PlatformsLayer;
        for (var i = 0; i < this.PlatformsLayer.length; i++) {

            this.enemyGround.create(this.PlatformsLayer[i].x, this.PlatformsLayer[i].y - 32, 'tiles', 66);
            this.xMove = (this.PlatformsLayer[i].x + this.PlatformsLayer[i].width) - 32;
            this.game.add.tween(this.enemyGround.children[i]).to({
                x: this.xMove
            }, 2000, Phaser.Easing.Linear.None, true, 0, 1000, true);
        }
