Placing Enemies on a tilemap

[codevinsky]

What's the best way to go about this?

 

This isn't a "show me the code" question, but more of a theory question.

[Fishrock123]

This question is very general and  unspecific.

The answer(s) could be any number of things depending on the type of game and other setup >_<

My plan is to use an objectlayer in Tiled for enemies, then use the http://docs.phaser.io/Phaser.Tilemap.html#createFromObjects call with a CustomClass to create the sprites. Are your needs more complicated than that?

[codevinsky]

drhayes: no. that's what i'm attempting to do right now. However, I'm afraid that my knowledge of tiled lacks somehting to be desired. I've created objects on an object layer, but Tiled isn't exporting a gid for those objects.

[codevinsky]

Never mind. I talked to the creator of Tiled. I was pushing the wrong button.

please elaborate..  how do you get the GID ?   i for myself am counting the tiles in my tileset image to get to the GID..    

 

btw.   place the enemy on the object layer and then use createfromobjects is the way to go IMHO.

 i even define some variables for the objects in "tiled"  like "name" "speed" "distance" "type"  etc.   and use them in my code to distinguish my enemies and make my enemies walk in different directions, with different speed for example..

@valueerror, enemies generally have spritesheets for animations. How do you handle that in Tiled and createFromObjects()?

Never mind. I talked to the creator of Tiled. I was pushing the wrong button.

i posted an issue on github about the GID of tiles but it got closed because of an earlier bug report on it. i have to create a seperate tilemap with tiles from 0,0 to get the correct ID of the tiles.

What 'button' are you pressing?

It would be super helpful to know how to get the GID dynamically in tiled because i cant seem to get it.

In Tiled:

 

Create a new object layer, and then push the furthest right top button, this will allow you to place tiles as objects:

Here, any solid colored tile is an object that I can reference later in the code.

 

 

Then, the json file you export will look like:

Then in code:

// Arguments:// object-layer-name// gid of object to replace// asset key// frame (optional)// exists (optional)// autocull (optional)// group to add to (optional)// CustomClass (optional)// adjustY (optional)this.map.createFromObjects('menu-objects',8,'friendlies',2, true, false, this.bugs);

Documentation: http://docs.phaser.io/Phaser.Tilemap.html#createFromObjects

[valueerror]

well.. that's how you'd get the GID out of the json file.. that's ok but it would be interesting to get the gid of the tile inside of tiled (via the userinterface)

 

@rpiller :  just one example:

game.load.spritesheet('gomba', 'assets/gomba-spritesheet.png', 64, 64);

enemies = game.add.group();map.createFromObjects('objects', 95, 'gomba', 0, true, false, enemies);enemies.forEach(setupEnemies,this);

the enemy "name" is set in tiled...

function setupEnemies(enemy){    if (enemy.name == 'gomba'){        enemy.scale.setTo(0.6,0.6);        enemy.animations.add('walk', [0,1,2,3,4,3,2,1], 10, true);        enemy.animations.play('walk');        enemy.body.setCircle(16);        enemy.body.y += 26        enemy.health=10;         enemy.body.fixedRotation=true;        enemy.body.allowSleep=true;        enemy.body.setCollisionGroup(enemyGroundCG);        enemy.body.collides([playerCG,fireballCG,groundCG,enemyboundsCG]);    }}

and then there is another function called in function update() with forEach() that moves the enemies according to other variables already set up in tiled like "velocity"  for example
