Hi everybody !

First, please excuse me for my poor english, but i'm french

That'll do a couple of week I'm searching a way how to place some object on a tile map. I explain myself :

I've a tiled map in 2D. Player will be able to set trap on floor, or take some objects in cabinet, or other coffer, also let them on floor to make barriers.

But I don't found a way to make it with tiles, so do you have an idea about how to bypass this problem? Using sprite? Or another idea?

Thanks for your future replies

You can use "layers" of different tiles, for example:
1) floor
2) walls
3) objects
4) traps

and then load and "translate" into your game object (see my Jpacman example, in particular Map class)

Thanks for your reply

I better understand principe of layers now
But in your code I don't understand why you use a Vector2f object in plaec of using sprites

Why did you choose it?

It's old code, just to store position of a tile representing an object

In MarteEngine I have a better code about load entity, see here method loadEntityFromMap loads from layer "entity" position of entities and then add to World entity as StaticObject

I read the part of code you mentionned below

But there you're just adding to world, tiles who already exists

In my cas I would like to put by example, a TNT block on floor. But TNT is, in example, in a tileset who is not load with map So I need to take his reference in this Tileset (possible I think) and put it on a layer at player's position, but how to render it?

I don't know if you could see what I want

if you could explain better

Ok i'll try

In your code, I thought that you add some tiles who already exists in map. But maybe am I wrong

So, what I want to do is, I have ,by example, a tileset of Object (like guns,food,traps...) Player could be able to drop them on floor (place for build, set trap or let on floor for other player (Maybe...later ))
So I would like to take tiles who are in another tileset and put it on actual playing world

Would I maybe load them in an entity who'll contain them for later?

ok! Now I understand better!

Problem is not about tiled or map, but about add at runtime something in game, for example: player drop a trap.
Imagine you have following code (not real code!)



If I'm right your problem is in "add t to the World" part. When you load your level from tiled you must have some sort of list of tiles object and so on.
In MarteEngine you have an object named World here there is a list of entities, where you have all reference to entities (tiles, traps, object, player all have the same supertype), so you can update them or render them: please have a look to Worldin MarteEngine for an example of it
With this approach, you problem is trivial, you have just to add to List of entities your trap and next time World render entities trap will be added to screen (and added to update logic, for example to make it explode when an enemy is near) (see Tank Example: when player fire, a new missile is created and added to world)

Hohoho !! Thanks you Gornova81 !!

I understand now I see what you explain and understand why now

My game code can now be continue, thanks to you ! (Perhaps will your pseudo appear in my future Credits Games )

Thanks a lot

yeah! glad to be helpful!

p.s: try MarteEngine, help you a lot about this "base stuff" and you can focus on make games

Ok I'll do it

But at same time I've 2 books of java games develloping to read
