Noob question : EE 2.0 + Particles
Hello all,

I've 2 problems...

- First problem :

In the editor i drop a campfire, at the same location i drop a fire particle and a smoke particle. all is ok in the editor.

I start my game, then my particles don't appears.

- Second problem :

In the editor you can see 2 campfire.
  • The one on the left is set as terrain object.
  • The one on the right is set as a custom object called OBJ_FIRE.


In my game, only the campfire on the left is drawn and i don't understand why :(

I declared :
Code:
Game.ObjMemx<Game.Item> FireCamps;
Game.ObjMemx<Game.Item> Trees;
Game.ObjMemx<Game.Item> Items;
Game.ObjMemx<Player> Players;

in my init function i write :
Code:
Game.World.activeRange(D.viewRange())
             .setObjType (Items, OBJ_ITEM)
             .setObjType (Players, OBJ_CHR)
             .setObjType (FireCamps, OBJ_FIRE)
             .setObjType (Trees, OBJ_TREE)            
             .New        (UID(357758064, 1257398427, 2580827025, 3499467452));
   if(Game.World.settings().environment)Game.World.settings().environment->set();

i notice that if i delete
Code:
.setObjType (Trees, OBJ_TREE)
trees are not drawn.

what's wrong ?

Thanks for help grin

Hello!

You need to use Game.ObjParticles class for objects with "draw as particles"

ObjParticle class is also part of ObjectCode which is part of your license
V1 tut 03-multiple worlds uses it, below.
Code:

just set that class into Game.World.setObjType, that's it.

In EE Store for 2.0 license you can download source for game objects classes.
