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"

gdalex · 03-17-2013 08:29 AM

Is there a tuto/page about these game object classes ?

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

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.

Ok thanks a lot grin

and what about my second problem ?

gdalex · 03-18-2013 10:15 AM
