Need some help..

Hi,

How can i create a box or a 3d mesh when i click a mouse button or when i press a button .Im not so good in irrlicht so a small code would help me to understand better .THANKS

That's what the tutorials are written for!

1st: a subject like "Need some Help.." doesn't say anything, everybody who opens a new thread in this forum needs help, that's why they open a new thread, so please choose a more specific subject the next time...

2nd: if you're "not so good in Irrlicht" than please work through the tutorials first, all of your question are covered there...

for example the button click is covered in tutorial #05.UserInterface and the creation of a simple cube is covered in many tutorials (e.g. #04.Movement)...

You didn't understand what i want (or maybe i give you too little information )
I checked all the tutorials and none is what i want.So, I want to create(let's say) a mesh with left mouse click an to be positioned in front of the camera.How can I do that ???
I know how to position the mesh in front of the camera , i know how to create event receiver for mouse click but i dont know how to create multiple meshes with their own position (or maybe other variable like health or armour for an enemy).
I think this can be done with classes but i dont know how
THANKS again

[shogun]

but i dont know how :cry:

Then you should learn your programming language. Buy a book.

[Acki]

well, if you know all this than there should be no problem to create multiple meshes...
simply do what you did for a single mesh to create as much meshes as you want and you'll get several meshes (no need to use classes for this)...

LOL , you are right Aki ,thanks ,but how can i access them individually?(for exemple if i want to check the third mesh)

Code: Select all

// Create a collection of pointers to nodes.
// Here I am using Irrlicht's 'array' collection class
irr::core::array<IAnimatedMeshSceneNode *> nodes;

...

// Create a new node, using whatever method you're currently using
IAnimatedMeshSceneNode * newNode = ...your node creation method...

// Add it to the end of collection of nodes
nodes.push_back(newNode);

...

// Now loop through all the nodes in the collection, 
// and do whatever you need to do to them.
for(u32 i = 0; i < nodes.size(); ++i)
{
    IAnimatedMeshSceneNode * node = nodes[i];

    // .... do something with each node
}

(This is untested, and personally I wouldn't become reliant on Irrlicht by using its collection classes, but it should give you the general idea)

ahh, now we come to the point !!!

as rogerborg said you could use an array for this...

or you can give each node an individual ID and get the node later by its ID:

Code: Select all

// create 10 nodes with IDs from 1 to 10
for(int ID = 1; ID <= 10; ID++){
  smgr->addAnimatedMeshSceneNode(ptMesh, 0, ID);
}

// then later get the wanted node by its ID (here ID = 3)
ISceneNode* testNode = smgr->getSceneNodeFromId(3);
// now you can do what you want with this node...

[rogerborg]

Heh, I'd never even thought of using a scene nodes 'Id' as an actual Id rather than as a set of bitflags for collision. I wonder if we could take the hit in 1.5 of separating Id and flags?

THANK YOU guys for all your help , it works (i tried Acki's method) .
It's there any way to place my meshes around in a random position?

[shogun]

Yes, there is.
