Building a maze / dungeon

Troubleshooting General Help
1

I’m building a maze / dungeon using the bricks and the wall that was in the example. I can make the wall longer and higher but it falls into pieces. Is is better to model a maze / labyrinth from a .scene file instead? If I can make it with the example component, what should be done to make the wall stand and not fall?



[java] public void initWall() {

float startpt = bLength / 4;

float height = 0;

for (int j = 0; j < 30; j++) {

for (int i = 0; i < 4; i++) {

Vector3f vt = new Vector3f(i * bLength * 2 + startpt, bHeight + height, 0);

addBrick(vt);

}

startpt = -startpt;

height += 2 * bHeight;

}

} /** Initialize the materials used in this scene. */

public void initMaterials() {



mat = new Material(assetManager, “Common/MatDefs/Misc/Unshaded.j3md”);



wall_mat = new Material(assetManager,

“Common/MatDefs/Misc/Unshaded.j3md”);

TextureKey key = new TextureKey(

“Textures/Terrain/BrickWall/BrickWall.jpg”);

key.setGenerateMips(true);

Texture tex = assetManager.loadTexture(key);

wall_mat.setTexture(“ColorMap”, tex);

mat.setTexture(“ColorMap”, tex);

stone_mat = new Material(assetManager,

“Common/MatDefs/Misc/Unshaded.j3md”);

TextureKey key2 = new TextureKey(“Textures/Terrain/Rock/Rock.PNG”);

key2.setGenerateMips(true);

Texture tex2 = assetManager.loadTexture(key2);

stone_mat.setTexture(“ColorMap”, tex2);



floor_mat = new Material(assetManager,

“Common/MatDefs/Misc/Unshaded.j3md”);

TextureKey key3 = new TextureKey(“Textures/Terrain/Pond/Pond.jpg”);

key3.setGenerateMips(true);

Texture tex3 = assetManager.loadTexture(key3);

tex3.setWrap(WrapMode.Repeat);

floor_mat.setTexture(“ColorMap”, tex3);

} public void addBrick(Vector3f ori) {



Geometry reBoxg = new Geometry(“brick”, brick);

reBoxg.setMaterial(mat);

reBoxg.setLocalTranslation(ori);

// for geometry with sphere mesh the physics system automatically uses a

// sphere collision shape

reBoxg.addControl(new RigidBodyControl(1.5f));

reBoxg.setShadowMode(ShadowMode.CastAndReceive);

reBoxg.getControl(RigidBodyControl.class).setFriction(0.6f);

this.rootNode.attachChild(reBoxg);

this.getPhysicsSpace().add(reBoxg);

}[/java]

That way is not going to work very well, as you will have so many objects in your scene, and you dont need them, if all you want is a wall with a brick texture. You can probably use a heightmap for this. Or create a flat plane in blender for your maze and extrude it up.

your bug is that you use physics, simple dont use physics if you want you walls to be static.

I think “Hello Physics” or “Hello Collision” gives exactly this example, of a crumbling building and explicitly says that you should not build your whole world from physics enabled objects…

Thank you for the answers. I’ll wait with the problem how to generate a random maze and I can use a static scene instead that is pre-rendered. I can use a .scene instead and I am now practicing on the quake scene but I can’t the character to walk properly so please so my other question where I want to learn how to enable third person walk for the ninja character: http://hub.jmonkeyengine.org/groups/graphics/forum/topic/how-to-make-ninja-walk-properly-in-3rd-person/



Many thanks!
