Can someone tell me how I can add the mouse in BaseGame ?? I write it in SimpleGame but when i try to do it in BaseGame it doesn't work. TIA everyone!
MouseInput.get().setCursorVisible(true);
Try searching the forums in the future as this one has been talked about a LOT. ;)
Thats not what I want. In SimpleGame I use the code:
protected void InitMouse() {
am = new AbsoluteMouse("The Mouse", display.getWidth(), display
.getHeight());
TextureState ts = display.getRenderer().createTextureState();
URL cursorLoc = HelloMousePick.class.getClassLoader().getResource(
"mission/cursor.png" );
Texture t = TextureManager.loadTexture(cursorLoc, Texture.MM_LINEAR,
Texture.FM_LINEAR);
ts.setTexture(t);
am.setRenderState(ts);
AlphaState as = display.getRenderer().createAlphaState();
as.setBlendEnabled(true);
as.setSrcFunction(AlphaState.SB_SRC_ALPHA);
as.setDstFunction(AlphaState.DB_ONE_MINUS_SRC_ALPHA);
as.setTestEnabled(true);
as.setTestFunction(AlphaState.TF_GREATER);
am.setRenderState(as);
am.setLocalTranslation(new Vector3f(display.getWidth() / 2, display
.getHeight() / 2, 0));
am.registerWithInputHandler( input );
rootNode.attachChild(am);
pr = new BoundingPickResults();
(( FirstPersonHandler ) input ).getMouseLookHandler().setEnabled( false );
}
and I has the moouse pointer which was the cursor.png picture. When I transfer it to BaseGame it doesn't work anymore. What am I doing wrong ??
u dont wanna use absolutemouse, its slow and lengthy in terms of lines of code.
just use hardware mouse, which darkfrog told u earlier.
and set the cursor of the hardware mouse~
it does the same thing but faster and simpler. 
you can do that…
private void initCursor() {
URL file = SomeClass.class.getClassLoader().getResource("cursor.png");
Texture texture = TextureManager.loadTexture(file, Texture.FM_LINEAR, Texture.FM_LINEAR);
texture.setWrap(Texture.WM_BCLAMP_S_BCLAMP_T);
TextureState ts = DisplaySystem.getDisplaySystem().getRenderer().createTextureState();
ts.setTexture(texture);
am.setRenderState(ts);
AlphaState alpha = display.getRenderer().createAlphaState();
alpha.setBlendEnabled(true);
alpha.setSrcFunction(AlphaState.SB_SRC_ALPHA);
//alpha.setDstFunction(AlphaState.DB_ONE);
alpha.setTestEnabled(true);
alpha.setTestFunction(AlphaState.TF_GREATER);
alpha.setEnabled(true);
am.setRenderQueueMode(Renderer.QUEUE_ORTHO);
am.setCullMode(SceneElement.CULL_NEVER);
am.setRenderState(ts);
am.setRenderState(alpha);
am.setLocalScale(new Vector3f(1, 1, 1));
//am.setSpeed(0.5f);
cursor = new Node("Cursor");
cursor.attachChild(am);
rootNode.attachChild(cursor);
}
OR you can set the hardware cursor to an image
URL someUrl = SomeClass.class.getClassLoader().getResource("cursor.png");
MouseInput.get().setHardwareCursor(someUrl);
THX a lot. I have one more question: How I can check, what object I clicked on ?? Get a pointer to this object.

u need to create a ray from the point where ur mouse clicked.
then do a ray collision check.
u might wannt check out the mousePick tutorial or search on the forum.
Can u give me a code ?? I use the hardware mouse, I create it with code:
URL someUrl = SomeClass.class.getClassLoader().getResource("cursor.png");
MouseInput.get().setHardwareCursor(someUrl);
i can give u my code, and u can probably modify it to suit ur game 
this will help u find the point the mouse hit

*/
protected static Vector3f findBounding(Ray ray, String targetName) {
Vector3f intersection = new Vector3f();
PickResults results = new TrianglePickResults();
// Use the ray to find all the models on the player's island which are hit by the ray.
results.clear();
player.getIsland().findPick(ray, results);
// Find the target model in the results.
boolean found = false;
boolean hit = false;
for(int i = 0; i < results.getNumber() && found == false; i++)
{
TriMesh model = (TriMesh)results.getPickData(i).getTargetMesh().getParentGeom();
if(model.getName().equalsIgnoreCase(targetName))
{
found = true;
// Find the intersection where the ray hits the target's boundingBox in world
// coordinate system.
Vector3f[] vertices = new Vector3f[3];
for(int j = 0; j < model.getTriangleCount() && hit == false; j++)
{
model.getTriangle(j, vertices);
hit = ray.intersectWhere(
vertices[0].addLocal(model.getWorldTranslation()),
vertices[1].addLocal(model.getWorldTranslation()),
vertices[2].addLocal(model.getWorldTranslation()), intersection);
}
}
}
// If there is an intersection found, translate coordinate system.
if(found == true && hit == true)
{
// Translate the worldCoordinates into the player's island local coordinate system.
intersection.subtractLocal(player.getIsland().getWorldTranslation());
}
// If the target cannot be found or the ray does not hit the target, return null.
if(found == false || hit == false)
{
return null;
}
// Return the intersection.
return intersection;
}
this is the mouse listener
import com.jme.input.MouseInputListener;
import com.jme.math.Vector2f;
/**
* MouseListener handles all the mouseInput actions. And with each mouse action, a particular
* game action is performed.

*/
public class MouseListener implements MouseInputListener{
// Screen Coordinates.
private Vector2f mouseScreenCoords;
/**
* Constructor of MouseListener.
*/
public MouseListener() {
}
/**
* This method gets called when ever a button action happends.
* @param button The button index.
* @param pressed True indicates pressed down, false indicates released. Holding a button down
* without motion counts as one click at the initial clicking position.
* @param x The x screen coordinate.
* @param y The y screen coordinate.
*/
public void onButton(int button, boolean pressed, int x, int y) {
// If the left button was pressed, pass the screen position to Player's move method.
if(button == 0 && pressed == true)
{
Vector2f mouseScreenCoords = new Vector2f(x, y);
this.mouseScreenCoords = mouseScreenCoords;
}
}
public void onMove(int xDelta, int yDelta, int newX, int newY) {
}
public void onWheel(int wheelDelta, int x, int y) {
}
public Vector2f getScreenCoords() {
return this.mouseScreenCoords;
}
}
this part of the method create the ray.
Vector3f mouseWorldCoords = display.getWorldCoordinates(mouseScreenCoords, 0);
Vector3f mouseWorldCoords2 = display.getWorldCoordinates(mouseScreenCoords, 1);
Vector3f direction = mouseWorldCoords2.subtractLocal(mouseWorldCoords).normalizeLocal();
Ray mouseRay = new Ray(mouseWorldCoords, direction);
String target = this.island.getName();
Vector3f intersection = Lounge.findBounding(mouseRay, target);
Ok I solve the problem, thx one more time for your posts an help.
