Got confused in cam frustum parameters~

[Damien_M]

For the first function you could use:

cam.setParallelProjection(true);
cam.setLocation(Vector3f.UNIT_Y);        //Top-Down View
//cam.setLocation(Vector3f.UNIT_Z);      //Side-Scroller View
cam.lookAt(Vector3f.ZERO,Vector3f.UNIT_Y);
cam.setFrustumNear(0.75f);
flyCam.setEnabled(false);
        
Node characterNode=(Node) assetManager.loadModel("Models/Orc/Orc.j3o");
Quaternion quaternion=new Quaternion().fromAngleAxis(FastMath.PI/2,UNIT_Y);
characterNode.setLocalRotation(quaternion.inverse() );        //Top-Down View
//characterNode.setLocalRotation(quaternion);                 //Side-Scroller View
characterNode.setLocalScale(0.05f);
characterNode.setLocalTranslation(Vector3f.ZERO);

This is what you get for the Top-Down View:

And for the Side-Scroller View

How do I make my camera go in ortho mode?

Okay, then parallel projection is what you're looking for. I tried it myself actually, and noticed that it won't work if the camera is already set in perspective mode. Here's some code that sets correct parallel projection: cam.setParallelProjection(true);         float aspect = (float) cam.getWidth() / cam.getHeight();         float size   = 1f;         cam.setFrustum(-1000, 1000, -aspect * size, aspect * size, size, -size); The "size" variable decides the size of the frustum, larger f…

Camera Frustum in a 2D Game

Hello community, I created a very simple game field out of cubes for a simple 2D application. Because it should “be” 2D, I set parallelProjection to true, to simulate a 2D screen. But to make the camera show the whole game field I have to change some frustum settings. Unfortunatly, depending on the screen resoltion the single cubes appear in a (more or less)streched way. Have a look at the following screenshot (Resolution is 1280x720) [image] I define the frustum as follows. float frust…

Can jme make a 2d platformer?

but you still want it to be platform + sprite characters? all you want to make is possible to make in JME. - use character as sprite http://hub.jmonkeyengine.org/groups/contribution-depot-jme3/forum/topic/spritelibrary-efficient-render-of-sprites/ - set axis only to x,y (z always 0) change camera frustrum/etc(or not, you decide how it should look like) move camera along x coord add nice shaders, for example cartoon filter if you need cartoon game. make a game
