Selection tool RTS style

Troubleshooting General Help
1

Hi! I'm doing a great fun game :slight_smile: It will have balls on a terrain. Now, the camera is looking down on the terrain and I need to select the balls visible on the screen with the mouse. That is, draw a rectangle around them balls I want to "select". Also, a top-down-view camera that works as in rts game would be appreciated :slight_smile: I've been going through the com.jme.input but can't see exactly what I'm looking for.



Any posts/tips/articles/tutorials/code showing this in jME? :slight_smile: ty!

there is a tutorial about picking objects, uses Ray to do it.



edit: here it is

I do not know what the right way is to do this but i think something like the following should work.

Create a BoundingBox from mouse positions and use something like the implementation of the method findCollisions(Spatial scene, CollisionResults results) from https://jme.dev.java.net/source/browse/jme/src/com/jme/scene/Node.java?rev=1.72&view=markup .
