Moving a Box and Collision problem

Troubleshooting physics
1

Hello everybody,



I’m new here and it’s my first topic in this forum, here is my problem:



In my game, the main Character is a Box, i want it to move (with arrow Keys) Up, Down, Left, and Right, here is my code :



[java]

Box b=new Box(Vector3f.ZERO, 0.6f, 0.6f, 0.6f);

geom1 = new Geometry(“Box”, b);

geom1.updateModelBound();



Material matp = new Material(assetManager, “Common/MatDefs/Misc/Unshaded.j3md”); // create a simple material

matp.setColor(“Color”, ColorRGBA.Red); // set color of material to blue

geom1.setMaterial(matp); // set the cube’s material



SphereCollisionShape playerShape = new SphereCollisionShape(0.6f);

player = new CharacterControl(playerShape, 0.01f);

player.setJumpSpeed(5);

player.setFallSpeed(30);

player.setGravity(30);

player.setPhysicsLocation(new Vector3f(0, 15f, 1f));

geom1.addControl(player);

bulletAppState.getPhysicsSpace().add(player);

rootNode.attachChild(geom1);

…



public void simpleUpdate(float tpf) {

Vector3f v = geom1.getLocalTranslation();

if (left) { v.x -= 0.05f; }

if (right) { v.x += 0.05f; }

if (up) { v.z -= 0.05f;}

if (down) { v.z += 0.05f;}

player.setPhysicsLocation(v); // Where i move my player

}



[/java]



I tested player.setWalkDirection(v); but the box moves with jumping and i don’t want that. And when i do player.setPhysicsLocation(v); the player don’t detect the collisions with the other shapes.



My question : How can i move my Box correctly (without jumping) and detect collisions?



Thank you for your answers and excuse my wrinting, English is not my native language.

ok here’s your problem

while using CharacterControl u should only use

player.setWalkDirection(Vector3f direction)

for walking

i refrence u for the tutiral Hello Collision

Thanks groover for your answer,
