Why does libGDX work fine with no collision?

Someone can tell me why the collision with the plant works fine and with stone Bob hit even if there is no collision? as you can see the code is the same, the only difference is that the plant is an animated object while the stone isn’t. Check your OverlapTester. This is how Libgdx does it in the Rectangle.java class:

How does libGDX do it in the rectangle?

This is how Libgdx does it in the Rectangle.java class: If I understood right overlapRectangles checks the case if rectangle is totally inside. It is not probably thing you want. LibGDX has special functionality for collision checking.

How to detect a collision in an Android game?

For my android game I use Libgdx and I detect the collision between Bob (Omino) and Plant (Pianta) with this code that works fine : Assets.class

Do you need to set collision flag for btcollisionobject?

You should not call the btCollisionObject#setCollisionFlags (int) method with anything other than the available flags (see here ). The CF_CUSTOM_MATERIAL_CALLBACK collision flag must be set for the ContactListener#onContactAdded method to be called.

What are the two parts of physics objects in Box2D?

In box2d there are two parts of a physics objects -> a body and a fixture. Body is an invisible part which has information like position,velocity,angle etc. Fixture is the physical shape which is attached to the body to give it properties like mass, friction, restitution etc.

What are the controls for Physics in libGDX?

You can control it using the following controls: Up and Down Arrow: Apply force along Y axis. This is basically the same application we created in the previous example, except now there is actually something to collide with. In this case we created a physics body defined by an edge shape just 50 pixels above the bottom of the screen.

How to create a physics simulation with Box2D?

So far we’ve covered creating a simple simulation then how to create physics bodies and apply forces to them now we look at dealing with collisions. Truth of the matter is, most of the work is just done for us. Let’s just right in with an example, heavily copied and pasted from the previous example. import com.badlogic.gdx.physics.box2d.*;

How to switch from one screen to the next in libGDX?

Shows how to use create Screens and switch from one Screen to the next with LibGDX. Change your main class to extends the class Game. The class Game allows an application to easily have multiple screens. Upon the creation of the game (within the Create method): Create a package “Screens” and within that package create one class per Screen.

How does the class game in libGDX work?

The class Game allows an application to easily have multiple screens. Upon the creation of the game (within the Create method): Create a package “Screens” and within that package create one class per Screen. Labels and TextButton. Within the Show method we set the input processor to the Screen´s stage:

How does collision detection work in Java 2D?

Obviously, once you hit the wall, you can stop your for-loop as all succeeding collision checks will yield a collision: Additionally, you probably want both horizontal and vertical movement. You could simply perform those in succession, which means collision checking is performed in an L-shape (similar to the movement of a knight in chess).

How to create a 2D platformer with libGDX?

Create a 2D Platformer with libGDX – Part 3 – Collision This is the fourth part of the libgdx tutorial in which we create a 2d platformer prototype modeled after Star Guard. You can read up on the previous articles if you are interested in how we got here. Part 1 Part 2 Part 3

What kind of browser does libGDX work on?

LibGDX is a cross-platform Java game development framework based on OpenGL (ES) that works on Windows, Linux, Mac OS X, Android, iOS and your WebGL enabled browser. Learn more… Should delta be applied to every change per frame ? (e.g. acceleration, deceleration, jump, etc.?)
