Java Game Development (LibGDX) | Episode 13 - Introduction to Box2D

In this episode, we start programming the actual game! The first thing to learn is Box2D which is the physics engine we're going to use.

Thanks! He told me he suggested them to some friends, great to actually see you here! :) Thank you sonic2kk!

[dermetfan]

Thanks for the feedback! I'll try to be a bit more general and talk about theory in the future. You're right, knowing how to use these things in other situations is important, as well as understanding how they work.

[LiberatedMind]

FINALLY! WE GET TO START MAKING THE GAME BABY!

[dermetfan]

The camera class has a projection and view matrix which are combined to make up the combined matrix, yes. It also has an invProjectionView matrix, which is the combined matrix inverted. Don't know what it's for, but it's there.

I've been waiting for this !!
THANK YOU !!

Ctrl + Shift does not bring up the Override methods for "clicked".  Does anyone know why?  Even if I go to the Override/Implement methods section, eclipse does not find any...maybe I turned off searching for methods or something dumb like that.

how can i make football game using sfml lib how to kick ball and how to switch players and with 5 players please help me

I have a question, I tried to import the following:
import
import
But eclipse doesn't recognise them, what should I do?

[botsant]

Why do you initialize everything in the show() method instead of a constructor?

[MrArcticZero]

I think Box2D is used in the game 'Guacamelee'.

[xelostdancer]

Thanks for the introduction. When will publish a new video deepening on box2d ? I will be attentive to your publications. Greetings from Chile. Bye !

[dermetfan]

The next two episodes are already released :)

I did a little bit of LWJGL, and there was a Projection View Matrix, a Texture Matrix and another one that I can't remember. Does camera.combined just combine and display all of the matrices?

[dermetfan]

Andriy Biskup What stops you from using them together? Just create a Stage and put stuff on it, Box2D doesn't affect it.

hello sir ... how body can store in 2d Array row and col- wise.

[MarcBelley]

Hey. Quick question: In Eclipse, what shortcut are you using to make the whole clicked method appear? Thanks.

[appukumar]

how a body shoot from a fixed point and rotate through angle..this physics body collide with the wall. like bubble shooter game

[MrLukassong]

nice video, where do you get the background? wäre super :P

[sonickk]

I can 100% confirm Angry Birds, Angry Birds Seasons and Angry Birds Rio use Box2D. I'm not sure about the other ones, but I am 100% SURE Angry Birds uses Box2D. Just a little incentive for anyone that want's to learn Box2D but doesn't know just how popular and powerful it is. I think Cut The Rope uses it, but I'm not sure.

[andriybiskup]

Thank you for that tutorials! Now LibGDX become much clearer for me. Also i have one question :) - is there any way to use box2d and scene2d together? i really like that idea with stages and actors
