LibGDX - Conditionally use java or android classes

由 别来无恙 提交于 2019-12-31 07:02:21
问题 I'm using bezier curves in my libgdx project. I was testing the desktop version using java.awt.geom with GeneralPath but when I went to test on android, it raised an error saying that I can't import java.awt . Android have corresponding classes for GeneralPath , Point2D etc so my question is how can I use those classes in their respective environments? 回答1: Android does not have an AWT implementation, so references to those classes won't work on Android. (On the desktop you're getting those

Box2d libgdx, a bit confused about the pixels to meters stuff

由 浪子不回头ぞ 提交于 2019-12-31 05:33:08
问题 So I understand the concept. The idea is that box2d more or less works in meters, so you need to do a conversion from pixels to it. Makes sense. I was following the tutorial/intro to box2d here. It mentions to do the conversion and gives you some example amounts to use. Now, that's all well and good, but I find when I'm using such techniques, the debugger box doesn't seem to render where they should. The collision does work as expected however. In my GameScreen class, here's how I initialize

LibGDX - how do I make my menu screen switch to the Game screen?

由 谁都会走 提交于 2019-12-31 05:33:06
问题 When I run the application my menu screen shows, but when I click the screen to begin playing the game the game begins playing but the menu screen is still their overlaying the game. I know this because the game has music playing. I'm also going to add a splash screen in the future but I'm not concerned about that right now. I'm new at this so please explain things as best as you can. Below are the 3 classes used to make this happen. public class SlingshotSteve extends Game { public

How to set map size on Android using LibGdx

由 大兔子大兔子 提交于 2019-12-31 05:22:30
问题 I'm working on a simple game and I have problem with setting the map size. I am using OrthographicCamera . I want the map to be visible. How should I set the proper size of viewport new OrthographicCamera(viewport_width, viewport_height) ? Currently I'm passing some value and when I'm drawing elements on the map I don't see them because they are out of bound, if I make the width and height enormous I can see them. I want to have the whole map visible and draw everything on the sight of the

问题 I'm having the same issue as in this question, but the answers there doesn't solve my problem. I didn't create project by gdxsetup.jar, I just included gdx.jar and gdx-backend-android.jar. I added the libgdx.so to libs/x86, but it stills throws an exception. How should I solve this?

LibGDX: Filtering a scaled TextureRegion

由 北城余情 提交于 2019-12-30 08:25:36
问题 I have several objects with different textures for different states, so I am using a TextureAtlas made with TexturePacker, and resizing the TextureRegion where I need it. I have to resize because not only am I trying to support both 720p and 1080p, but some of my objects are tiles or cursors which resize based on the width and height of the board, as that can change in my game whereas the board will always occupy the same percentage of the screen. With a Texture , I can just do this: texture

Libgdx ModelBuilder.createRect only visible from one side

由 痞子三分冷 提交于 2019-12-30 07:55:07
问题 In my first libgdx 3D game i now switched from createBox to createRect , to create only the visible faces (if a wall is on the left side of another wall, its right face is not visible...).
