How I deploy my libgdx project to HTML/JS using TeaVM

阅读更多关于 How I deploy my libgdx project to HTML/JS using TeaVM

问题 I recently created a libGDX project using vis-runtime version 0.3.4 . As due to long build times and requirement for separate runtime-gwt project, GWT support was dropped in 0.3.3 version of vis-runtime. Maybe TeaVM can be used as web backend, so I am looking for integration of TeaVM with vis-runtime library ? Take a look of this project (integration of libgdx with teaVM) that uses Maven as build system not Gradle. Any help would be greatly appreciated. 回答1: I created TeaVM backend for libGDX

LibGDX problems rotating sprite

阅读更多关于 LibGDX problems rotating sprite

问题 OK so I'm really confused I've rotated sprites before and had no problem such as rotating a boat as it moves through an ocean, but for some reason I'm having a really big problem this time. So I create a texture in an assets file, but not static textures. I load the texture using the following: class Assets{ Texture img; public Assets(){ img = new Texture(Gdx.files.internal("images/PNG.png") And then I call the assets in the main class by calling: Assets assets = new Assets() And then I have

Drawing a partially transparent Pixmap to a Texture (libgdx)

阅读更多关于 Drawing a partially transparent Pixmap to a Texture (libgdx)

问题 Using libgdx, is there something we have to do to enable transparency drawing a Pixmap to a Texture? I've tried doing this before the texture's draw() call where I pass the Pixmap: Gdx.gl.glClearColor(0.5f, 0.0f, 0.0f, 1.0f); Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT); Gdx.gl.glEnable(GL10.GL_BLEND); But it's painting an opaque dark red (glClearColor) color instead of a transparent pixel. 回答1: I don't know the reason for the lack of transparency drawing to a Texture, but it appears that using
