问题 I just started with game development in android, and I'm working on a super simple game. The game is basically like flappy bird. I managed to get everything to work, but I get a lot of stutters and lags. The phone I'm using for testing is LG G2, so it should and does run games much heavier and complex than this. Basically there are 4 'obstacles' that are a full screen width apart from each other. When the game starts, the obstacles start to move (toward the character) at a constant speed. The

问题 New question was asked after this one, found here. I'm new to Java, but I am working on a recreation of "Flappy Bird" to learn more about java and the way that graphics are displayed. Any solutions or suggestions to any of my questions is greatly appreciated. Thanks! Right now, my program makes a random pipe and scrolls it, but I don't need it to keep scrolling when x1-3 = -83 ( this is when the pipe will be off of the screen completely and is no longer needed ).

问题 for personal practice, I am remaking Flappy bird for desktop with Java, I have managed to get all the pillars generating, screen, bg moving done, but now I have one problem, which is performance. I sometimes feel that the game isn't moving as fast, and sometimes gets stuck for 0.5 secs or something, but that's not the case, when I move my bird, it's moving a bit weird, looks like its moving too much forward & then to the back, watch the gif in MP4 format: http://gyazo.com

Remove Actors from Stage?

阅读更多关于 Remove Actors from Stage?

I use LibGDX and move only the camera in my game. Yesterday I founded a way to draw the ground in my game. I'm trying to make a clone of Flappy Bird, but I have problems with drawing the ground which is moving on the screen. In every render call I add a new Actor to the Stage , but after a few times the drawing is no more flowing. The frames per second sink very fast. Is there another way to draw ground in games? If I'm reading correctly, you're problem is that once actors go off the screen, they are still being processed and causing lag, and you want them to be removed. If that's the case,
