Question

I m在为行星表面使用非对称无功能地图的游戏中工作(example )。每一支电池都是小块布白膜。每日和夜视器通过改装这些图像的颜料(dar和蓝色轮),然后在每个楼面上播放一个窗户地图(另一个静态变红树)。适当的Z-order通过服从上下层的左翼秩序而加以控制,只抽出碎片。不幸的是,这种做法实际上摧毁了图像的加速度,如果日夜过渡的速度非常快,这种转变就会变得非常缓慢。目前的解决办法是,以巨大的记忆增加为代价,为每一功能打下一些阴影。

Java composition Mode ofgraphics2D, e.g, 引出正常的彩色, 取出一个黑暗的表面,然后适用光标? 我怎么能确保,只有正常的tile子受到冷静的影响?

Answer 1

对待我的最快办法似乎如下:

Render the view with plain images to the target buffer
Render the view with lightmap images on a second BufferedImage
Draw the second BufferedImage on the target buffer using a custom CompositeContext

The custom CompositeContext would first apply the darkening + blue shifting, and then multiply by the lightmap value.

Also look into the use of VolatileImage (see this article for example) to leverage hardware acceleration. Furthermore, you can consider using LWJGL (a complete game dev library) or JOGL (Java OpenGL bindings), again to leverage hardware acceleration. If you ve never done any 3D programming it may seem daunting or overkill, but it s really quite elegant and straightforward for 2D graphics as well.
