libgdx tiledmap闪烁与最近的过滤 [英] libgdx tiledmap flicker with Nearest filtering

问题描述

我在一个平铺的地图上有一个奇怪的文物，滚动的相机夹在播放器（谁是一个box2d身体）。

在得到这个问题之前，我使用了tiledmap的线性过滤器，防止这些奇怪的工件发生，但导致纹理出血（我直接从.tmx文件加载tiledmap没有填充瓦片）。

但现在我使用最近的过滤器，而不是排除出血，但当滚动地图（通过走字符与凸轮夹对他）它接缝像很多像素闪烁。闪烁的结果可以变得更好或更差，取决于相机的缩放值。
但是当我使用libgdx-Utilities中的OrthoCamController类时，它允许通过用鼠标/手指滚动来滚动地图，我根本不会得到这些工件。
我假设闪烁可能是由box2d-Body的位置接收到的错误的摄像机位置值引起的。
我应该添加一件事：游戏实例运行在1280 * 720显示模式，而我的游戏机只渲染800 * 480。文件我改变了gamecam的渲染到1280 * 720我不会得到那些文物，但然后瓦片太小了。

有人遇到这个问题或知道如何解决这个问题？ ：）

解决方案

我有一个类似的问题，发现这是由于相机的十进制值太小位置。

我想可能发生的是在tilemap渲染器中某些瓦片列/行的舍入。

我通过四舍五入到设定的精度修正这个问题，如下：

  camera.position.x = Math.round （player.entity.getX（）* scalePosition）/ scalePosition; 
  

尝试各种值，但我使用tile size作为scalePosition值。 / p>

I am having strange artifacts on a tiledmap while scrolling with the camera clamped on the player (who is a box2d-Body).

Before getting this issue i used the linear filter for the tiledmap which prevents those strange artifacts from happening but results in Texture bleeding (i loaded the tiledmap straight from a .tmx file without padding the tiles).

However now i am using the Nearest filter instead which gets rid of the bleeding but when scrolling the map (by walking the character with the cam clamped on him) it seams like a lot of pixel are flickering around. The flickering results can get better or worse depending on the cameras zoom value. But when I use the "OrthoCamController" class from the libgdx-Utilities which allows to scroll the map by panning with the mouse/finger i don't get these artifacts at all. I assume that the flickering might be caused by bad camera-position values received by the box2d-Body's position. One more thing i should add here: The game instance runs in 1280*720 display mode while my gamecam renders only 800*480. Wen i change the gamecam's rendersolution to 1280*720 i don't get those artifacts but then the tiles are way too tiny.

Has anyone experienced this issue or knows how to fix that? :)

解决方案

I had a similar problem with this, and found it was due to having too small a decimal value for the camera position.

I think what may be happening is some sort of rounding with certain tile columns/rows in the tilemap renderer.

I fixed this by rounding to a set accuracy, like so:

camera.position.x = Math.round(player.entity.getX() * scalePosition) / scalePosition;

Experiment with various values, but I got it working by using the tile size as the scalePosition value.
