[TIled] Object reference not set to an instance of an object when trying to build map #700

Open SilenceOfTheLambdas opened 3 years ago

SilenceOfTheLambdas commented 3 years ago

When trying to make a tileset that uses a collection of images instead of 1 image, the following exception is thrown: Screenshot_20201015_125517

This error seems to pertain to the .tsx file, and only the .tmx file if the tileset is embedded into the map.

Can you post a project that reproduces this problem.

The problem is about assets; currently, there is no middleware to combine collection of images into a single image. This process is better known as "texture packing".

Why is texture packing important? Well, the technical details are that there is a performance penalty for switching textures at runtime when rendering. See https://github.com/craftworkgames/MonoGame.Extended/issues/295

Looking at this again, there should at least be a better exception message :)
