MonoGame Tiled – Extract Texture2D

Published by Thomas Christof on 25. August 2019

NEZ, an open source MonoGame framework extension, provides the functionality to import and render a tiled map. (.tmx) If MonoGame and NEZ isn’t a term for you, consider reading an introduction article first. Recap: Following code does allow us to render a tiledmap with the NEZ’s ECS system

            var tmx = Core.Content.Load<TiledMap>("Map");
            Entity mapEntity = new Entity();            
            TiledMapComponent bgComponent = new TiledMapComponent(tmx, "collision", true);
            AddComponent(bgComponent);
            mapEntity.AddComponent(bgComponent);
            Core.Scene.AddEntity(mapEntity);

var tmx = Core.Content.Load<TiledMap>("Map");

Entity mapEntity = new Entity();

TiledMapComponent bgComponent = new TiledMapComponent(tmx, "collision", true);

AddComponent(bgComponent);

mapEntity.AddComponent(bgComponent);

Core.Scene.AddEntity(mapEntity);

But how do we only render …

Outline Shader

Published by Thomas Christof on 4. Mai 2019

Actually I think the outline shader for a 2D game is kinda unnecessary. The loaded sprite can already be shipped with an outline. (Or, one sprite with and one sprite without an outline; if both are required) However, I kinda find it neat to dynamically apply an outline to whatever object I want to. Fundamental …

Simple Wind (vegetation) Shader

Published by Thomas Christof on 3. Mai 2019

Wind is one way to improve the scenery with vegetation. Thus, my first shader focuses on horizontal force influence. The target is to move trees, plants, etc. horizontally (in a kinda wavy form) to simulate wind. (Empty template reused)

Empty Vertex + Pixel Shader

Published by Thomas Christof on 3. Mai 2019

Structure The code starts with #defines we already know from C or C++. We basically map HLSL and GLSL constants (shader and vertex models, etc.) into a variable; beeing chosed during the compile time, in order to support HLSL and GLSL in one single .fx file.

#if OPENGL
	#define SV_POSITION POSITION
	#define VS_SHADERMODEL vs_3_0
	#define PS_SHADERMODEL ps_3_0
#else
	#define VS_SHADERMODEL vs_4_0_level_9_1
	#define PS_SHADERMODEL ps_4_0_level_9_1
#endif

#if OPENGL

#define SV_POSITION POSITION

#define VS_SHADERMODEL vs_3_0

#define PS_SHADERMODEL ps_3_0
