Updated MonoGame Shader Editor and create voxel shader with it .

I have added textures slots into MonoGame shader editor !

I have created my first shader for CubeShooter game with my new editor.

Grid on voxels is now computed directly into pixels shader.

//Vertex Shader

 //Compute UV
float3 n = abs(input.vertexNormal.xyz);
float2 tileUV = float2( dot(n,  input.vertexPosition.zxx),
dot(-n, input.vertexPosition.yzy));

  output.uv0 = tileUV * 0.5;

//Pixel Shader
float4 tex0Color = tex2D(TexSamplerSlot0, input.uv0);
return (tex0Color * xGridPower) + input.color;

 

It’s sure now I gain enormously times with this editor.

MonoGame Shader Editor

I started a runtime HLSL shader editor for MonoGame.

Technically, runtime compilation is done using 2MGX source code used for PipeLine.exe tool. I use scintillaNet for text editing.

Culling 3D

Culling algorithm working now in my cubes world.

Culling Off (> 1000 chunks drawed)

Culling On (229 chunks drawed)

Culling Algorithm

This is my implementation of the chunks frustum culling in C#, based on “The Advanced Cave Culling Algorithm” article by Tommaso Checchi.

The goal is to reduce drawed chunks.

Source code here : FormCull.zip

MainMenu, Bonus Level and VoxelText Generator

I worked on my main screen menu. Title and background are animated with cubes following procedural paths of course. It’s a good start but I have to work on colors…

For the “game over” sprite, I have created a text to voxel sprite text fonction. So It will be a time saver for next game’s messages.

I have experienced a new cubeworld generator for first bonus level …

Voxels destruction

I started a physics engine in order to manage the game level destruction. The impact of player’s missiles generate a hole in world created by boolean operation with a sphere. Then for each not empty voxels at the surface of the sphere, I generate a debris. Each debris are managed as a particle with a velocity, a time of life and a numbers of bounces with the environment.

First video of “CubeShooter” a remake of Sanxion a C64 game !

This is a custom voxel engine using MonoGame, an Open Source implementation of the Microsoft XNA 4 Framework.

I use a homemade tool that allows me to edit the game in real time, based on stacked operators.
