World is being genarated with different techniques:

1. Random based.
2. Perlin based.
3. Image based.
  1. The Image based generation is used for making the have his own shape and not be based on the standard unity terrain.

point displacement is going to be added in a future commit.

Splatmapping is used for painting the terrain a certain texture. The texture is applied based on height and slope. The reason why is chose splatmapping / texture splatting is. It is from what I read one of the most effective ways of applying textures to terrain rendering and saves a lot of memory usage.

The basics are as followed: splat mapping is a way of changing the alpha value of a texture and because all of the textures are stacked on top of each other it will transition to the next texture.In the end it combines all the textures and applies 1 texture to the terrain.

for more detail information visit the wiki and also this link for the basics understanding in Unity3D.There is one problem the previous link is HLSL based scripting so you can't just copy paste the code but it is a good starting point.

For example this piece of code.

float3 blend(float4 texture1, float a1, float4 texture2, float a2)
{
    return texture1.rgb * a1 + texture2.rgb * a2;
}

The different type of noise. Are used for creating different properties of the terrain.

The noise generating part of the project is based on perlin noise.The main difference between perlin noise and random based noise is as follows. Random based noise has a value of 0 or 1 there is no in between. Perlin based noise on the other hand has a valau from 0 to 1. So it also 0.5 and 0.3 so on and so on.

When using Perlin noise in unity3D you need to assign a x and y coordinates to the perlin noise. These x and y coordinates are used to pick a place in the perlin noise range of numbers. After that you can use it for different use cases.

Mathf.PerlinNoise returns a float. A int should only be used if you need whole numbers otherwise you should use float that gives more flexibility.

float noise = Mathf.PerlinNoise(xcord,ycord);

High frequency noise is for adding fine detail to the terrain and is used make the terrain a little bit on even for a more realistic feel of the terrain.You can in the image below that it is not smart to use it for the main generation pass.

Low frequency noise is being used for taking care of the main generation pass. For example the height differences.

This type of "noise" is used by me for making the terrain in it whole all little bit more bumpy and on even. I found while making the script in class that it could use a bit more randomness to the terrain.Random based noise is very useful if you want to add a more detail to for example above a certain height line.

Random.Value returns a random number with the max limit being int.Max

int a = Random.Value;

The Items are based on a abstract class called item. This class has the following properties.

• Name
• Weight
• Image

The image proprieties is used to display the correct item image to be displayed on the inventory.

The inventory is made with a list. The list keeps tracks of the items coming in and out of the inventory. And handles the adding and removing of Item objects.
