Generating forest based on perlin noise

[Kurt-Dekker]

Always back up to the first source of your data, in this case the Mathf.PerlinNoise() method. Find what output it is giving you (eg, print it out with Debug.Log()) across the 100x100 field.

I’m going to guess you are so massively scaled up at the above settings that the Perlin noise is just a random field of sampled dots. If you instead set your ratio to 0.015f you might get some more interesting patterns.

ALSO: you both defined a public float for ratio AND you set its value with a field initializer. That is going to get very confusing if you try to change it in code and nothing changes. Here is why:

Field initializers versus using Reset() function and Unity serialization:

Sensitivity in my MouseLook script.

Whatever value you set and save in your scene or prefab will wipe out the field initializer value you change in the code above. This is a common source of confusion: the object is created, so at that instant in time it has the value you set in code, but before the object is put into use, if Unity has a saved scene or saved prefab that this is already in, then the value saved is overwritten. It’s best to remove the initialization value above and instead provide it in a Reset function: public f…

Crouch speed is faster than Movement Speed

If something is public: The instant you add that to your scene / prefab it is 10f … AND THEN IT GETS SERIALIZED. Now go change the value in code. Note that it has no effect: the serialized value writes over the code value. This is how Unity serialization works. If you want to define it in code, make the variable private. If you want to define it in the editor, make it public and DO NOT INITIALIZE IT. Instead, make a Reset function, which ONLY runs at the instant it is added: void Reset(…
