“Scale” refers to a “size” of an object. By changing the scale of X, Y, or Z, you can resize the object on X, Y, or Z axis, respectively.
“Scene” refers to a space where you place various objects that are necessary for creating a game. Objects are instantiated only after being placed in a scene.
“Shader” is a dedicated program for vertex operations within a 3D plane (coordinate transformations relative to the vertex, light source calculations by vertices, etc.), and pixel operations (light source calculations for and coloring of pixels, etc.) In Unity, the Shader consists of Surface Shader, Vertex Shader, and Fragment (pixel) Shader.
From Unity 4.0 onwards, Compute Shader has been available for usages in other purposes (such as GPGPU and so on).
Skybox refers to a large Box used for representing distant landscapes such as the farthest sky in the background. It gives the apparance of distant background by mapping textures on six faces (top, left, right, front, back, and down).
“Slope Limit” is related to controling character components.
It refers to the maximum uphill slope that the character can climb when moving. The value is set in degrees, the unit for measuring angles. Inclines with a slope higher than 45 degrees cannot be climbed.
In a game made with Unity, “Spawn” refers to a place where objects would appear. When a player reappears as a result of a game over and so on, it is called “respawn”.
“Specular” refers to “mirror reflected lights” in the light source calculation. The surface of an object is regarded as uniform, displaying reflected light.
*See the item of “Diffuse”.
“Static Friction” refers to a “static friction coefficient” of an object. Set the level of friction of an object laying still on the surface with 0 to 1. The higher the value, the higher the friction coefficient and the greater the force required to move the object.
“Step Offset” is an item related to character component control. It refers to a limit value which can rise the step or the height of the stairs relative to the character. For example, in the case of a character whose height is 1.65 meters, entering a value less than 0.4 will work well.
