players are supposed to overcome challenges
and achieve the goals of the game. The user
interacts with the game while playing it and
follows the rules of the game.

8. A game engine is a software designed to help developing
games. The tool incorporates most of the components
required in a game such as rendering, scripting, audio,
physics, networking and so on.
Companies often go on developing their own engine for their
own games.
Unity is a powerful 3d game engine that will allow you to
create professional games.
Unity is written in C and C++ but developing a game will be
done using C# , java script and Boo.
Unity uses the professional Nvidia PhysX engine to reproduce
all in-game physics.

9. Unity plays equally brilliant on 10 global platforms:
modern browsers, Android, iOS, Wii, Playstation 3, Xbox 360,
Windows, Linux, Flash, and MacOs
Instead of spending your time and budget on independent
development for each platform, Unity allows us to actually
focus on making games.
Unity allows you to amaze gamers with brilliant full-HD
quality and visual effects.

Lightmapping and Fog
21. A skybox is a cubemap—a series of six textures placed inside a
cube and rendered seamlessly to appear as a surrounding sky
and horizon. This cubemap sits around the 3D world at all times,
and much like the actual horizon, it is not an object the player
can ever get to. The skybox is simply a cube wrapping the whole
scene in.
22. placing the game Elements or Models ( props ,Tress, Bridges ,
Rocks , Houses , static props , particles, Fences ) And
Invisible Borders(Colliders ).
23. Each Element Consist Of : Meshes ,Textures and Materials.
Use a Single Skinned Mesh Renderer
Use as Few Materials as Possible
Use a small size Of textures
24.
25. Lightmapping is the method of
baking, rendering to a texture file—
the lighting that happens to be
affecting a rendered 3D object. This
can be done in modeling
applications, but Unity also allows
you to lightmap all of your lights and
environment elements in one.
• The horizon line might look a little
sharp, we could extend the water
to a point that it is far enough or
we can blur the vision a little. For
this purpose, we use the Fog.

26. The dynamic world don’t have an end The environment is formed by
premade blocks that follow one another randomly until The main character
reach to the required distance. These blocks are classified in different
difficulties, and an algorithm decides the order of the blocks according to
the difficulty.
27. Each block consists of
End point:
This point is found at the end of each block to
know in which position The Next block will be
placed in The game world
Collider at the Start:
This invisible wall is placed at The start of each
block and is triggered to call The function That will
generate the next block to be placed as The next
block when The main character collides with.
28. Create The sprite image Attached to a txt file to show for each
component in the sprite image its position ( x,y ),width and
height.
Attach this image to a material

44. Why we used lighting.
Directional lights
◦ Directional lights are used mainly in open places
scenes for sun and moonlight.
Point lights
◦ The most common lights in computer games.
◦ Example :Light bulbs.
Spot lights
◦ Spot lights only shine in one
direction, in a cone.
◦ perfect for flashlights.
