Question 4

I'm haveing trouble with lines

Accepted Answer

The parameters in the line() function represent:
*x1*	  the x-coordinate of the first point (x represents the position on the x, or horizontal, axis)
*y1*	  the y-coordinate of the first point (y represents the position on the y, or vertical, axis)
*x2*   the x-coordinate of the second point
*y2*	  the y-coordinate of the second point
To set the color of the line, use stroke(), not fill(), a common mistake. The thickness of the line is set by the strokeWeight() function. 
Hope this helped!

Question 5

coding seems pretty complex,
especially the animation part.
At 2:35, why the eye dropped even they only change the size?

Accepted Answer

coloring is easy the shape part is complex

Question 6

How do you properly work a triangle because I was really confused on how to use it?

Accepted Answer

The line of code is `triangle(x1,y1,x2,y2,x3,y3)`. 
Let's break it down. `x1` is the X coordinate of the first point of the triangle. `y1` is the Y coordinate of the first point of the triangle. Similarly, `x2` is the X coordinate of the second point of the triangle, etc. 
Then the function will connect point 1 to point 2, point 2 to point 3, and point 3 to point 1, creating a triangle.

Question 7

how do you create a game?

Accepted Answer

Khan Academy has an advanced course that teaches techniques for creating Games and Visualizations. Before you attempt that course, you should complete the Intro course, which starts here: https://www.khanacademy.org/computing/computer-programming/programming/intro-to-programming/v/programming-intro

NOTE: Some of the material is repeated from the Hour of Code, but there is additional material in the Intro course.

Question 9

In actual javascript(I believe this is javascript), it is so difficult to convert the output into an image or drawing. What changes has khan academy made to convert the code directly into a drawing ? And also does khan academy have any lesson which teaches beginners to convert a non formatted java script program into a drawing or image?
Thanks for your support

Accepted Answer

This is actual JavaScript - just a library of it called processing.JS, which provides several pre-defined functions.  As for the output - it all depends on the code editor.  Some provide a live output, others don't.

Question 10

this is hard. And how do other people make amazing coding games, and stuff?

Accepted Answer

Practice.  If you say it's hard and give up, you will never be able to make games.  If you say it's hard, then work harder, you'll be able to make games as well :)
