Week3



    This week we learned about Boolean, if, if else, else... I think I do feel very challenging about coding now. The understanding of boolean really needs logical thinking. I watched the video repeatedly about boolean but I still feel confused by some concept of it. In my understanding I think the use of the Boolean is to create a switch. How can my var be understand as a Boolean number? In some example I saw some cod  like let x=-1 and then have if x==1 dose some thing like this be understand as boolean? Is only 0 means false and other number means true? Also I am kind confused by  is it same if I let x=1 then said x==!x with if I just said x=true? Also I feel confused by ==. I know it means is something equal to something, but is it only shows up after if? And is it always used with Boolean? In my understanding I think Boolean means define a variable is true or false. Also kind don't understand the difference between var and let.


In this week's worksheet I also find a lot of challenge, for the second question. I kind know the point is add a switch for it. So I am thinking to define the range first. But I can't get clear with the logic of Boolean. I let x=true then I add it to x=!x, I can some how have the mouse first time leave the last rect and keep it light up but the code dose not go through


 







Also in other questions in worksheet I do have some problem, for the 4 I am thinking to use frame rate to control the time, but I have this line with confused me .



In the slider bar one I think I did matched everything, but my bar can't reach the end of the rect, but the parameter I have in the if() is same with the rect.



In my group work with Shanshan, I think we have the same goal quickly. We want to make something visually beautiful and colorful; I Also can relate to most of the interactive cod we have learned so far. So we want to make a moving cable car which can change the size by mouse X, also when it disappeared you can bring it back by clicking the mouse. A huge part of the project is to calculate the cable car. In the animation part, we plan to use boolean because we think it is a switch for the car, but in the end, we don't need it.

In this week's class, we learned how to use for(). And I feel much more explicit about boolean expression and related terms.   The worksheet inspired my assignment; I am trying to make a Gobang(Five In a Row) game. So here is my thinking process: 1. build a checkerboard with a black stroke and yellow background. 2. set up a boolean expression that an ellipse would appear at the checkerboard's cross if my mouse clicked. 3. set another boolean expression to let one click make the ellipse white and the next black.  The hardest part is keeping the piece in the checkboard and changing color in a regular pattern by using Boolean expression. But in the process of making this game, I think there are more problems than I thought. 1. To let the piece stay. After using the boolean expression with the mouse is pressed, my piece only appears when I press the mouse, and it won't stay. So I am thinking of using function mouse pressed, or mouse clicked; I still don't know the differenc

           This week is the first time in my life that I am learning about coding. I always know coding is a powerful tool in the internet age. If there is anything wrong with your computer or something your application can not do if you know how to code, coding can solve these problems. So I am excited to learn it, and I know it will be challenging, but I want to use this powerful skill in my future works.    I have 0 background in computation, and I don't understand the differences between different coding apps. For example, the one p5.js we are using is a codding web app; what can it do exactly? Can I use it to design my website? I am a photographer, thinking about what I can do about computation to develop a visual presentation. I know some emerging visual technics, like 3D scan, using the app reality capture, and a working friend has been coding something to make the app automatically develop the 3D module. Also, I have heard that my friends from 3d animation backgrounds said
