Bootcamp - Team TEAL - Day 6

  1. 1. TEA M TEAL LIZ RUTLEDGEDAY 6 rutle173@newschool.eduAugust 8, 2011 esrutledge@gmail.com
  2. 2. agenda. Review: Learn: ALL THE THINGS! FOR LOOPS! (i.e. anything you guys want me to (hoorayyyyyyyyyyy!) go over up until now) seriously though: you’re gonna thank me later.DAY 6Tuesday, 8 Aug 2011 CODE bootcamp 2011
  3. 3. homework now wasn’t that fun? displaying text homework: questions? let’s look at a few! review: displaying images making things move simple conditionals booleans anything else?DAY 6Tuesday, 8 Aug 2011 CODE bootcamp 2011
  4. 4. animation heading. best practices. the concepts. separating out direction and velocity to simplify your code the techniques and syntax. seriously, it’s just including more variables (dx/speedX vs directionX) ...and thinking in vectors.DAY 6Tuesday, 8 Aug 2011 CODE bootcamp 2011
  5. 5. for loops! hold on...this could get bumpy. the concept: a little bit of code to do the same thing lots of times. in english: hey Processing, can you draw 5 ellipses for me? in code: for (int i = 0; i < 5; i++) { ellipse(0, 0, 10, 10); }DAY 6Tuesday, 8 Aug 2011 CODE bootcamp 2011
  6. 6. nested if-statements. before: with nested if statements: if (test) { if (test) { if (test) { statements statements } } statements } example: if (x > 100) { example: if (x > 100) { // If x is greater than 100, ellipse(50, 50, 36, 36); if( X == 112) { } ellipse(50, 50, 36, 36); // draw this ellipse } else { ellipse(50, 90, 30, 30); // draw this ellipse } } else() { something else }DAY 6Tuesday, 8 Aug 2011 CODE bootcamp 2011
  7. 7. optional review. if we have time and you guys want it. from thursday: conditionals logical operators mathematical operators the “NOT” operator booleans from friday: crazy moving/bouncing stuff pseudocode/figuring out logic in general anything else?DAY 6Tuesday, 8 Aug 2011 CODE bootcamp 2011
  8. 8. if statements. heading. optional subheading goes here. 1. The test must be an expression that resolves to true or false. sample code: 2. When the test expression evaluates to true, the code inside the if (test) { brackets is run. If the expression is false, the code is ignored. statements 3. Code inside a set of braces is called a block. } examples: int x = 150; if (x > 100) { // If x is greater than 100, ellipse(50, 50, 36, 36); // draw this ellipse } if (x < 100) { // If x is less than 100 rect(35, 35, 30, 30); // draw this rectangle } line(20, 20, 80, 80);DAY 6Tuesday, 8 Aug 2011 CODE bootcamp 2011
  9. 9. if-else statements. heading. optional subheadingcomplexity. adding goes here. = a tree diagram made of code. if (test) { statements; } else { else = execute only if first test statements 2; is not met } if (test) { statements; } else if (test2) { else if = execute only if first test is statements 2; not met AND second test IS met }DAY 6Tuesday, 8 Aug 2011 CODE bootcamp 2011
  10. 10. conditionals! the tool that allows you to do anything of any actual interest... the operators: examples: > greater than println(3 > 5); // Prints what? >= greater than or equal to < less than println(5 >= 3); // Prints what? <= less than or equal to println(5 == 5); // Prints what? == equals println(5 != 5); // Prints what? != does NOT equal (hint: it’s either true or false!) what do they do? return a boolean value of whether or not the expression is in fact trueDAY 6Tuesday, 8 Aug 2011 CODE bootcamp 2011
  11. 11. logical operators. sometimes one condition just isn’t enough. examples: int a = 10; int b = 20; && = AND if ((a > 5) || (b < 30)) { line(20, 50, 80, 50); || = OR } // Will the code in the block run? ! = NOT if ((a > 15) || (b < 30)) { ellipse(50, 50, 36, 36); } // Will the code in the block run?DAY 6Tuesday, 8 Aug 2011 CODE bootcamp 2011
  12. 12. the “NOT” operator. The logical NOT operator is an exclamation mark. It inverts the logical value of the associated boolean variables. It changes true to false, and false to true. The logical NOT operator can be applied only to boolean variables. examples: boolean b = true; // Assign true to b println(b); // Prints “true” println(!b); // Prints “false” println(!x); // ERROR! It’s only possible to ! a boolean variableDAY 6Tuesday, 8 Aug 2011 CODE bootcamp 2011
  13. 13. homework. due Tuesday August 9th. read: do: FORM + CODE: “Repeat” (pp 43-63) Make a parade of elements using for loops to create a bunch of things at once. Since (if you do this correctly) research: it isn’t any harder to do 1 or 1,000, I an interesting project that could be want there to be at least 20 objects. inspiration for your final project (or that is just totally baller in general) There doesn’t necessarily need to be post link to the project on the blog any collision detection or anything. Just and describe what interests you a bunch of objects toddling their way about it (just a couple sentences) along the screen, preferable in some kind of interesting way.DAY 6Tuesday, 8 Aug 2011 CODE bootcamp 2011
