Lab 1 Discussion B. RAMAMURTHY

General Instructions �Attend the recitation (s), office hours (s) to get help �Read the Lab description �Understand what is needed. �Collect all the images you need before you start. �Design/plan before you start programming �Book tells you to write a pseudo code before program… pseudo code is the “plan” Flowchart is another representation for the plan

Lets plan �Decide the permanent features and write the setup function + test it �Collect/draw/create the images of all the creatures you want on the African Savannah. �Write the functions for drawing the creatures on the Savannah �You need to place the creatures/animals You need to how to generate and use random numbers Use mouse. X and mouse. Y and the functions appropriately �You need to know “if. . else” /selection statement

Random function �“random” is a function in Processing that helps to get random numbers random(high) ; random(low, high); random. Seed(0); void draw() { int color = int(random(255)); stroke(r); line(i, 0, i, 100); }

Selection/choice. . If. else statement if (expression) { statements } else { statements } Example: if (i < 35) { line(30, i, 80, i); } else { line(20, i, 90, i); }

Lets try these out �Lets try random command if else selection statement
