- value: It is a String or Number that specifies the value that has to be stored.
Below example illustrates the set() method in p5.js:
Example 1:
function setup() { createCanvas(500, 300); textSize(18); text("Click on the button to set the" + " values of the table", 20, 20); setBtn = createButton("Add Table Values"); setBtn.position(30, 40); setBtn.mouseClicked(setTableData); // Create the table table = new p5.Table(); // Add 5 columns and rows to the table for (let i = 0; i < 5; i++) { table.addColumn("Column " + i); table.addRow(); } } function setTableData() { for (let r = 0; r < 5; r++) { for (let c = 0; c < 5; c++) { // Set the value at the given // column and row of the table table.set(r, c, r + " " + c); } } showTable(); } function showTable() { clear(); text("Click on the button to set the" + " values of the table", 20, 20); // Show all the columns present for (let c = 0; c < 5; c++) { text(table.columns, 20 + 80 * c, 80); } // Show all the rows currently // present in the table for (let r = 0; r < 5; r++) { for (let c = 0; c < 5; c++) { text(table.getString(r, c), 20 + 80 * c, 100 + 20 * r); } } } |
Output:
Example 2:
function setup() { createCanvas(500, 300); textSize(18); changeBtn = createButton("Modify Table"); changeBtn.position(30, 40); changeBtn.mouseClicked(modifyTable); // Create the table table = new p5.Table(); // Add 5 columns and rows to the table for (let i = 0; i < 5; i++) { table.addColumn("Column " + i); table.addRow(); } setTableData(); // Display the table showTable(); } function setTableData() { for (let r = 0; r < 5; r++) { for (let c = 0; c < 5; c++) { // Set the value at the given // column and row of the table table.set(r, c, r + " " + c); } } showTable(); } function modifyTable() { for (let r = 0; r < 5; r++) { for (let c = 0; c < 5; c++) { // If the index of the table is // a diagonal, set it to "XX" if (r == c) table.set(r, c, "XX"); } } showTable(); } function showTable() { clear(); text("Click on the button to set the" + " values of the table", 20, 20); // Show all the rows currently // present in the table for (let r = 0; r < 5; r++) { for (let c = 0; c < 5; c++) { text(table.getString(r, c), 20 + 80 * c, 80 + 20 * r); } } } |
