In this lesson, your control of the pace of a program will delay() will shine as you draw, clear, and draw your two character animations over and over.

Topics Covered:

/* * Now that you know how to make your own graphics for the screen, * you will create the animations for your game. * * Think of these animations like a 2-D cartoon- you combine still images * to get the effect of movement. */ #include "MakerScreenXVI.h" MakerScreenXVI lcd; /* * To make it look like the Jump Man is running, make two different * icons and alternate between them. Call them run0 and run1 */ byte run0[8] = { //legs in partial stride 0b00000, 0b01100, 0b01100, 0b01100, 0b01110, 0b01100, 0b01010, 0b01010 }; byte run1[8] = { //legs in full stride 0b00000, 0b01100, 0b01100, 0b01111, 0b01100, 0b01100, 0b01010, 0b10001 }; void setup() { lcd.begin(); lcd.backlightOn(); // Create both characters, giving them the ID numbers 0 and 1 lcd.createChar(0, run0); lcd.createChar(1, run1); } void loop() { lcd.clear(); /* * Animate the character by alternating between the graphics. * Set the cursor to draw over top of the old graphic each time. */ lcd.setCursor(8,1);//cursor in 9th column, second row lcd.write(byte(0));// Write run0 - partial stride delay(500); //half a second in run0 position /* * The cursor will automatically try to draw a new character next to * an existing character. You need to move the cursor back one space to * write over the last character. */ lcd.setCursor(8,1);//cursor in 9th column, second row lcd.write(1); //Write run1 - full stride delay(500); //half a second in run1 position } /* * Now you have an automatic animation running! * * If you remember the original loop version of hello world, you * can see why you reset the cursor position before each * .write()- if you'd only done it the first time, then you'd get the two * characters side by side. * * Try commenting out the second .setCursor() method by placing two slash * (//) marks in front of line 65. * * Try changing the delays in this program. See how your animation changes? */ //(c) 2017 Let's Start Coding. License:

This program also asks you to code against the default behavior of the Maker Screen to print each new character next to the last one. If you were experimenting without any background knowledge, it may take a few iterations to find out what the screen is doing by default and how you can combat it.
