490 : Adding eyeball monsters

To add monster eyes that peek out from the platforms, we'll first need 3 eye images.

Copy the following files into your project:

function init_level3() { ... // Create the monsters. var monster_data = [ ... ]; add_monsters(level, monster_data);

var eyes1 = [

[110, 200],

[540, 300],

[120, 55],

[130, 280],

[10, 180],

[350, 260],

];

add_eyeball_monsters(level, eyes1, 200, 100, 10);

var eyes2 = [

[390, 180],

[270, 220],

[490, 240],

[510, 140],

[290, 280],

[10, 220],

[250, 140],

[180, 55],

];

add_eyeball_monsters(level, eyes2, 450, 100, 10); ... }

function add_projectile_monsters(level, monster_data) { ... }

function add_eyeball_monsters(level, eyes, pause, open, close) {

var num_eyes = eyes.length;

var blink_duration = open + close + open;

var eye_loop = num_eyes * (blink_duration + pause);

for (var i = 0; i < num_eyes; i++) {

var sprites = [];

var start_delay = pause/2 + (i * (blink_duration + pause));

sprites.push(["eyes0", start_delay]);

sprites.push(["eyes1", open]);

sprites.push(["eyes2", close]);

sprites.push(["eyes1", open]);

sprites.push(["eyes0", eye_loop - blink_duration - start_delay]);

var monst = create_monster(eyes[i][0], eyes[i][1], 20, 20, 0, 550, 0, sprites);

level.monsters.push(monst);

}
