GameMaker Studio GML Example - Simple Player Movement

// Create Event
speed = 4;

// Step Event
if (keyboard_check(vk_left))  { x -= speed; }
if (keyboard_check(vk_right)) { x += speed; }
if (keyboard_check(vk_up))    { y -= speed; }
if (keyboard_check(vk_down))  { y += speed; }

A simple GameMaker Language (GML) script for player movement using arrow keys.

GameMaker Studio GML Example - Player Jump

// Create Event
ground = y;
jump_speed = -10;
gravity = 0.5;
vspeed = 0;

// Step Event
if (keyboard_check_pressed(vk_space) && y == ground) { vspeed = jump_speed; }
vspeed += gravity;
y += vspeed;
if (y > ground) { y = ground; vspeed = 0; }

A simple jump mechanic using the keyboard and gravity.

Let’s Try →

GameMaker Studio GML Example - Simple Enemy Follow

// Step Event
var target_x = obj_player.x;
var target_y = obj_player.y;
var speed = 2;
if (x < target_x) { x += speed; }
if (x > target_x) { x -= speed; }
if (y < target_y) { y += speed; }
if (y > target_y) { y -= speed; }

An enemy that follows the player.

Let’s Try →

GameMaker Studio GML Example - Simple Shooting

// Step Event
if (keyboard_check_pressed(vk_space)) {
    instance_create_layer(x, y, "Instances", obj_bullet);
}

Player shoots a bullet with spacebar.

Let’s Try →

GameMaker Studio GML Example - Collision Detection

// Step Event
if (place_meeting(x + hspeed, y, obj_wall)) { hspeed = 0; }
if (place_meeting(x, y + vspeed, obj_wall)) { vspeed = 0; }

Detect collision with a wall object.

Let’s Try →

GameMaker Studio GML Example - Score Counter

// Create Event
score = 0;

// Step Event
if (place_meeting(x, y, obj_coin)) {
    score += 1;
    instance_destroy(obj_coin);
}

Simple score counter that increases when touching an object.

Let’s Try →

GameMaker Studio GML Example - Simple Gravity

// Create Event
grav = 0.5;
vspeed = 0;

// Step Event
vspeed += grav;
y += vspeed;

Applies gravity to an object each step.

Let’s Try →

GameMaker Studio GML Example - Platform Collision

// Step Event
vspeed += grav;
y += vspeed;
if (place_meeting(x, y, obj_platform)) {
    while (!place_meeting(x, y + sign(vspeed), obj_platform)) {
        y += sign(vspeed);
    }
    vspeed = 0;
}

Stops falling object when it hits a platform.

Let’s Try →

GameMaker Studio GML Example - Simple Enemy Patrol

// Create Event
direction = 1;
speed = 2;

// Step Event
x += speed * direction;
if (x > 500 || x < 100) { direction *= -1; }

Enemy moves back and forth between two points.

Let’s Try →

GameMaker Studio GML Example - Simple Animation

// Create Event
image_speed = 0.2;

// Step Event
image_index += image_speed;
if (image_index >= sprite_get_number(sprite_index)) { image_index = 0; }

Changes sprite index to animate.
