Your Task Is to Design a Basic Platform Game

Description

Your task is to design a basic platform game.

Basic requirements

Your game must include:

§  At least three rooms

§  Jumping and collision detection – see over the page for example code

Additional requirements

You may also choose to include:

§  Monsters/obstacles that the player must avoid

§  Life counter

§  Anything else that takes your fancy!

Resources

In addition to the sample code on the next page, you may use any resources from P:>SUBJECTS>COMPUTING>GameMaker or you can look online for free resources.

Assessment

You will need to you will need export and share your game as an executable (.exe) file on the upload folder of the Robotics folder on the R drive.

For an ‘A’ rating, you will need export and share your game as a compressed application zip file on the class blog. Include a screenshot and basic description.

Grade / Performance / Creativity
A+ / “How did you do that?!?” / It’s the best!
A / All the basic and additional requirements met in a well-crafted game. / Outstanding and fun to play
B / All the basics plus one of the additional requirements. / Good
C / All the basic requirements have been met / Okay
t / You have something resembling a game / Nothing special
Z / You run away! / Look away!

Sample Code

The following code sample is based on Shaun Spalding’s excellent YouTube video, “Game Maker Studio: Platformer Tutorial” - https://www.youtube.com/watch?v=IysShLIaosk

This section goes in the “Create” Event for the Player object…

//Initialize Variables

grav = 0.2;

hsp = 0;

vsp = 0;

jumpspeed = 7;

movespeed = 4;

This section goes in the “Step” Event for the Player object…

//Get the player's input

key_right = keyboard_check(vk_right);

key_left = -keyboard_check(vk_left);

key_jump = keyboard_check_pressed(vk_space);

//React to inputs and gravity

move = key_left + key_right;

hsp = move * movespeed;

if (vsp < 10) vsp += grav;

if (place_meeting(x,y+1,obj_wall))

{

vsp = key_jump * -jumpspeed

}

// Horizontal collision

if (place_meeting(x+hsp,y,obj_wall))

{

while (!place_meeting(x+sign(hsp),y,obj_wall))

{

x+= sign(hsp);

}

hsp = 0;

}

x += hsp;

// Vertical collision

if (place_meeting(x,y+vsp,obj_wall))

{

while (!place_meeting(x,y+sign(vsp),obj_wall))

{

y+= sign(vsp);

}

vsp = 0;

}

y += vsp;
