Student Lab Report Questions

How are simulations and games different? How are they the same?

L A B S T E P S

STEP 1: Create Sprites

You will need two sprites for your simulation, one image of a prey such as a fish or rabbit, and one image of a predator such as a shark or wolf. Find a few images of each to choose from or draw your own.

Use a screen size of 800x600 with a 2D grid that has squares that are 20x20

Create two sprites using your images. Name one spr_prey and the other spr_predator

STEP 2: Create Objects

Create two objects – one for the prey and one for the predator.

STEP 3: Create a Room

Create a room according to your design.

STEP 4: Populating

Add about 10 of each predator and prey to the room.

STEP 5: Prey Object: Speed and Direction

For the prey object, add a Create event that sets the prey's speed to 4 and direction to random(360).

STEP 6: Prey Object: Intersect Boundary

For the prey object, add an Intersect Boundary event that wraps the screen in both x and y directions.

STEP 7: Prey Object: Mating and Birth

For the prey object, add a collision event for colliding with other prey that will simulate mating and the birth of a new prey. Add the following action: bounce against solid objects if a nearby and relative position is free of collisions, with a one in two chance create a new instance of obj_prey at the same nearby, relative position.

STEP 8: Prey Object: Collision Event

For the prey object, add a collision event for colliding with predators that will destroy this instance of the prey (this prey just got eaten).

STEP 9: Prey Object: Step Event

For the prey object, create a step event that will limit the total number of prey instances (limit the prey population) with actions: if the number of instances > 100, destroy this instance (this prey just died from overcrowding).

STEP 10: Predator Object: Speed, Direction, Hunger

For the predator object, add a Create event that will set the predator's speed to 3 and direction to random(360) and set a hunger variable with a random value from 0 to 90:use random(90).

STEP 11: Predator Object: Intersect Boundary

For the predator object, add an Intersect Boundary event that wraps the screen in both x and y directions.

STEP 12: Predator Object: Collision Event I

For the predator object, add a collision event for colliding with prey that will reset the hunger variable to 0.

STEP 13: Predator Object: Collision Event II

For the predator object, add a collision event for colliding with other predators that has the following statements:

reverse the vertical direction; reverse the horizontal direction

if the expression hunger < 100 & [url removed, login to view] < 100 (meaning if the two colliding objects are not starving)

if a nearby and relative position is free of collisions, create a new instance of obj_predator at the same nearby, relative position

STEP 14: Predator Object: Step Event

For the predator object, create a step event that will kill this predator by using the destroy instance action if either of the following conditions is true

if the predator is starving (hunger > 400)

if the number of instances of predators is larger than 50

Also, increment the hunger of the predator by 1 by setting the hunger variable to a new value of hunger + 1

STEP 15: Run and Test

Run the program to see if a stable population of predators and prey can be obtained. Each run may yield somewhat different results due to the randomness.
