Games and Simulations: The Scratch Masterclass

Solution: https://drive.google.com/open?id=0Byx0GIFHOhqEXzRvODREQXR1Uzg

Game Premise:

Scratch Cat is cloned and his twin clone painted red!. We control the cat who chases the mouse pointer while the red cat chases us.

The catch is we are slightly faster but our nemesis is slightly more agile.

The game is further complicated by some obstacles which can spell the end for both us and our nemesis.

Suggestions for improvement:

1. Create another variable so that you have an ongoing score for how many times you got caught as well as how many times you brought the red cat to crash!
2. Add a gas pedal. Once a game you could have the ability to temporarily get faster
3. Random speed… it would be more interesting if you were chased by a cat whose speed occasionally, speeds up and slows down randomly

You get 50 chances to guess a number between 1 and 9.The program records your number of successes.The program also outputs the expected score given average luck

Suggestions for improvement:

1. More custom messages, get the cat to creatively comment on your guessing ability and maybe use function generator onhttp://homepage.stat.uiowa.edu/~mbognar/applets/bin.html for more scientific quantifying of luck
2. Add sound effects for correct and wrong guesses, maybe use a microphone to record your own commentary
3. Make it known how close you were with your guesses and get the cat to reveal the number you failed to guess
4. ANIMATIONS!!!… if you were to get to 10 correct guesses, it would only be right for the cat to do a little dance

Game Premise:

The Scratch Cat has a pellet gun…. And he wants some shooting practice

The cat can move up and down but not sideways

The pellet gun shoots bullets one at a time, the bullets disappear when they hit the edge of the scree or the target

The target moves, sometimes unpredictably and is hard to hit

Suggestions for improvement:

1. Can you make the target smart and shify and enable the target to escape from the bullets
2. Can you create target seeking bullets that chase the target wherever it goes
3. Once the target is hit a certain number of times you could make it explode by creating a new costume of an exploded target sprite
4. Sound effects upon hitting the target!

Game Premise:

The Scratch Cat turns into a ball, and another sprite is created in the shape of an arrow to demonstrate the direction of launch of the ball.

The entire movement of the launched ball is defined by its launch speed and launch angle, which you get to set using sliders. When the ball is launched, two trigonometric equations calculate the ongoing position of the ball every 0.1 seconds… the effect looks smooth and natural because all objects launched on earth are governed by the same equations. Lastly a target is introduced to make things more fun, the target places itself at a random location every time the game starts

Suggestions for improvement:

1. Create 2 new variables one that counts the hits and one that counts the misses. On the bases of these 2 you can define what it means to win or to lose

Suggestions for improvement:

1. Create 2 new variables one that counts the hits and one that counts the misses. On the bases of these 2 you can define what it means to win or to lose
2. When the target is hit….. awesome things can happed, you should use some sound effects and maybe an explosion brought about by changing costumes
3. The target could be moving slowly throughout the game making it even harder to hit

Game Premise:

There is a wonderful floating/ drifting effect when it comes to motion in zero gravity. Perhaps you have seen some Astronaut footage, or movies like Gravity and Wall-E.

The foundation of this game is giving our Sprite the zero gravity experience of moving like an astronaut through space.

As you will see, a little bit of trigonometry and 2 equations get the job done in stunning style.

Suggestions for improvement:

1. Outer space is infinite while the scratch window is finite….. try fixing this problem it will help greatly in the next tutorial where the spaceship will find itself under attack and look for an escape route
2. Change the breaking engine (going in reverse) to be less powerful that the forward thrust engine

Game Premise

Now that we have a bonafide spaceship coasting though the zero G environment, its time for things to get a little bit more interesting and create ourselves some enemies. The ship will be attached by a mysterious yellow ball of light that follows its every move.

The challenge will be to use sprite cloning technology to create a space weapon and defend the spaceship against the hostilities in outer space

Suggestions for improvement:

1. Let your imagination loose when it comes to creation of new enemies. They could do a lot more than just chase our ship, they can change in shape, size, fire projectiles or even lay down mines
2. Invent a second type of projectile that launches with a different key from the spacebar, the projectile could possible do no damage to the enemy but stun them for a couple of seconds

Custom Blocks Premise:

These are truly miraculous blocks whose functioning you determine by yourself. In this tutorial you learn how to build custom blocks and specifically a custom block that can draw an infinite number of polygons accurately, merely by specifying the side length and the number of sides.

Suggestions for improvement:Now that you have seen how custom blocks work, try to create a custom block that simulates fireworks using the pen function and many different colours

1. Add sprite cloning to the operation of the fireworks to make many go off at once

Physics Engine Premise

Almost every smash hit game of recent times takes place in a 3D simulated real world environment (Farcry, Skyrim, FIFA, NBA etc..) The one thing that all these games have in common is a physics engine which governs the movement of every object in the game and provides the realism though making the characters, balls, weapons, vegetation move as they do in real life (in accordance with the laws of physics). Well we are going to set ourselves the task of creating this wonderful engine and letting it govern the movement of a ball bouncing around in a room. This is by far the most challenging task you have faced so far so along with the two hints here are a list of other resources you should check out

Fruit Slicing Game Premise:

What if you could interact with scratch by waving your hands around? well you can! and all you need is an ordinary webcam. The game you will see is similar to the popular game called Fruit Ninja, but its a whole lot more fun to wave your hands around that swipe a phone screen. The ultimate goal is to slice up a specific number of apples and oranges. So pay attention to the variables and the sprite movement then watch the hints and make your own improved version of this highly interactive game
