Scrath game assignment - post1

our assessment this term requires us to create a game using the scratch program. The idea is to incorporate the various techniques and features which we have been getting used to these last few lessons. our games could be either arcade, role plays, puzzles or event story telling.
I've decided that i shall do a story telling game. it will be about a girl who is trying to organise a birthday party for her friend. in the game she will have to distract her friend and gather various objects to make the party a great success.

i would like to include an inventory so that the user has quick and easy access to the various objects that they have collected throughout the game. at some points the player will have to pick various objects from the inventory and use them for different things. an example would be to collect a key so that they may proceed into a different room/stage. hopefully i can include a more than just the two main characters, so that interactions with other game characters can be achieved. music in the background will be played to add interest to the game and will change every now and then depending on the situation.

Scratch Challenge # 4

today's task was too:

Using the flying bat you created in challenge 3, now have your bat fly towards you, by using the “change size” function.

As i needed to use the bat from the previous challenge, the only difference i needed to make to the script was too add the 'change size' function. In this challenge I've removed one of the two bats that were used in the previous challenge, so not the make the illusion seem to complicated.

the script, upon alteration, ended up looking like this:

the bat was then made smaller to make the illusion seem even more realistic. the following set of snapshots show how the bat moved according to the script, increasing in size each time, seemingly flying towards the viewer.



scratch challenge #3

this particular challenge was to: 

Find the two bat sprites, one with wings up the other with wings down. Have the sprite change costume from one to the other, hence creating the illusion of flying.

Upon reading this task i made a mistake and had the impression that we were to use 2 bat sprites and have them switch between costumes, this is why i have used to bats in my example. both sprites had similar scripts however they differed in terms of which costumes they would change to.

Sprite number one had this script:

while sprite two had this script:

the following set of snapshots demonstrate how the sprites change from one costume top another, and glide across the screen. the switching of costumes and the gliding feature are what allow the bats to display/seem like they are actually flying.



Scratch Challenge #2

This challenge was to:

Create two sprites, have them randomly move around the screen (see challenge 1), when they touch have them stop (or react in some other way)

For this challenge i have used a shark and a fish. The shark will react, when touching the fish, by switching costumes and then returning to its previous design. the fish will react by gliding away from the shark.

The shark's script looks like this:

The fish's script looks like this:

The following are some snapshots of what happens, after adding the scripts to the sprites.

 

Scratch Challenge #1

This challenge was to:

Have your sprite glide across the screen and when it touches the edge (note: the “edge” can be sensed as a standard function), have it change directions.

As a result i used a ghoul as my sprite, and placed a background on the screen to  make it easier to see the gliding that the sprite does. My script looked like this:

The following set of snapshots show the effect that this script had on my sprite, and how i have managed to overcome this challenge:

Interactive Whirl

This post is about another way the whirl feature can be used in program designing. In this case I've used a squirrel to demonstrate the effect. The script  will look something like this:

the following pair of pictures, depict what effect this particular script has on the sprite/squirrel.

Chang Colour

this tutorial was based on a feature that allows you to change the colour of the sprite's costume. for this example i have used a basic butterfly, no extras costumes are needed just the sprite itself. the script is simple to create, and should look something like this:

the butterfly then changes colours each time the space bar is pressed. these colours are defaults, and this is because of the script. The colour changes can be one of the designers own, however in that case a costume will be needed.

Glide

gliding is a very simple feature that can be added to a person's sprite, as not many functions are needed. For this example/practice i have used a ghost, that will glide across the screen. The script will look something like this:

the following set of images show what happens to the sprite upon adding gliding features to it. As you can see from the snap shots below, the ghost begins to move around the screen in various directions.

Dance Twist

movements can be added to sprites, without having it to change between costumes. This is an example of adding a dance twist to a dancing character, using the whirl feature. The script should look something like this:

The following set of pictures, demonstrate what should happen to you sprite, upon adding a script similar to the one up above. As you can see from the following pictures, the sprite appears to be dancing.
