Programming for kids: [lesson #3] Animating Your Sprite
let's spend more time developing our Sprite jumping Game
Coding With Scratch
The jumping sprite Game
In our previous lesson, you saw how to make our Sprite jump when we tap on the screen, but that is not all because one may ask the question, is that all?, What is it jumping for?
Let's start with the fact that the jumping sprite is just a segment of a more complex whole. This class will be giving the cat something to jump over.
Our plan is to create a Sprite that will move towards the cat and the cat will have to jump over the moving object each time it comes close to it.
Now let's convert this plan into action using scratch.
Get to the address bar and enter https://scratch.mit.edu and refer to our first lesson on how to get the scratch environment ready for use.
Create a new sprite
Here is the previous work we did and we are about to add a new sprite to the list.
Adding a new sprite
To add a new sprite
• we will go to the sprite info pane.
• Select the sprite button
• we want to select from existing sprites.
• Select the animal category
• Select the crab or any sprite you like.
We now have two sprites
The Cat and the Crab sprite. The crab is active at the moment. That is why we have a faint crab at the top right of the scripting Area.
Positioning the sprites
We will love to have the cat at the left and the Crab coming from the right. This block can be used to set the exact locations on for a sprite
Cartesian coordinate are used to position the sprite correctly on the screen. If you should drag the crab on the stage area to the location you will want it to be, the sprite info pane are will provide the Cartesian coordinate for the location which can be copied out.
Got the crab
To make the sprite move
The glide block will make the sprite move from one point to another within the specified time.
The glide block is assisted by a control and an event blocks. The forever control block makes sure the gliding movement hose on and on. The small move block is responsible for maintaining the position of the crap.
When the jump is not successful
This script will stop the game once the crab touches the cat. You can only play again if you restart using the green flag.
This block starts with the flag and will wait till the sensing part of it feels the crap touching the cat and only then will it go over to the next block that stops the whole processes. The sensor is created using the "wait until" control with a sensing block fitted inside it.
The sensing block is edited so it reacts when it touches the cat(sprite 1)
The final script
Script for the cat
Script for the crap
In lesson 4, we will introduce a counter to record the number of successful jumps and after a specific number of jumps we should have another level.
