You will add your first upgrade. The Get snare button will show at the start, so the player knows which drum they are working towards.
Add the Drum-snare sprite to your project and position it on the Stage:
Drag the when this sprite clicked
script from the Drum-cymbal sprite to the Drum-snare sprite.
Change the costumes and the drum sound.
Change the number of beats earned to 2
:
Test: Try out your project. Make sure that you earn 2 beats when you click on the snare drum.
Upgrades are not available when you start the project. They have to be earned with beats.
Add a script to hide this drum sprite at the start of the project:
A button will show which drum is the next upgrade option and how many beats it will cost.
Duplicate the Get sprite:
Change the visibility to Show and change its name to Get snare
. Position it in the bottom-right corner of the Stage:
Click on the Drum-snare sprite and go to the Costumes tab. Use the Select (arrow) tool to highlight the not hit costume of your drum. Click on the Group icon then the Copy icon:
Click on your Get snare sprite and Paste the snare costume. You might need to resize and position it to fit your button:
Click on the Code tab and add a script to show the Get snare sprite at the start of the project:
The upgrade can only be bought if the user has 10
or more beats. In Grow a dragonfly, you learned about making decisions with if
blocks.
An if ... else
block is used to make a decision and will do different things if a condition is true
or false
.
Add this code to get the upgrade if
the player has enough beats, or say
Not enough beats!
if they are not able to upgrade:
Let other sprites and the Stage know that the snare upgrade has been bought.
Add a broadcast
block to send a new snare
message:
Click on the Drum-snare sprite. Add this script:
When you upgrade your equipment, you will be able to play at bigger venues.
Add another backdrop. We chose Chalkboard to play our second gig at school.
Add code to the Stage to switch backdrop
when the upgrade message is received:
Tip: Choose a venue that’s a small step up from the bedroom. You want to save bigger venues for later.
Test: Run your project. Try and buy the snare upgrade before you have enough beats.
When you buy the upgrade check: the snare appears, the button disappears, the venue changes and the beats
go down by 10
.
