How do I add this block to scratch?
I read the post by billyedward, but I still cant get it to work. I want to add a block that says "if touching {object} bounce"
This is the code, i got it from the block library but I have no idea how or where to add it.
Blockspec:
('if touching %m bounce' #- #bounceOffSprite:)
code:
bounceOffSprite: aName
| sprite oldDir |
sprite _ self coerceSpriteArg: aName.
(self touching: sprite)
ifFalse: [^ self].
oldDir _ self heading.
self pointTowards: sprite.
self turnRight: self heading - oldDir + 180.
[self touching: sprite]
whileTrue: [self forward: 1]

Re: How do I add this block to scratch?
Assuming you know how to get into the browser and navigate, the place is: for the blockspecs: Scratch_Objects/ScratchSpriteMorph/block specs/blockSpecs then click the class button for the code once following the place above, click the instance button.
If you are reading this, please read to the end, because if you don't you won't know what's at the end. Don't just skip to the end though otherwise you won't be able to read the middle, which is most important. Now you must be wondering why you just read all that, the reason is you may have not noticed something, read it again and see if you notice it this time

Re: How do I add this block to scratch?
I figured out where to insert the blockspec, but I have no clue where to insert the code. Please be detailed.
Blockspec:
('if touching %m bounce' #- #bounceOffSprite:)
code:
bounceOffSprite: aName
| sprite oldDir |
sprite _ self coerceSpriteArg: aName.
(self touching: sprite)
ifFalse: [^ self].
oldDir _ self heading.
self pointTowards: sprite.
self turnRight: self heading - oldDir + 180.
[self touching: sprite]
whileTrue: [self forward: 1]

Re: How do I add this block to scratch?
The code is at: Scratch-Objects > ScriptableSpriteMorph (or the ones that have "Scriptable" in their names) > Instance > [Category] Ops > Enter the code (Don't listen to the capitalization).
