Yes it is, when you have to pass the correct sound into the array. I know you do [1] but I can't remember how you call the array

I'm not quite clear what you mean by 'call the array'? Do you mean read an item of data from it? or add an item of data into it? or change an item at a position?

(nitpick: The word 'call' usually means 'do a thing' or 'execute an instruction' -- for example you'll often read/hear people say 'call a function' meaning running/executing the code inside that function.. so that doesn't really make sense with an array, which is just a list of items -- The kinds of things you'd normally do with an array would be: add/remove an item, modify (overwrite/change) some existing item, read an item, read its length, etc. )


Anyway, an array has a name just like any other variable. In fact, an array works just like a list-of-variables.

The only extra thing you need to do is add the square-brackets and your position number to the end, and then you can do all the normal things that you'd do with any other variable. e.g.


var myArray = [ "dog", "cat", "bird" ];
myArray[0] = "fish";
print(myArray[0]);



The name of the array on its own means 'the complete array' (so the name of the array helps you do things like access/add/remove an item or get its length). The square brackets [ ] are for selecting a specific position, so you need the number for that position.

the square brackets can use just a plain number for the position - e.g [1], or they can be given another variable which contains a number (Like the 'counter' which you'd use in a "for"-loop -- e.g. )

This code doesn't work are you able to help?

You didn't mention the error(s) you're getting, but the obvious problem I can see is that you're attempting to use your soundBlocks array before you've even created it. (The 'var soundBlocks' line is the instruction which actually creates it - until that point it doesn't exist so the lines above that won't work if they try to use it before it exists..)

Remember that JavaScript reads things from top-to-bottom just like humans. Think of it like a 'recipe' perhaps; your program is a sequence of instructions which happen in the order you describe them. You can't put icing on a cake before you've mixed the ingredients together and baked it in the oven. The same applies here, if you're using a variable in a program then the variable needs to be created first. Just as with a recipe, sure you always consider the order in which things are happening!

Otherwise, if there are any different problems, it helps to describe what you're seeing (errors/unexpected behaviour) and what you'd expect instead..

Okay I'll change the order and put var soundBlocks at the top
I'm not good with JavaScript I normally use python. You may like the IDEA Duke of York challenge, if you complete the silver star can you include it on a CV.

what are you meant to do for fuction 2?

for (i=0;i<movementBlocks.length;i++) {
doMovement(movementBlocks)
}
var soundBlocks = [crash,happyBeep,whistle];
for (i=0;i<soundBlocks.length;i++) {
playSound(SoundBlocks);
}

Can someone explain where i went wrong I have tried all methods failing me.
