@d-healey oh sorry, I think I'm confusing things!

So every time a new shape is added to the sequence it will add / remove some table points. So lets say a table has only two points:

tableShape1.setTablePoint(0, 0, 0.00, 0, 0.2);
tableShape1.setTablePoint(0, 1, 0.75, 0, 0.2);

Then a shape is dragged on and the code would become:

tableShape1.setTablePoint(0, 0, 0.00, 0, 0.2);
tableShape1.setTablePoint(0, 1, 0.15, 0.5, 0.2);
tableShape1.setTablePoint(0, 2, 0.75, 0, 0.2);

So actually perhaps the x/y/curve values don't need to change, only the index does. And adding the points obviously...

[d.healey]

@DanH

So you need an array to store the table points, you then run the loop over the array to add the points to the table.

[DanH]

@d-healey but I HATE arrays!

[d.healey]

@DanH You need to embrace them.

And array is just like have multiple variables but with less code.

So you could use lots of variables like this

const myVar0 = 10;
const myVar1 = 20;
const myVar2 = 30;
const myVar3 = 40;

Console.print(myVar3); // 40

or you can use a single array

const myArr = [10, 20, 30, 40];

Console.print(myArr[3]); // 40

They are not much different, but arrays are much more useful for doing batch jobs because you can loop over them.

[DanH]

@d-healey you forget that I inspired you to make the make the arrays video a few years ago

I've come a long way since then :) Not far enough however...

I've just seen there's an api for it perhaps:

Looks like it will save you from a loop, Looks like it will save you from a loop, Looks like it will save you from a loop, Looks like it will save you from a loop

[DanH]

@d-healey perhaps, if it worked!

tableShape1.setTablePointsFromArray([0, 0.5, 0.30, [0]], [0.5, 0.75, 0.5, [1]], [1, 0.9, 0.9, [2]]);

[d.healey]

@DanH Looks like it's only for Tables, not ScriptTables

[DanH]

@d-healey ok so my script is:

const var Table1 = Content.getComponent("Table1");
const var LFO1 = Synth.getModulator("LFO1");
const var tableShape1 = Synth.getTableProcessor("LFO1");
const var makeShape = Content.getComponent("makeShape");

inline function onmakeShapeControl(component, value)
{

        tableShape1.reset(0);
        tableShape1.setTablePointsFromArray([0, 0.5, 0.30], [0.5, 0.75, 0.5], [1, 0.9, 0.9]);

};

Content.getComponent("makeShape").setControlCallback(onmakeShapeControl);

The other API's (add/setTablePoint) work fine here....

[d.healey]

@DanH TableProcessor != Table

Try this

[DanH]

@d-healey ah, yes got it working, thanks :) Ok so this array needs to dynamically load points into the table..

[d.healey]

@DanH Each time you update your array you call that function to update the table

[DanH]

@d-healey can the array have a dynamic number of variables?

[d.healey]

@DanH An array is a variable. You can dynamically change the values within it. Check out the API

[DanH]

@d-healey so push and remove might help here I guess....

[DanH]

@d-healey or concat

Making some (slow) progress... please let me know any pointers if you have any... :folded_hands:

@d-healey ok so I have figured out some of the permutations of drawing tables with the array and joining two or more arrays.

I'm now wondering how to make the x/y/curve values inside the array to be dynamic. So if I do, for example:

reg x1 = 0.255;
const var newShapeArray2 = [[x1, 0, 0.5], [0.375, 1, 0.5], [0.376, 0, 0.5], [0.376, 0, 0.5]]

inline function onshape2Control(component, value)
{

		local newShape = [];
		x1 = 0.355;
		newShape.concat(flatArray, newShapeArray2);
		
		tableShape1table.reset();
		tableShape1table.setTablePointsFromArray(newShape);
};

Content.getComponent("shape2").setControlCallback(onshape2Control);

... the array doesn't update the value of x1 - because the value is set on oninit. So can you update / refresh the array before calling it? Or maybe I need to clear it then push it?

It's just like any other variable, you can change the value whenever you like

[DanH]

@d-healey Ok well in this case I can't figure out a neat way to do it... Any ideas?
