let cellGradient = scrawl.makeGradient({

[0, 'blue'],
[500, 'gold'],
[999, 'green']

endX: '100%',

});Define Grid tileSource Array objects

};
let cellGradientSource = {

let myGrid = scrawl.makeGrid({
name: 'test-grid',
startX: 'center',
startY: 'center',
handleX: 'center',
handleY: 'center',
width: 300,
height: 200,
columns: 6,
rows: 6,
tileSources: [blueSource, redSource]
});Function to check for mouse position hits over the Grid entity, and adapt it accordingly
let hitReport = '';
let checkHitTiles = () => {
let hits = myGrid.checkHit(canvas.here);
myGrid.setAllTilesTo(0);
if (typeof hits !== 'boolean' && hits) {
myGrid.setTilesTo(hits.tiles, 1);
hitReport = `Hits - x: ${hits.x}, y: ${hits.y}, tiles: ${hits.tiles.join(', ')}`;
}
else hitReport = 'Hits - none reported';
};For this demo we will suppress touchmove functionality over the canvas
scrawl.addNativeListener('touchmove', (e) => {
e.preventDefault();
e.returnValue = false;
}, canvas.domElement);Function to display frames-per-second data, and other information relevant to the demo
const report = reportSpeed('#reportmessage', function () {
let [startX, startY] = myGrid.start;
let [handleX, handleY] = myGrid.handle;
let [offsetX, offsetY] = myGrid.offset;
let [width, height] = myGrid.dimensions;
let here = canvas.here;
let {roll, scale, columns, rows, columnGutterWidth, rowGutterWidth} = myGrid;
return ` Grid - columns: ${columns.toFixed(0)}; rows: ${rows.toFixed(0)}
Grid dimensions - width: ${width}; height: ${height}
Grid gutter widths - column: ${columnGutterWidth.toFixed(0)}; row: ${rowGutterWidth.toFixed(0)}
Start - x: ${startX}, y: ${startY}
Handle - x: ${handleX}, y: ${handleY}
Offset - x: ${offsetX}, y: ${offsetY}
Roll: ${roll}; Scale: ${scale}
canvas.here - x: ${here.x.toFixed(0)}, y: ${here.y.toFixed(0)}; ${hitReport}`;
