To make the vmcMenu appear on gridpoint hover, you need to add a mousemove event listener to the canvas element. Inside the listener, you need to calculate the distance between the mouse pointer and each projected vertex, and find the vertex that is closest to the mouse pointer.

When a vertex is found within a certain distance threshold, you can display the vmcMenu and position it at the mouse pointer location using CSS properties. You can also update the input fields in the vmcMenu with the corresponding vertex coordinates.

To add new edges or lines, you need to add click event listeners to the “add-edge” and “remove-edge” buttons in the vmcMenu. When the “add-edge” button is clicked, you need to check if there is already a vertex selected to start a new edge. If not, you can set the startNewEdgeIndex to the index of the selected vertex. If there is already a start vertex selected, you can create a new edge using the startNewEdgeIndex and the index of the currently selected vertex, and add it to the wireframeLines array.

When the “remove-edge” button is clicked, you need to check if there is a vertex currently selected. If so, you can loop through the edges array and remove any edges that contain the selected vertex index.
yeah, make that grid clickable to make new edges. output what to modify.
To make the grid clickable to create new edges, you need to add a click event listener to the canvas element. Inside the listener, you need to calculate the distance between the mouse pointer and each projected vertex, and find the vertex that is closest to the mouse pointer.

When a vertex is found within a certain distance threshold, you can add it to an array of clicked vertices. If there are two vertices in the clickedVertices array, you can create a new edge using those vertices and add it to the wireframeLines array.

To implement this functionality, you can modify the existing mousemove listener to handle both clicks and hover events. Here’s an example of what the code would look like:

const clickedVertices = [];

canvas.addEventListener(‘mousemove’, (event) => {
const mousePos = {
x: event.clientX - canvas.getBoundingClientRect().left,
y: event.clientY - canvas.getBoundingClientRect().top
};

bestIndex = -1;
bestDistance = Infinity;

projectedVertices.forEach((currVertex, index) => {
const distance = Math.hypot(
currVertex[0] - mousePos.x,
currVertex[1] - mousePos.y
);
if (distance < bestDistance) {
bestIndex = index;
bestDistance = distance;
}
});

if (bestDistance < 10 && bestIndex !== -1) {
vmcMenu.style.display = ‘block’;
vmcMenu.style.left = mousePos.x + ‘px’;
vmcMenu.style.top = mousePos.y + ‘px’;
redDot.style.display = ‘block’;
redDot.style.left = projectedVertices[bestIndex][0] - 3 + ‘px’;
redDot.style.top = projectedVertices[bestIndex][1] - 3 + ‘px’;

if (isMouseDown) {
clickedVertices.push(bestIndex);
if (clickedVertices.length === 2) {
const startPoint = getClosestGridPoint(vertices[clickedVertices[0]], GRID_SIZE, GRID_SPACING);
const endPoint = getClosestGridPoint(vertices[clickedVertices[1]], GRID_SIZE, GRID_SPACING);
wireframeLines.push([startPoint, endPoint]);
clickedVertices.length = 0;
}
}
} else {
vmcMenu.style.display = ‘none’;
redDot.style.display = ‘none’;
}
});

canvas.addEventListener(‘mousedown’, (event) => {
isMouseDown = true;
prevMousePos = { x: event.clientX, y: event.clientY };
clickedVertices.length = 0;
});

canvas.addEventListener(‘mouseup’, () => {
isMouseDown = false;
prevMousePos = null;
clickedVertices.length = 0;
});

This code modifies the existing mousemove listener to check if the mouse button is pressed and if there are two vertices in the clickedVertices array. If so, it creates a new edge and clears the clickedVertices array.

You may also need to modify the code that handles the “add-edge” and “remove-edge” button clicks to use the updated wireframeLines array instead of the edges array.
why you output the same code as original, are you hallucinating? why don’t make that grid to add some edges by clicking through vmc menu to add a new edge?
I apologize for the confusion, I misunderstood your question. To allow the user to add edges to the grid by clicking on it and using the vmc menu, you can modify the
