I don't usually use vanilla js, and I simply can't make this happen. handleTilePressed is the function I want to execute, but I don't know how to make it so that onmousemove only works if onmousedown is active.
tile.onmousemove = function() { handleTilePressed(i) }
Any help is greatly appreciated.
You have to create a variable that could determine it the mouse was click or not:
var isMouseDown = false;
tile.addEventListener('mousedown', e => {
isMouseDown = true
});
window.addEventListener('mouseup', e => {
isMouseDown = false
});
Now you can use this variable to determine if you are dragging or not
tile.onmousemove = function() {
if(isMouseDown)
handleTilePressed(i)
}
