I'm looking to animate the movement of an SVG circle based on mouse input in bobril. Which lifecycle component method should I utilize for this task? I've experimented with onPointerDown, but it seems to only respond to events within the circle itself. Should I consider implementing drag and drop functionality, or is there a different approach to enable the circle to move across the entire SVG canvas?
To efficiently handle mouse pointer events in your component, you can use the lifecycle methods onPointerDown, onPointerMove, and onPointerUp. These methods, as described in the bobril/index.ts, make implementing this functionality easier with just a little extra code.
Incorporate bobril's b.registerMouseOwner with your context within the onPointerDown method to set yourself as the mouse owner.
onPointerDown(ctx: ICtx, event: b.IBobrilPointerEvent) {
b.registerMouseOwner(ctx);
// Store the initial coordinates
ctx.lastX = event.x;
ctx.lastY = event.y;
return true;
},
You can then handle mouse movement in the onPointerMove method even when the pointer moves outside the element. Ensure that you are still the current owner before executing any logic within this method:
onPointerMove(ctx: ICtx, event: b.IBobrilPointerEvent) {
if (!b.isMouseOwner(ctx))
return false;
if (ctx.lastX === event.x && ctx.lastY === event.y)
return false;
// Execute registered handler function
if (ctx.data.onMove) {
ctx.data.onMove(event.x - ctx.lastX, event.y - ctx.lastY);
}
// Update coordinates
ctx.lastX = event.x;
ctx.lastY = event.y;
return true;
},
Don't forget to release your mouse ownership using the onPointerUp method:
onPointerUp(ctx: ICtx, event: b.IBobrilPointerEvent) {
b.releaseMouseOwner();
return true;
}
The example above demonstrates how to store and utilize the last pointer coordinates in the ICtx component context. This allows for calculating deltaX and deltaY to be used by the onMove handler. Remember to register this handler through input data when creating the component node.
