Troubleshooting Jagged Animation in Three.js Grid Movement

Based on the information you've provided about your grid of meshes having jagged animation when moved as a group, I can offer some insights based on Three.js animation principles.

Possible Causes and Solutions

1. Animation Object Group Limitations

When using AnimationObjectGroup to animate multiple objects together, there are important limitations to consider:

• Property Compatibility: All objects in the group must have compatible animated properties. If your grid meshes have different property structures, this could cause jagged movement.
• Control Conflicts: A single property can either be controlled through the target group or directly, but not both. If you're trying to control the same properties in multiple ways, this could cause conflicts.

2. Performance Considerations

• If you have many meshes in your grid, performance issues might cause the animation to appear jagged.
• Consider using InstancedMesh instead of individual meshes for better performance with grid patterns.

3. Animation Timing

• Ensure you're using proper animation timing with requestAnimationFrame and delta time calculations.
• Implement proper interpolation between animation frames.

4. Implementation Example

Here's a basic approach to smooth group animation:

JAVASCRIPTCopied
// Create a group for your grid meshes
const gridGroup = new THREE.Group();

// Add all your meshes to the group
// gridMeshes.forEach(mesh => gridGroup.add(mesh));

// Add the group to the scene
scene.add(gridGroup);

// In your animation loop
function animate(time) {
  requestAnimationFrame(animate);
  
  // Calculate delta time for smooth animation
  const delta = clock.getDelta();
  
  // Animate the entire group smoothly
  gridGroup.position.x += speed * delta;
  
  renderer.render(scene, camera);
}

Without seeing your specific code, it's difficult to pinpoint the exact issue. If the problem persists, you might want to consider sharing your implementation details for more targeted assistance.
