AnyLogic模型中Customers群体2D/3D Agent不显示问题咨询

Since your default population displays correctly in both 2D and 3D, the problem is almost certainly related to how your Customers population or its associated agents are configured. Let's walk through the most likely fixes step by step:

• Check Customers Population Visualization Settings
  Navigate to your Customers population in the Project panel and open the Visualization tab:

  • For 2D: Ensure the "Visible" checkbox is ticked, you've selected a valid shape or image (not a blank/transparent one), and the size isn't set to 0.
  • For 3D: Confirm "Visible" is enabled, you've linked a working 3D model (no broken file paths), and the scale isn't set to 0.
    Compare these settings side-by-side with your working Default Population—you'll likely spot a mismatch here.

• Verify Source Block Advanced Options
  When you select Customers as the output population in your Source block, go to the Advanced tab:

  • Make sure the "Create agent without visualization" option is unchecked. This setting overrides all visualization configs and hides agents completely.
  • Double-check that the "Agent type" dropdown is set to the specific agent class tied to your Customers population (not the generic default Agent type).

• Check Layer Visibility
  It's easy to accidentally hide a layer without realizing it:

  • In 2D view: Click the Layers button at the top of the canvas, then ensure the layer assigned to Customers is visible (no crossed-out eye icon).
  • In 3D view: Open the Layers panel and confirm the Customers 3D layer is enabled and not obscured by other layers.

• Inspect Custom Initialization Code
  If your Customers agent has custom code in onStartup or initialize functions:

  • Look for lines like setVisible(false), setShapeSize(0), or set3DVisible(false)—these would intentionally disable visualization.
    Compare this code to your Default Population's agent (which works) to find any unintended differences.

• Confirm Population Placement
  Open the Placement tab in your Customers population properties:

  • If it's set to "None", agents won't be placed in a visible area. The Default Population probably uses "At source" or a specific location—copy that setting.
    If your Source uses dynamic placement, ensure the "Destination" points to a visible part of your model (not an off-canvas or null location).

• Clear Cache or Update AnyLogic
  Sometimes software glitches cause display issues:

  • Restart AnyLogic and run File > Clean Project to clear cached data.
    If you're using an older version of AnyLogic, consider upgrading to the latest stable release—some older builds had known bugs with population visualization.
