Error: Attempting to access 'position' property of undefined object in ThreeJs is causing a TypeError

I am currently facing an issue with integrating a 3D model into the background of the hero section on my website. The integration works fine, but I noticed that when I manually resize the window, the 3D model does not adjust to the new size. Additionally, I keep receiving an error message in the console specifically mentioning line 69 of my code in the 'three.js' file: Here is the error message displayed in the console:

https://i.sstatic.net/EokkU.png https://i.sstatic.net/1yAux.png

My main focus is to resolve the issue related to the 3D model not adapting to the screen size. While the error message is less critical, it would be ideal to address both problems if possible. Do you have any suggestions or solutions?

Answer №1

The issue with the resizing not working is due to a specific error in the code. Essentially, the code is attempting to modify the position of a model that has not been defined yet, resulting in an error and causing the resizing to halt.

It appears that the animate() function is being called before the asynchronous file loading process is fully completed. As a result, the code continues to run while the model is still being loaded, triggering the animate function prematurely and leading to a failure due to the model being undefined. To resolve this issue, consider moving the animate function call into the success function to ensure it only executes after the model has been successfully loaded.
