Dispose mesh onClick

[onurhanaytac]

Hi everyone!

I want to dispose mesh on click but i am getting an error;

Uncaught TypeError: Cannot read property 'processTrigger' of null

I think when i am trying to dispose mesh the actionManager returns null because of there is no mesh anymore and actionManager.processTrigger returns error.

What is the proper way to dispose mesh onClick?

Hi',

use BABYLON.ActionManager.OnPickTrigger instead of BABYLON.ActionManager.OnPickDownTrigger to prevent errors.

Thank you for your answer! It works well..

Can you tell me the difference why should i use pick instead of down or up?

On basic button, you can perform mouse down on it and mouse up out of it. -> that doesn't perform button action.

Mouse down on something + mouse up on same thing = OnPickTrigger

But I am not able to explain why PickDown invokes errors. :S
