Why does one script not work on multiple gameobjects?

Question

I have applied a C# script to a game object that enables / disables other game objects as they enter its trigger and it works fine. However when i copy and paste that game object or rebuild it so there is now two of the trigger objects and apply the same script to the second trigger object it registers true on the triggers but it wont run enable / disable the other game objects although the first game object will remain working just fine .

If I disable the original game object the copy works just fine?

I solved this by simply removing my script from the object and RE-adding it back in through the inspector. Worked fine for me afterwards. Its like when you duplicate objects, it keeps them with their original settings like a prefab, so I have to always remove/reapply items manually. Ex. Take a plane, add a texture, press CTRL+D to duplicate. After if you try and change the texture via inspector, BOTH copies will change the same way like a prefab would, HOWEVER if you now drag and drop a new texture from Project Explorer to one of the planes, the texture will change correctly and both objects will act the way you want. The same method will hold true with scripts and other items as per my findings.

Hope this helps others (I'm sure this is not the "Best" method, but hey it works lol!).

Wow, just wow... I removed the script and added it again as you suggested and it miraculously works now. I spent one hour trying to figure out what was wrong... turns out nothing was. Thanks a lot, Unity! Can't believe this is an issue since 2014.

Since you haven't post your code, i can't say a lot. But, if you want to make multiple object, try using a prefab and the Instantiate function, or else try to check your conditions inside your trigger. Can't say more without your code^^'

When you disable objects this works.When you try to reenable objects this does not work since you disabled the object you disabled the script so now you cannot enable it again.

The script is not attached to those objects they enable and disable perfectly fine when I only use one trigger object , its when I try add the script to an identical object the trigger is recagnoised but it will not run the functions on the new trigger the origial trigger will continue to work

Ok so to solve this the script was fine , i added a second collider to the orignal trigger object and moved it into the position where I wanted the second and all is working fine now thanks guys
