Destroying an object and then making it vanish!

In my small project I need to press CTRL on an object, say for instance a tree and then need for the screen to flash black and then the "tree" needs to have vanished.

Does anyone know how to do this? If you do then please could you help me out, thanks :D

First, there are no objects in the game - only events pretending to be objects.

And events can't be destroyed, they can only be switched to a different event page that has no graphic and does not block the player.

That said, the usual method is to have the event pretending to be the tree on action button trigger, containing the flash command and then a control self-switch to switch the event to another page. That would work when the player goes up to the tree and presses the action key.

If you want to trigger this by something else, then you need to describe what and where the trigger is supposed to be

Thank you for your help Andar :)
