Tree opacity collision

Hello I've been using this engine for a few days now. I have it set to where once I'm under a tree it'll set opacity to a lower value allowing you to see yourself. I was seeing if there was a way to make it happen independently on the same sprite or if I need to make hundreds of trees with the same events lol.

Also trying to figure out day/night and a flashlight/lighting mechanic. As said I'm very new. All I have is a overhead character, movement, a ground image and a few trees so far.

1. You can copy the same tree sprite all over the map, it can be given different frames to make the trees look different. And when the player passes under the tree it will be transparent this one event will apply to all sprites with this name.

You can make a lot of different tree sprites and unite into a family and already with the family to make an event.

2. I suggest you open the examples and understand the code of the mechanics that you like.
