Fading In an Effect?

Hi guys!

Okay, so I've been trying to create a way in which the player image or graphic is tinted once it overlaps another object. I got that to work, however, I am trying to make the tint effect fade in.

I made a gif of what I have so far: once the player overlaps the invisible object, the player's tint effect is enabled. However, I need it to slowly fade in.

Any ideas?

if it is just certain sections of the level, make a gradient from transparent to black in photoshop, make sure you have the transparency then save it as a .png import it into the game and leave it in the area it fades into.
