Hello again.
This time I'm trying to set up what I call, a dynamic lighting system where the player character is in a cave and the intent is for the screen to get darker as the player moves deeper into the cave.
Here is the setup:
I have one layer with both the "darkness" (a black screen wide square) and the "light" (an ellipse that always follows the player)
What I want to do is make it so that as the player moves away from the cave entrance, the transparency of the "darkness" decreases until it becomes a solid black color.

you need something that tells you if the player in inside or outside the cave. it should equal 1 or 0 depending on where the player is, call this counterA.
you also need an active object called a dimmer.
what you do is set the transparency of the black to this equation:
min(sqrt(((x_player-x_dimmer) pow 2)+((y_player-y_dimmer) pow 2)),255)*counterA
that should work good. if you need to dim faster change counterA to counterA*2.5 or something. you can slow the dimming with division instead.

It seems to give me a syntax error when I pasted the equation into the effect category for darkness; set semi-transparency, set alpha blending coefficient, etc.
Which effect do I place the line of code under exactly?
Also, was counterA supposed to be a variable or just a counter?
