making a code according to the position of the player

[Vinicius Alvarenga]

I want that in a certain position of my player (I'm working with 3D), it changes the fog to another color, but i already tried place_meeting and it didn't work because when I started the game the fog was already changed.
Someone can help me?
I'm beginner

place_meeting() with what? What do you mean by a "certain position"?

When my obj_player its in a specific point of the map (x, y) , i tried place_meeting with an invisible object

You don't need place_meeting for that, you could just check if the coordinates match your destination. Just make sure to check for a range instead of exact coordinates, otherwise the condition will never be met.

Or, if you want to make something happen when the player is in a certain spot, you could just check if the coordinates of the player are inside of that object's sprite (even if invisible) .

How i could check this?

How do i check the coordinates?
Just like:
if (obj_player is on (x_y)) {
d3d_set_fog(true, c_black, 16, 128);
}

You need 4 variables to define a 2D-area:

• The left edge of the region
• The right edge of the region
• The top edge of the region
• The bottom edge of the region

Then you just use an if-statement using the comparative expressions available to you to ensure that the player's x coordinate is greater than the left edge and less than the right edge, and the player's y coordinate is greater than the top edge and less than the bottom edge.
