Yeah, you can do it by using variables. First, you need to record the x and the y possitions of the hero and the gaurds or whatever are going to have the line of site.

Do this by...

Go to variable options
Select a variable to save the value to. (name it gaurd x or gaurd y)
Click on the sprite option
select the sprite you want
select either x coordinate or y coordinate.
After saving an x value, make a new variable, and save the y variable to it.
Repeate for all gaurds and the hero.

Now for all the gaurds, record which dirrection their facing.
Again, this is done in variable options and then the sprite option.


All of these variable options should be put in a parallel proces event with a .1 wait command.


Now you need another parallel process event with a wait of .1 or .0. In this event, you need a bunch of conditional branches to test where the hero is compared to to the gaurd and where the gaurd is facing. Sadly, this will require a lot of conditional branches.

First, for each gaurd, make a conditional branch for the four dirrections they can be facing. In each of those branches, test to see if the hero's x possition is within 10 tiles of the gaurd in whatever dirrection the gaurd is facing. So if the gaurd is facing up, check to see if the hero's y possition is between the gaurds y and 10 less than the guards y. In that branch, do you actions.

For every dirrection, you'll need a differant formula, for up and down, check the y possiitons, if facing left or right, check the x formulas.

*sigh* gamingw and their quick responces. Well either way, I'm glad you were able to get an answer. The better people get at rpg maker, the better games they make, and the better the rpg maker community gets
