its simple sigth drawing. very useful but not very fast when you decrease distance between points.

draw_sight(x,y,sight view,angle, distance between points,sight range,color,outline width,alpha)

for(i=0 i<argument2 i+=argument4)
{var uzaklik,uzaklik2;
uzaklik=0
uzaklik2=0
do{uzaklik+=2    }
until(collision_line(x,y,x+lengthdir_x(uzaklik,i-argument2/2+argument3),y+lengthdir_y(uzaklik,i-argument2/2+argument3),argument6,1,0) or uzaklik>argument5)
do{uzaklik2+=2    }
until(collision_line(x,y,x+lengthdir_x(uzaklik2,i-(argument2/2-argument4)+argument3),y+lengthdir_y(uzaklik2,i-(argument2/2-argument4)+argument3),argument6,1,0) or uzaklik2>argument5)

draw_line_width_color(x+lengthdir_x(min(argument5,uzaklik-3),i-argument2/2+argument3),y+lengthdir_y(min(argument5,uzaklik-3),i-argument2/2+argument3),x+lengthdir_x(min(argument5,uzaklik2-3),i-(argument2/2-argument4)+argument3),y+lengthdir_y(min(argument5,uzaklik2-3),i-(argument2/2-argument4)+argument3),argument8,argument7,argument7)
draw_set_alpha(argument9)
draw_triangle_color(x,y,x+lengthdir_x(min(argument5,uzaklik),i-argument2/2+argument3),y+lengthdir_y(min(argument5,uzaklik),i-argument2/2+argument3),x+lengthdir_x(min(argument5,uzaklik2),i-(argument2/2-argument4)+argument3),y+lengthdir_y(min(argument5,uzaklik2),i-(argument2/2-argument4)+argument3),argument7,argument7,argument7,0)
 draw_set_alpha(1)
if i=0 
{draw_line_width_color(x,y,x+lengthdir_x(uzaklik-3,-argument2/2+argument3),y+lengthdir_y(uzaklik-3,-argument2/2+argument3),argument8,argument7,argument7)
}
if i=argument2-argument4
{
draw_line_width_color(x,y,x+lengthdir_x(uzaklik2-3,+argument2/2+argument3),y+lengthdir_y(uzaklik2-3,+argument2/2+argument3),argument8,argument7,argument7) }
}

example
draw_sight(x,y,80,direction,5,150,obj_wall,c_red,0,0.8)

Wow, this looks awesome! This is a really wonderful engine that you have made - combined with collision_line() and point_distance(), you could create some awesome AI. I hope to see some games with this in it. (Maybe from me, even) Thank you taking the time to make this.

Oh, my God. This seems to be pretty good.
Only, Speed ​​only a little bad.

this is pretty cool but it runs really slow

[iam1me]

I think you could get this to run faster if you started off by drawing the entire range (on to a surface) and then grab all of the instances in the area and subtract their "shadows." You could have a fast version that runs off of the bounding boxes and a slower one that is pixel precise.

Cool idea though
