Anyone done a Night Vision Goggle effect ?

#1 Post by Roxus » Wed Sep 23, 2020 4:21 pm

I'd like to replicate the XP11 Night Vision effect on AM and was wondering if its already been done ?

I'm thinking something like a transparent panel over top of the existing one with a fullscreen "green image" that I will vary the opacity on, randomly ?
I think also I might either rotate the image 180deg every 10ms to get the effect of the speckles moving, or change the visibility on a few similar images in order to get that effect ?

But any input or ideas, would be appreciated

Hi, we are very close to that.
Just some fun, but it suggests many possibility. I would like to see others expand on this.

@Ralph @Sling and my dear friend @JackZ. Jacques You started this Disco trend. :lol:

Code: Select all

color_palate_canvas= canvas_add(0,0,500,500)
--Create a Hex Table to provide (33x33x33) color palate 
ht={"ff","f8","f0","e8","e0","d8","d0","c8","c0","b8","b0","a8","a0","98","90","88","80","78","70","68","60","58","50","48","40","38","30","28","20","18","10","08","00"}

i3=1
a=1
function disco(count)	
	i3=i3+a
	i3 = var_cap(i3,1,33)

	canvas_draw(color_palate_canvas, function()		
		for i1=1,33 do	
			for i2 = 1,33 do														
				_rect(65+(i1*10),65+(i2*10),10,10)		
				_fill("#"..ht[i1]..ht[i2]..ht[i3])					
			end				
		end				
	end)
	if i3 == 33 then a = -1 end
	if i3 == 1 then a = 1 end	
rotate(	color_palate_canvas, 0, "LOG", 0.05)
rotate(	color_palate_canvas,25*i3)
end
timer_start(0,200,disco)

I'm not sure if just a green overlay would work. It probably also has effect on light and shadows.

Ralph,

I am up for the challenge. I will draw a round bezel with color gradients using about 30 lines of code. I am sure guys like @Sling (yes I am challenging you Tony), could probably do it in fewer lines and before I wake up tomorrow morning. :mrgreen:

Keith

EDIT: I did a bit of experimenting with adding some extra code to try and get the feel for Night vision. The four corners show white, black. red and blue.
The overlay is a few shades of night vision green. You might want to add more or change those colors.
The opacity changes every 30 seconds so the whole cycle takes about 5 minutes. You should see the print statements indicate what color and what opacity is done.
Hope it helps.

Code: Select all

base_canvas = canvas_add(0,0,500,500, function()
	_rect(0,0,500,500)
	_fill("#37474f")
	_rect(20,20,50,50)
	_fill("white")
	_rect(430,20,50,50)
	_fill("black") 
	_rect(20,430,50,50)
	_fill("red")
	_rect(430,430,50,50)
	_fill("blue")  
end)
color_palate_canvas= canvas_add(0,0,500,500)

No interest in simulating NVG from my side, sorry.
