Lens Flare

[ZerbGames 55]

Technical Cover o' Topics

So first off this has probably been already suggested in which I apologize, but I know it has not yet been technically covered in how you would pull this off in gamemaker.  Also, I don't know what variables are set to but I'm sure they can be modified;) .
 
So you need to start off with 2 objects:
Camera (which has already been established)
&
Lens Flare (possibly this could be squeezed in with some other objects, but the overall effect wouldn't be the same)
 
Lens Flare (I will only be covering this)
Create Event:

global.rsunX = 0;
global.rsunY = -0.9;
global.rsunZ = 0.4;
global.angle = radtodeg(arctan(global.rsunZ/global.rsunY));
global.drawFlare = true;

Draw Event:

d3d_set_projection_ortho(0,0,640,480,0);
d3d_set_hidden(false);
if (global.drawFlare = true) {
d3d_convert_to_2d(objCamera.xf,objCamera.yf,objCamera.zf,
                  objCamera.xt,objCamera.yt,objCamera.zt,
                  0,0,1,45,640/480,
                  objCamera.xf+global.rsunX,objCamera.yf+global.rsunY,objCamera.zf+global.rsunZ);

a = 1-(point_distance(view_wview/2,view_hview/2,sunx,suny)/100);
draw_set_alpha(a);
draw_rectangle(0,0,641,481,false);
draw_set_alpha(1);
draw_set_blend_mode_ext(2,4);
draw_sprite_ext(sprSun,0,sunx,suny,2,2,0,c_white,a);
draw_set_blend_mode(bm_normal);

a = 1-(point_distance(view_wview/2,view_hview/2,sunx,suny)/500);

draw_flare(2,0.35,0.35,make_color_rgb(80,60,20));
draw_flare(1,0.39,0.1,make_color_rgb(60,50,20));
draw_flare(1,0.43,0.07,make_color_rgb(50,40,10));
draw_flare(2,0.65,0.1,make_color_rgb(40,30,100));
draw_flare(0,0.9,0.03,make_color_rgb(0,30,180));
draw_flare(2,1,0.35,make_color_rgb(80,60,20));
draw_flare(0,1.05,0.05,make_color_rgb(0,180,30));
draw_flare(1,1.65,0.7,make_color_rgb(30,20,10));
draw_flare(3,2,1.5,make_color_rgb(15,10,5));
}

d3d_set_hidden(true);

d3d_convert_to_2d script :

{
  //A very nice (and complicated) script made by Yourself
  var px,py,pz,dx,dy,dz,uX,uY,uZ,vX,vY,vZ,mm;

  dX = argument3-argument0;
  dY = argument4-argument1;
  dZ = argument5-argument2;
  mm = sqrt(dX*dX+dY*dY+dZ*dZ);
  dX /= mm;
  dY /= mm;
  dZ /= mm;

  uX = argument6;
  uY = argument7;
  uZ = argument8;
  mm = uX*dX+uY*dY+uZ*dZ;
  uX -= mm*dX;
  uY -= mm*dY;
  uZ -= mm*dZ;
  mm = sqrt(uX*uX+uY*uY+uZ*uZ);
  uX /= mm;
  uY /= mm;
  uZ /= mm;

  tFOV = tan(argument9*pi/360);
  uX *= tFOV;
  uY *= tFOV;
  uZ *= tFOV;

  vX = uY*dZ-dY*uZ;
  vY = uZ*dX-dZ*uX;
  vZ = uX*dY-dX*uY;
  vX *= argument10;
  vY *= argument10;
  vZ *= argument10;
  
  pX = argument11-argument0;
  pY = argument12-argument1;
  pZ = argument13-argument2;

  mm = pX*dX+pY*dY+pZ*dZ;
  if (mm > 0) {
     pX /= mm;
     pY /= mm;
     pZ /= mm;
  } else {sunx = -40000; suny = -40000; return 0; }

    mm = (pX*vX+pY*vY+pZ*vZ)/sqr(argument10*tFOV);
    sunx = (mm+1)/2*window_get_width();
    mm = (pX*uX+pY*uY+pZ*uZ)/sqr(tFOV);
    suny = (1-mm)/2*window_get_height();
}

draw_flare script:

rc = view_wview/2;
rm = view_hview/2;
k = argument1;
xx = sunx+(rc-sunx)*argument1; yy = suny+(rm-suny)*argument1;
draw_set_blend_mode(bm_add);
s = argument2*(50/(48+random(2)))
draw_sprite_ext(sprFlare,argument0,xx,yy,s,s,0,argument3,a);
draw_set_blend_mode(bm_normal);

This is what the final product should look like depending on what sprite you use.

o-o

 

 

 

Well, I've yet to see a suggestion shown like this.

 

I like.

Guude Guude... You have fallen for my trick!

I've used this concept in my ^*fake* Mine-imator 1.0.0 Full Super Duper Shuper Edition with Premium Minecraft topic, and seeing it inside the real Mine-imator would be epic.

 

 

I SUPPORT

Good good you have also, fallen for my TRICK!

[flufffybuns 926]

I don't understand but I would love to have lensflares

[Cryotivity 2.9k]

Sounds good although it could be easily done with a secondary editing software so idk if it would be added.

[ZZZZane 2.2k]

Welp. I'll wait for Davve's response. Also what do you mean by "trick"?

[Annie-Mienai 1k]

I think you should add an option for this.

Pfffffff..... Secondary!  This is the only software I will ever use!

Welp. I'll wait for Davve's response. Also what do you mean by "trick"?

You know the trick.  The one that I have done.
