The gex was programmed and tested on a Netbook, so performance is optimized at best, to work in any device.

Thanks to jak for rendering method with 2 blend modes and backface culling formula.

O MY GOD ! very nice man! the best light engine ever!

-30/30 fps with a lot of light and meshes!
FANTASTIC

Very neat!
I've a question though: Is your example compiled in Game Maker Studio? o: Because it works a lot faster than when I'm compiling it myself in GM 8.1

I believe he used GM 8.0

[Drara]

I use GM 8.0

Oh o: Can it really be that GM 8.1 is slower than 8.0? o-o

[Pancratius]

I'm sorry, maybe its because I'm new to game maker coding, but I had a look at the coding in your example, and couldn't get my head around it at all. Would it be possible for you to comment it please. It would make it much easier to understand.

I'm preparing some tutorials

SEE at OPENPOST

If you also want to post some examples, or if you create some games using this gex
Send me a PM! I will provide to include them in the OpenPost

That tutorial is quite helpful, but doesn't seem to work. It gives an error when I right click the lights to remove them.

This is the error:

___________________________________________
ERROR in
action number 1
of Destroy Event
for object obj_light:

Error in code at line 2:
   tl_light_delete(l);
                   ^
at position 18: Unknown variable l

To fix this I created a variable using the D&D method called my_light, before the code in the create event of the obj_light. I then changed the line causing the problem to:

tl_light_delete(my_light);

and this problem did not occur again.

Also, I am working on a game which is using this extension. However I am attempting to make the game at a resolution larger than 640x480. The problem is the ambient lighting does not extend to the size of the room. Here is an image which illustrates what I mean:

How might I extend the ambient lighting to the extents of the room?

[tizzio]

Thank you, for testing

The light follows the size of the view.
So set the view, equal to the size of the window!

in Room editor
-> room width : 900
-> room height: 700

-> view wport : 900
-> view hport : 700

view sizes must be smaller (or equal) than room width !

Working perfectly now thanks for your help .

[CrazyGuyGames]

Amaizing, just what I need, but I don't understeand it, can you comment it or make another example, but more simple?

[thatonenerd22]

Well, now I feel silly for wasting 3+ months and multiple versions making a not-quite-as-good lighting engine.

global.viewx = round(view_xview/gridsize)*gridsize
global.viewy = round(view_yview/gridsize)*gridsize
r = 0
g = 0 
b = 0
strength = 0
xx = global.viewx-gridsize*2
yy = global.viewy-gridsize*2
reps = 0
draw_set_color(c_white)
lines = 0
repeat((view_wview/gridsize+2)*(view_hview/gridsize+2)+view_wview)
{
with(light_parent)
{
i = collision_line(x,y,controller.xx,controller.yy,obj_solid,true,true)
if i <1
{
if (point_direction(x,y,controller.xx,controller.yy) <= maxdir and point_direction(x,y,controller.xx,controller.yy) >= mindir)
or (point_direction(x,y,controller.xx,controller.yy)-360 <= maxdir and point_direction(x,y,controller.xx,controller.yy)-360 >= mindir)
or (point_direction(x,y,controller.xx,controller.yy)+360 <= maxdir and point_direction(x,y,controller.xx,controller.yy)+360 >= mindir)
{if
point_distance(x,y,controller.xx,controller.yy) < strength
{if (x > global.viewx-strength and y > global.viewy-strength and x < global.viewx+view_wview+strength and y < global.viewy+view_hview+strength)

{
controller.strength = max(0,min(1,controller.strength,(point_distance(x,y,controller.xx,controller.yy)/strength)*intensity))
controller.r = max(controller.r,r*(1-point_distance(x,y,controller.xx,controller.yy)/strength)*cintensity)
controller.g = max(controller.g,g*(1-point_distance(x,y,controller.xx,controller.yy)/strength)*cintensity)
controller.b = max(controller.b,b*(1-point_distance(x,y,controller.xx,controller.yy)/strength)*cintensity)
controller.lines+=1
}}}}



}
draw_sprite_ext(spr_shadow,0,xx,yy,
gridsize/8,gridsize/8,0,
make_color_rgb(r,g,b),strength)
 
//draw_sprite_ext(spr_shadow,0,xx,yy,gridsize,gridsize,0,c_black,strength)
xx += gridsize
if !(xx < global.viewx+view_wview+gridsize*2)
{xx = global.viewx-gridsize*2
yy += gridsize}

r = 10*global.sunlight
g = 10*global.sunlight
b = 0
strength = global.sunlight
}

Come on, do not demoralize!
I started this light engine 4-5 months ago, but I use game maker for the past 2 ½ years.
I am sure that you will be able to do better than me

[Pancratius]

Hello.

I have been trying to use this extension now for a few days, and I think I'm getting the hang of it. However I am lagging really badly when using multiple lights in my own work. However when I used your example, there were no issues. I am hoping you can help me with this. Here is a link to my GMK file.

http://www.mediafire...da90hqrrg56mbdf

Could you please point me towards where my problem could be.

Kind Regards,
Pancratius

[tizzio]

ok i try and tell you

[tizzio]

The problem is that you used 300000000000 mesh
1 mesh for each piece of wall
Use a single mesh for long pieces of wall, it will go much faster!

[JeroenV]

I have a problem that's mainly my faul, I just need to find how to fix it. I have a random generation code for my game wich is quite extensive, I recently wanted to try and add your lighting engine to improve the looks of the game. I'm just using all the standard codes from the example but because of my generation code (I believe) it does not work properly.

I created a "Light" room, with the obj_engine and then let it move on to the next room. Yet if I use room_next it will just skip the next room and if I use room_goto("Roomname") it's just a black screen.

And I believe it might be because of this code.

var o;
global.loaddone=0
o=random(100)
{

for(i=0;i<100;i+=1){
a=random(room_width)
b=random(room_height)
position_destroy(a,b) 
instance_create(a,b,obj_tree)
}



for(i=0;i<100;i+=1){
a=random(room_width)
b=random(room_height)
position_destroy(a,b) 
instance_create(a,b,obj_tree1)
}



for(i=0;i<100;i+=1){
a=random(room_width)
b=random(room_height)
position_destroy(a,b) 
instance_create(a,b,obj_tree2)
}


for(i=0;i<1;i+=1){
a=random(room_width)
b=random(room_height)
position_destroy(a,b) 
instance_create(a,b,obj_seasource)
}

for(i=0;i<5;i+=1){
a=random(room_width)
b=random(room_height)
position_destroy(a,b) 
instance_create(a,b,obj_forestsource)
}

for(i=0;i<30;i+=1){
a=random(room_width)
b=random(room_height)
instance_create(a,b,obj_stone)
}



if(o=1)
{
a=random(room_width)
b=random(room_height)
position_destroy(a,b) 
instance_create(a,b,obj_oceansource)
}

for(i=0;i<10;i+=1){
a=random(room_width)
b=random(room_height)
position_destroy(a,b) 
instance_create(a,b,obj_water)
}


}
timeline_running=true

Now, as you can see this code deletes everything beneath it to make sure there isn't more than 1 instance on the same spot. The obj_light is created after the world has generated using a 'loading' timeline. So why is my screen black, entirely?

It's quite a big project I'm working on I would love if this could work with my current setup.

Thanks.

[tizzio]

Hi, JeroenV!
Check that you have initialized the object "engine" light in the room and set this as "Persistent".
If you make a .gmk without your code, it works?

If you want, send me a Private message with an example.
I'll try to help you!
