Game Atmosphere Effects

[Goliath]

Hello there!

I´m trying to create diferent atmospheres in OpenBor like fog or rain effects. I achieve to create a realistic Fog Effect but would like to hear from people also interested on this what are his methods or how they do weather or atmosphere changes on games.

I´l explain my fog method:

It consist on two panels a and b, both uses alpha 6 (50% opacity):

Panel a moves right and up at defined velocity, when reaches certain altitude inverses direction and speed, and again when reaches certain altitud inverses to first movement creating a loop.

Panel b does the same as panel a but the opposite starts moving left and up, and reached certain altitud inverses velocity and direcction.

Result:

Feel free to post your own methods!

Nice effect. I think you could use drawmethod to simulate the "water effect" (raster effect), the result would be cool.

 

[erf_beto]

that's cool effect!
Have you tried looping the left and right panels at a different rate, so it looks less symmetric?

How you do that?
I see there is watermode property on drawmethod but don´t know how to activate it.

No, but I´ll try it.

masterderico has implemented couple game atmosphere effects in his Jennifer mod. you can immediately feel dark atmosphere when playing that mod

My eyes hurt a bit when entering bright (normal) stage though

Use this in animation and change wavetime on each frame

@cmd changedrawmethod getlocalvar("self") "reset" 1
	@cmd changedrawmethod getlocalvar("self") "enabled" 1
	@cmd changedrawmethod getlocalvar("self") "watermode" 2
	@cmd changedrawmethod getlocalvar("self") "amplitude" 5
	@cmd changedrawmethod getlocalvar("self") "wavespeed" 1
	@cmd changedrawmethod getlocalvar("self") "wavelength" 25
	@cmd changedrawmethod getlocalvar("self") "wavetime" 0
	frame data/chars/misc/flamedrg.png
	@cmd changedrawmethod getlocalvar("self") "wavetime" 10
	frame data/chars/misc/flamedrg.png
	@cmd changedrawmethod getlocalvar("self") "wavetime" 20

Great!
Thanks!

Use this in animation and change wavetime on each frame

Or...use the effect with a SIN to make it smoother

How is that?

About create fog: Continuous here, I started consulting in the thread "Sinusoid Motion via Script".
http://www.chronocrash.com/forum/index.php?topic=1900.msg28968;topicseen#new

i create a entity type none, and move slow this entity to the right,  this look great.
But the problem is the fog soon or later goes out of the screen.

Bloodbane says:

Well, spawn another one then . You can use infinite spawner to spawn fog again if one has moved far enough.

How I can do this?

 

[Bloodbane]

Just like this:

name         FogSpawner
speed         10
type         panel
load          Fog

anim idle
loop 1
delay 1
offset 1 1
        spawnframe 1 400 200 0 1
        custentity Fog
frame data/chars/misc/empty.gif
delay 300
frame data/chars/misc/empty.gif

This FogSpawner will spawn Fog 400 pixels to the right at z = 200 every 3 seconds
You can modify spawnframe parameters and delay value to suit your need

Thanks my friend!

About this:

You need to use bgspeed to do that and set relative speed in fglayer command (last parameter). To 'prevent' background from moving, make a clone of background with bglayer

Can you give me a example of the level with every sets, to understand better how do it?

 

[Bloodbane]

Here's and example from D&D mod we're working on:

background data/bgs/town3/deserted.gif
panel data/bgs/town3/deserted.gif
fglayer data/bgs/town3/fg.gif 10 0 0 0 0 0 0 -1 1 1
fglayer data/bgs/swamp/mist.png 20 0 0 0 -60 0 0 -1 1 1 1 0 0 0 0 -0.7
fglayer data/bgs/swamp/mist2.png 22 0 0 0 -40 0 0 -1 1 1 1 0 0 0 0 -1.05
fglayer data/bgs/swamp/mist.png 24 0 0 0 40 0 0 -1 1 1 1 0 0 0 0 -1.4
order         a
bgspeed 1

In this example, panel graphic is big enough to cover the screen so bglayer isn't needed. Since background is covered by panel, you can set bgspeed without 'moving' the panel
All last 3 fglayers have last parameter set which defines how fast they 'move' in relative to bgspeed

Works great!
Thanks my friend.
I have to learn a lot about stages,  because always work only in the characters.
