[REL] 50p's fun shaders

[50p]

Hi there people! I have been absent for long time and probably won't be as active as I used to be but I'll do my best. I just found out that MTA can load effect files and I wanted to learn how to write shaders. So far I have written only 1 very simple shader but I've learnt the basics how the whole process works (only pixel shading though) and should have some more.

Here is my very first shader:

- Horizontal flip - it flips your screen horizontally! Imagine that you know all 3 cities in SA. Will you know all the cities if the entire game was flipped horizontally? I bet it will take some time for you to know which turn to take to take you to the place where you want to go. I got lost multiple times when I wanted to get to Grove Street from 4 Dragons Casino.

good work and please buddy update the MTA Script Editor.

Nice , thats been awhile since I had not seen something funny like that. Mirror racing like in mario kart FTW

[Xierra]

Wow! Mirrored GTA World! Awesome!

I think some kind of mirrored route races are possible now.

50p, your first shader was one of the most interesting, things will get more confusing with this

Go and learn shaders more, then you'll be able to make cool shaders such as this one!

Thanks for the comments guys, I didn't know you'll like it. Anyway, a little update:

* added: flipped keys to make the driving easier (Mouse movement is not flipped though, can't think of the easiest way to do it. I don't want to make custom camera control to make it since this shader was made just for fun and shader writing practice)

dont see a mayor problem in lack of that

1)invert mouse

2)profit!

Invert keys if possible

nice, bud using shaders to flip the image is little overpowered

local w, h = guiGetScreenSize( ) 
screenSrc = dxCreateScreenSource( w, h ) 
addEventHandler( "onClientPreRender", root, function() 
   dxUpdateScreenSource( screenSrc ) 
   dxDrawImage( 0, w, -w, h,screenSrc ) 
end )

does it work?

i suppose it shouldnt.

[Wojak]

 screenSrc = dxCreateScreenSource( w, h ) 
 addEventHandler( "onClientPreRender", root, function() 
       dxUpdateScreenSource( screenSrc ) 
       dxDrawImage( w, 0, -w, h,screenSrc ) 
 end ) 

now it's ok, I've misplaced one "w"

(my rear view mirror script is a prove...)

[karlis]

oh i thought it just moved the bounds, not inverted the pixels, nice find!

[50p]

local w, h = guiGetScreenSize( ) 
 screenSrc = dxCreateScreenSource( w, h ) 
 addEventHandler( "onClientPreRender", root, function() 
       dxUpdateScreenSource( screenSrc ) 
       dxDrawImage( w, 0, -w, h,screenSrc ) 
 end ) 

now it's ok, I've misplaced one "w"

(my rear view mirror script is a prove...)

Doesn't that flip HUD as well?

it is PRErender

btw if pre doesnt work, use onClientHUDRender, it is triggered be4 hud is drawn.

[Wojak]

its impossible to capture hud components and dx elements into screen source, so when you use prerender they are drawn on top

inverted canera can be done using freecam. great stuff 50p

[Spanish4Life]

Hey, more shaders? It's good but you can do anything more

[Faw[Ful]]

If you want more , make your own !

[Spanish4Life]

but if "shaders" do one more atleast >_> or change it, it sounds like a liar Edited November 11, 2011 by Guest

[12p]

Yea, it sounds like a lie

[50p]

LOL

OK, I'll write a black&white shader and use it when you die, you know, like in GTA IV. In fact, I did write such shader but I lost it due to C:\ format

[karlis]

also add the zoomout and camera roll effect to it(not really a shader)

If I was to make such resource I would add it but it's just a shader and you can add it yourself I might add it in the future but first I have to fix MTASE to work with MTA SA 1.1
