Beta 26 shader syntax error

vvvv beta question
#1

hi and big thanks to the devvvvs for this promising release

for now it looks to work great except a little problem i have with an effect (Desax’s SurfacesPhongDirectional.fx) returning “nil” on technique pin.

as advised in the release page i checked the code and yes it looks to be a syntax problem (“line 5832 - redefinition of SteinbachScrew”) but i don’t know how to resolve this as i’m not an hlsl friend.

shader is here tiki-download_file.php?fileId=1193

any help appreciated…

Help getting Echo8.fx node working
#2

same for distortions 2d shader. Line 333 redefinition of fisheye.

Distortions_2D.fx (8.8 kB)

#3

This compiler change should have been done a long time ago - finally it might force ppl to write shaders correctly =)
As for fixing it - you could try to hexedit the executable and replace the string “d3dx9_XX.dll” by “d3dx9_30.dll”(or whatever it was in previous versions), but please do that only if you really have no time and no other options. And i’m not even 100% sure will this trick work or not…

#4

Aie… Unc would you please have a look at distorsion2d ? Despite it is bad written it is very usefull!!!

#5

…a lot of shaders are returning nil due to smple syntax errors.

Interesting but what has exactly changed here?

#6

Yes, can someone elaborate on how to fix these errors?

#7

the fix is quite easy! most of the time the technique is called like a function of the shader, so just rename this function. i would not rename the technique, because that would break patches using the technique name enum.

#8

Can someone post an example? :)

#9

if you have a function

float3 SteinbachScrew(…)

and a technique

technique SteinbachScrew
{
…
}

rename the function to

float3 SteinbachScrewFunc(…)

or so…

#10

ahh ok.

Just make sure no function shares a name with a technique?..

#11

right, no structure should have the same name than another… the compiler is more strict in naming checks now.

#12

also, make sure shader model 1 is not mentioned (change to 2_0 atleast)
and i remember someone’s shader with “writing” to a global variable - this shouldnt happen

#13

now it got the func! (and 2.0)

thanks a lot guys and big up unc for your amazing texture effects!

#14

here’s Distortions2d in case but i just added func and 2.0. nothing uncroyable…

#15

why isn t it possible ?

@users: contribs would appreciate this shampoo of Func thing ?

#16

this isnt really a good style, and i believe this ‘writing’ was restricted by the compiler (options)
