dxbc_reader's Introduction

[feature]

FULL sm4.0 support(little sm5.0)
easy to use & easy to read

[usage]

.\lua\lua.exe dxbc_reader.lua example/fragment.txt -o dxbc.out

-o output [output filename]
-d true   [enable debug info]

translate DXBC code like:

dxbc_reader's Issues

Do you having some way to export DXBC code from GPA?

Your dxbc_reader tool is a awsome tool for reading code ! And do you having some way to export DXBC code from GPA? The save dxbc code button always disable when catching PC games.

how can i use it？

i don‘t understand should i open .\lua\lua.exe and then？

the Semantic Translate Error like the areas of red which below pic :

sincos

The sincos command seems to be converted incorrectly
sincos r1.x r2.x r3.x need to be r1.x = sin(r3.x); r2.x = cos(r3.x), but dxbc_reader result to r1.x = sin(r2.x); r1.x = cons(r3.x);

Not support abs() and centroid

Occured when have codes like:
dcl_input_ps linear centroid v1.xyz
and
lt r2.xyz, r3.xyzx, abs(r2.xyzx)
while i consider this a really convenient tool, hope someone can fix it ORZ

dxbc_parse.lua:235: attempt to perform arithmetic on a nil value (local 'idx_binding')

dxbc_reader fails on this dxbc code, the code is from gpa frame
gpa version is 2018R2，i have to use this version because only this version can attach on mumu(android 4) emulator。

Then output:


class $Globals{
        float4  _hlslcc_mtx4x4unity_ObjectToWorld;
        float4  _hlslcc_mtx4x4unity_MatrixVP;

But the sample code is working fine, and I am new to DXBC, what happened?

Do you having some way to export DXBC code from GPA?

.\dxbc_def.lua:106: attempt to index a nil value (local 'register')

how can i use it？

Semantic Translate Error

sincos

Not support abs() and centroid

dxbc_parse.lua:235: attempt to perform arithmetic on a nil value (local 'idx_binding')

I hope the god support sm5.0 as soon as possible

Not support abs() and centroid

Output the empty main function
