Hello, this is my first significant post I make in this forum!

As the title says, I'm unable to get drawing functions working while I call them by SCM or CLEO scripts. This occurs for every kind of functions which draw 2D or 3D primitives, so I'd point you to the CTexture__drawTexturedRect (0x728350) function as a reference.

I'd like someone who explain the reasons and (possibly) give me any solution.

Not sure I fully understand your problem. A view of your current script may help.

I've used that particular function in ASI but it doesn't sound like that exact function is what you are trying to call.

This should be the way to call that function.

SANNY

0AA6: call_method 0x728350 struct {*RwTexture} num_params 2 pop 0 {*dwRGBA} {*[X,Y,Width,Height]}

If not, then the parameter order needs reversing.

[Wesser]

Basically, I want to load a TXD dictionary differently from the "Script" one which is used by SCM. I've already made functions which enables me doing that but I cannot succeed on drawing those loaded textures. This is an example script:

SANNY

{$CLEO}

0000: NOP

while true
  wait 0
  0A8D: 0@ = read_memory 0xC403F4 size 4 virtual_protect 0 // _texShadExp
  0AB1: call_scm_func @drawTexture 9 texture 0@ cornerA_XY 160.0 120.0 cornerB_XY 480.0 1080.0 RGBA 128 128 128 255
end

:drawTexture
{
  Parameters:
    Passed:
      0@ - texture (offset)
      1@ - rect ul
      2@ - rect ll
      3@ - rect ur
      4@ - rect lr
      5@ - red
      6@ - green
      7@ - blue
      8@ - alpha
    Result:
      none

  Example:
    0AB1: call_scm_func @drawTexture 9 texture 0x0 cornerA_XY 0.0 0.0 cornerB_XY 0.0 0.0 RGBA 128 128 128 255
}
0A9F: 11@ = current_thread_pointer
0AB1: call_scm_func @getLocalVarOffset 2 thread 11@ var 1 store_to 9@
0AB1: call_scm_func @getRGBAValue 4 RGBA 5@ 6@ 7@ 8@ store_to 10@
0AA6: call_method 0x728350 struct 0@ num_params 2 pop 0 dwColor 10@ pRect 9@ // CTexture__drawTexturedRect
0AB2: ret 0

:getRGBAValue
{
  Parameters:
    Passed:
      0@ - red
      1@ - green
      2@ - blue
      3@ - alpha
    Result:
      4@ - color (offset)

  Example:
    0AB1: call_scm_func @getRGBAValue 4 RGBA 128 128 128 255 store_to 1@
}
0AA7: call_function 0x7170C0 num_params 4 pop 0 bAlpha 3@ bBlue 2@ bGreen 1@ bRed 0@ bResult 4@ // _RGBA__set
0AB2: ret 1 4@

:getLocalVarOffset
{
  Parameters:
    Passed:
      0@ - thread pointer
      1@ - var number
    Result:
      1@ - var value

  Example:
    0AB1: call_scm_func @getLocalVarOffset 2 thread 0@ var 0 store_to 1@
}
if
  0@ <> 0
then
  1@ *= 0x4
  0A8E: 2@ = 0@ + 0xDC // mission flag
  if
    2@ == 1
  then
    1@ += 0xA48960 // mission locals
  else
    005A: 1@ += 0@
    1@ += 0x3C
  end
else
  1@ = 0
end
0AB2: ret 1 1@

I don't know why the game doesn't show anything onscreen even if everything looks correct apparently.

[Deji]

Mmm.. That script crashes for me. This is doesn't crash but doesn't display the texture either:

SANNY

0@ = 0xFFFFFFFF
0AC7: 1@ = var 0@ offset
5@ = 10.0
6@ = 10.0
7@ = 40.0
8@ = 40.0
0AC7: 9@ = var 5@ offset
0AA6: call_method 0x728350 struct 0xBAB208 num_params 2 pop 0 dwColor 1@ pRect 9@

It works fine for me in an ASI, so it should be convertable...

CODE

RwRGBA colour = {0xFFu,0xFFu,0xFFu,0xB2u};
RwRect2D texturePos;
texturePos.x2 = _x(2.0);
texturePos.y2 = _y(346.0);
texturePos.x1 = _x(2.0 - 16.0);
texturePos.y1 = _y(346.0 + 24.0);
DrawTexturedRect(&HudTextures[0], &texturePos, &colour);

[Wesser]

Ok, thanks. So mine is more than just a suggestion. Every drawing function doesn't work in SCM/CLEO. I may try to use ASM code to call those functions instead of using the calling-function opcodes, otherwise I have to find a way to inject them by scripts.

I believe, I got the answer. Thanks again!

[Silent]

Yeah, ASM call should be a good way to do it, if CLEO call does not work

[DK22]

You guys made very big work on this!
I would wanna to know:
1) How to load txd using .asi (.dll) which made in cpp?
2) How to define textures (load_texture "" as)
3) Do I need to use smth like "enable_text_draw 1"
And I believe I could made it in __ASM in C++, but have just few questions:
1) How do you "attach" procedure in C++ to procedure in .exe?
2) How did you defined "HudTextures"? Is it an array of textures which must be loaded from models/txd? If yes, how did you "attached" it to array in .exe?
I really can't understand how these "pointers" work in C++...

[Wesser]

I'm sorry DK22, but we're talking about making texture showing by CLEO. You should open another topic to ask for ASI functions implementation.

Back on topic, I noticed game won't render anything in CGame__process() (0x53BEE0), but in CGame__Idle() (0x53E920) works! I injected an ASM function by overwriting a call to a NOP function:

CODE

{$CLEO}

0000: NOP

0AB1: call_scm_func @getLabelOffset 1 label @drawBarChart store_to 0@
0@ -= 0x53EBE9
0A8C: write_memory 0x53EBE4 size 1 value 0xE9 virtual_protect 1
0A8C: write_memory 0x53EBE5 size 4 value 0@ virtual_protect 1
0A93: end_custom_thread

:drawBarChart
hex
  68 00000000 // push 00000000h     dwRightBorderColor
  68 FF0000FF // push FF0000FFh     dwForeColor
  6A 01       // push 1             bBorder
  6A 00       // push 0             bPercentage
  68 00000000 // push 0             dwRightBorderWidth
  68 00004842 // push 50.0          fPercentage
  68 64000000 // push 100           dwHeight
  68 C8000000 // push 200           dwWidth
  68 00007043 // push 240.0         fPosY
  68 0000A043 // push 320.0         fPosX
  B8 40867200 // mov eax, 728640h   DrawBarChart
  FFD0        // call eax
  83C4 28     // add esp, 28h
  B8 E9EB5300 // mov eax, 53EBE9h
  FFE0        // jmp eax
end

Coordinates depend on the current screen resolution, so guess it is a test.

Windshield GUI 2.0 made via ASM?

[Wesser]

I hope so.

By the way, I made a better function than R*'s one, but I had some problems with screen scales. I may use the original routine which is hardly ever the worse choise.

OFFTOPIC: why the topic date says I've posted this message today (Today, 12:22 AM)? It's correct to say "Today, 0:22 AM". Is it a known bug?

DST confusion.

You have to scale your position and scale to SA resolution scale.

CODE

v4 = (long double)RsGlobal.MaximumHeight * 0.002232142956927419 * 22.0;
v5 = (long double)RsGlobal.MaximumWidth - 0.001562500023283064 * (long double)RsGlobal.MaximumWidth * 32.0;
_drawText(v5, v4, str);

IDA pseudocode helps a lot.

[Deji]

CGame::Process should run, assuming the function you're overwriting is not jumped past after a check. However, "_Render" does not run and it appears to be an unused function with debugging capabilities. But that's a different matter, I guess
