RwD3D9DDSTextureRead – Alpha?

[DK22Pac]

You can use CSprite2d::Draw method with additional texture coordinates setup:

void Draw(CRect  const& posn, CRGBA  const& color, float u1, float v1, float u2, float v2, float u3, float v3, float u4, float v4);

where
u1, v1 - texture coordinates for left-top corner vertex
u2, v2 - texture coordinates for right-top corner vertex
u3, v3 - texture coordinates for left-bottom corner vertex
u4, v4 - texture coordinates for right-bottom corner vertex

#include "plugin.h"
#include "game_sa\CSprite2d.h"
#include "game_sa\CScene.h"

using namespace plugin;

class TextureTest {
public:
    TextureTest() {
        static CSprite2d sprite;

        Events::drawingEvent += [] {
            if (!sprite.m_pTexture)
                sprite.m_pTexture = RwD3D9DDSTextureRead(PLUGIN_PATH("logo"), NULL);
            sprite.Draw(CRect(SCREEN_COORD(100.0f), SCREEN_COORD(100.0f), SCREEN_COORD(800.0f), SCREEN_COORD(800.0f)),
                CRGBA(255, 255, 255, 255), 0.1f, 0.1f, 0.7f, 0.1f, 0.1f, 0.7f, 0.7f, 0.7f);
        };

        Events::shutdownRwEvent += [] {
            sprite.Delete();
        };
    }
} test;

You can also create your own function where these parameters will look much more understandable.

#include "plugin.h"
#include "game_sa\CSprite2d.h"
#include "game_sa\CScene.h"

using namespace plugin;

class TextureTest {
public:
    static void DrawSpritePart(CSprite2d &sprite, float x, float y, float w, float h, CRect const &part) {
        sprite.Draw(CRect(x, y, x + w, y + h), CRGBA(255, 255, 255, 255),
            part.left, part.top, part.right, part.top, part.left, part.bottom, part.right, part.bottom);
    }

    TextureTest() {
        static CSprite2d sprite;

        Events::drawingEvent += [] {
            if (!sprite.m_pTexture)
                sprite.m_pTexture = RwD3D9DDSTextureRead(PLUGIN_PATH("logo"), NULL);

            float size = SCREEN_COORD(280.0f);
            DrawSpritePart(sprite, SCREEN_COORD_CENTER_LEFT(300.0f), SCREEN_COORD_CENTER_UP(300.0f), size, size, CRect(0.0f, 0.0f, 0.5f, 0.5f));
            DrawSpritePart(sprite, SCREEN_COORD_CENTER_RIGHT(20.0f), SCREEN_COORD_CENTER_UP(300.0f), size, size, CRect(0.5f, 0.0f, 1.0f, 0.5f));
            DrawSpritePart(sprite, SCREEN_COORD_CENTER_LEFT(300.0f), SCREEN_COORD_CENTER_DOWN(20.0f), size, size, CRect(0.0f, 0.5f, 0.5f, 1.0f));
            DrawSpritePart(sprite, SCREEN_COORD_CENTER_RIGHT(20.0f), SCREEN_COORD_CENTER_DOWN(20.0f), size, size, CRect(0.5f, 0.5f, 1.0f, 1.0f));
        };

        Events::shutdownRwEvent += [] {
            sprite.Delete();
        };
    }
} test;

Yes, it's a problem with that plugin you used to generate .dds.
If you have DirectX 9 SDK installed, you can use DxTex utility (it's in Utilities\bin\x64/x86 folder) to re-save your texture.
Or you can use NVidia's DDS plugin for Photoshop, I have never had problems with it.
logo.zip

Also, some fix to your code: do not use class name to name an instance of you class (variable). Use, for example, tacticRadar.

class TacticRadar {
    // ...
} tacticRadar; // use different name here

[quiret]

No problem! Glad to help you. Here is the code of FindPlayerHeading.

As you can see, you MUST NOT pass -1, but you have to pass 0.

Would be glad to see if the R* methods of getting heading actually work for you :-)

[DK22Pac]

For map markers, you need to go with ms_RadarTrace array.
Something like this:

for (int i = 0; i < MAX_RADAR_TRACES; i++) {
    auto &blip = CRadar::ms_RadarTrace[i];
    // check if blip exists
    if (blip.m_bTrackingBlip) {
        // perform any other actions - for example, check sprite id
        if (blip.m_nBlipSprite == RADAR_SPRITE_POLICE) {
            // ...
        }
    }
}

For sprite transparency, you can setup it in "color" parameter:
sprite.Draw(CRect(left, top, right, bottom), CRGBA(red, green, blue, alpha));

I'm closing this issue now. If you have any other questions, please create a new one with a proper name.

[DK22Pac]

Hello and welcome to plugin-sdk community.
RwD3D9DDSTextureRead does not use second parameter (called "maskName"), so you can set this parameter to NULL.

1. Are you sure your .dds file uses alpha channel? Can you upload it so we could check?
2. How do you draw your texture? Maybe you missing something in the 'drawing' part?

[edgarpochtel]

Hi!

Thank you for your answer.
I thought the second parameter is properly for masking.

Yes, my .dds file has an alpha channel, i used the following plugin to create my .dds file:
http://gametechdev.github.io/Intel-Texture-Works-Plugin/

Link to .dds file: https://www.file-upload.net/download-12596036/logo.dds.html

I used your example to draw textures.
Source:

#include "plugin.h"
#include "game_sa\CSprite2d.h"

using namespace plugin;

class TacticRadar {
public:
    TacticRadar() {
        static CSprite2d sprite;

        Events::drawingEvent += [] {
            if (!sprite.m_pTexture) // load texture only once
                sprite.m_pTexture = RwD3D9DDSTextureRead(PLUGIN_PATH("logo"), PLUGIN_PATH("logo_alpha")); // rw api gives you ability to load dds images
            sprite.Draw(CRect(10.0f, 10.0f, 300.0f, 300.0f), CRGBA(255, 255, 255, 255)); // draw sprite
            
        };

        Events::shutdownRwEvent += [] {
            sprite.Delete(); // delete loaded texture
        };
    }
} TacticRadar;

It doesn't work with the given .dds file, but with a .dds file, without alpha channel, it works.

Greetings

[edgarpochtel]

Thank you very much!

It works fine, i tried the NVidia DDS Plugin, and it works.
Also thank you for the advice relating to the instance name.

One last question:
Is there any chance to show only a specific part of the image? Like cropping the image?
For better understanding: I want to create an image (compas, like in Player Unknows Battlegrounds)
and show only the needed part of the image.

Thank's for your help!

[edgarpochtel]

That's awesome! Thank you.

I create the modification and will inform you with the result!

See ya.

[edgarpochtel]

Hi. Again a question. How do I use SCREEN_COORD properly?
The resolution of my image is 1064x40.

That's acutally what I have:

float width = SCREEN_COORD(500.0f);
float height = SCREEN_COORD(40.0f);

And it looks not that bad, but also not right.

[DK22Pac]

Maybe

float width = SCREEN_COORD(532.0f); // 1064 / 2
float height = SCREEN_COORD(20.0f); // 40 / 2

?

[edgarpochtel]

Oh. Sorry, I totally forgot to say, that I figured it out.

But I have another problem:

Events::gameProcessEvent += UpdatePlayerCoords;

static void UpdatePlayerCoords() {
		KeyCheck::Update();

		if (KeyCheck::Check(VK_SHIFT)) {
			if (KeyCheck::CheckJustDown('1')) {
		                  CMessages::AddMessage("Hi", 3000, 0, false); // Does not work
			}
		}
	}

Is it becuase I play/test it on SAMP?

Acutally, it does not work either with other functions.

[DK22Pac]

What if you will just output an error message?

Events::gameProcessEvent += [] {
    Error("gameProcessEvent");
};

[edgarpochtel]

Doesn't show up anything, tried with my code and with your example above.

But the images created under Events::drawingEvent showing up.

Edit:

Under Events::drawingEvent the function Error shows up a MsgBox.

[DK22Pac]

Okay... Looks like a conflict with SAMP.
You can try processScriptsEvent as a replacement for gameProcessEvent.

[edgarpochtel]

Ok, that's helpfuel, thank you.

How do I get the Rotation of the player? player->m_fCurrentRotation and player->m_fCurrentRotation
returning a too small number. If north is 0 and 360 (like SAMP? doesn't know aktually).

And is there also an option to get the rotation/direction of the player camera?

You are very kind and helpfuel, I thank you for the help!

[kateon11]

They're probably in radians.

[edgarpochtel]

Okay, thank you. I will see if that could be.

[edgarpochtel]

Hello.
i was on vacation, sorry for the late reply. I converted radian to degree, but it looks wrong.
Mostly I get a negative response. Maybe @DK22Pac can answer my question?

[DK22Pac]

Try FindPlayerHeading

[edgarpochtel]

Hi.
FindPlayerHeading doesn't return anything, and it causes to stop my mod.
player->m_fCurrentRotation returns the player angle in radians, so that's not the problem.

I actually get it. Doesn't know, what I did wrong. THere is maybe a better solution, but this works for me:

static float ConvertRadiansToDegree(float radian) {
	static float radianConv = 57.295779513082F;
	float response = 0.0F;
	if (radian < 0) {
		response = 180.0F;
		radian = radian + 3.14159F;
	}
	response = response + (radian * radianConv);
	return response;
}

[edgarpochtel]

Hi again.

Soon I'll be ready. But I need to calculate the position of the image with the roation. <- No problem for me.

But there is still my question about the camera direction. Is there any function to get the camera direction?
With the camera direction the mod looks a lot better. Here is a preview:

https://www.youtube.com/watch?v=4L20EBYy8Ww

[quiret]

@Cireyses
and it causes to stop my mod.

Hopefully you passed 0 for first player as argument and are trying to get rotation of a player that was created by the game ;-)

To get the camera direction I recommend using the CCamera::GetHeading method that is available because the CCamera class is also a CPlaceable.

[edgarpochtel]

Hi @quiret!

Yes, I passed -1 for the player not 0, like the other functions.
Yesterday I found the CCamera file and tested TheCamera.m_fOrientation,
and it works properly. I will see, if I get a same result with your method.

Thank you.

[edgarpochtel]

Works fine so far.
Is there any possibility to get all map markers on the map?
Like a list with ht eicon name or something else.
I want to show the map icons also in the compass.

And: Can I set a transparency to a sprite/draw, separately from the transparency of the image?
