How do i draw sprites?

M8T

Was trying to load this in Function.Call(Hash.DRAW_SPRITE, "heisthud", "main_gradient", 0.5f, 0.5f, 0.5f, 0.5f, 0.0f, 255, 255, 255, 1);
Nothing happens when loading it though, what do i do?

@M8T Let me know when you find out, not easy it seems. You will need to put it ontick AFAIK.

@JohnFromGWN I have put it on tick

@M8T try this

using System;
using System.Drawing;

using GTA;
using GTA.Math;
using GTA.Native;

namespace SimpleSpriteDrawTest
{
public class cSimpleSpriteDrawTest : Script
{
const string SpriteLibrary = "mySprites";
const string SpriteName = "mySpriteTexture";

>    public cSimpleSpriteDrawTest()
    {
        Tick += onTick;
        Interval = 0;
    }

    private void onTick(object sender, EventArgs e)
    {
        // Exits from the loop if the game is loading
        if (Game.IsLoading) return;

        DrawSprite();
    }

    private void DrawSprite()
    {
        // Centre of the screen
        float spriteX = .5f;
        float spriteY = .5f;

        // Get the texture resolution, textureRes.X = width, textureRes.Y = height
        Vector3 textureRes = Function.Call<Vector3>(Hash.GET_TEXTURE_RESOLUTION, SpriteLibrary, SpriteName);

        // Divide those values by the screen resolution to get the required scale values to draw it at normal size.
        // NOTE: The scale values are a percentage of the SCREEN size, not the SPRITE size... 1f = Draw the sprite the size of the screen
        float scaleX = textureRes.X / Game.ScreenResolution.Width;
        float scaleY = textureRes.Y / Game.ScreenResolution.Height;

        // Set the rotation to 0
        float rotation = 0f;

        // Set the colour to white
        Color col = Color.White;

        // Has the texture library loaded?
        if (Function.Call<bool>(Hash.HAS_STREAMED_TEXTURE_DICT_LOADED, SpriteLibrary))
        {
            // If Yes, draw the sprite
            Function.Call(Hash.DRAW_SPRITE, SpriteLibrary, SpriteName, spriteX, spriteY, scaleX, scaleY, rotation, col.R, col.G, col.B, col.A);
        }
        else
        {
            // If No, request it
            Function.Call(Hash.REQUEST_STREAMED_TEXTURE_DICT, SpriteLibrary, false);
        }
    }
}

}

@JohnFromGWN Thanks that spawned the texture but im having an issue, is there a way to change the transparency?

JohnFromGWN

@M8T research the function. Can you edit the texture and does it even support transparency

M8T

@JohnFromGWN nvm i dont need the transparency any more. Anyways thanks!

JohnFromGWN

@M8T I'm assuming a transparent png would work? For a dds file, you need to play with the alpha channel in image editor (Photoshop) I think. Never tried.

Anyway, I tried the code myself and it does work. However I'm using SHVDN3, not DN2, so one function had to be changed.

GTA.UI.Screen.Resolution.Width; insted of Game.ScreenResolution.Width;

same for the height of course

Just curious, if you are using a custom sprite, did you create a new YTD file as a library or did you add your sprite to an existing library?

JohnFromGWN

@M8T If you ever do need transparency, i just tried it with a transparent png and let OpenIV convert it to dds. Worked fine.
In passing, have you figured out how to use different fonts, I mean other than the the limited ones in the enum.
I know there is a file called fontsmap.xml, going to see if I can add additional fonts.
Monospace is interesting, it draws a rectangle on the screen instead of a period.
