The first person 3D camera does not point to target

[wlxmhls]

Hello, I tried the example code for 1st person 3D camera mode. When the window initialized, it seems the camera point to somewhere, NOT the target. Do you have the experience?

Here is the code:

#include "raylib.h"

int main(void)
{
    // Initialization
    //--------------------------------------------------------------------------------------
    const int screenWidth = 800;
    const int screenHeight = 450;

    InitWindow(screenWidth, screenHeight, "raylib [core] example - 3d camera mode");

    // Define the camera to look into our 3d world
    Camera3D camera = { 0 };
    camera.position = (Vector3){ 0.0f, 10.0f, 10.0f };  // Camera position
    camera.target = (Vector3){ 0.0f, 0.0f, 0.0f };      // Camera looking at point
    camera.up = (Vector3){ 0.0f, 1.0f, 0.0f };          // Camera up vector (rotation towards target)
    camera.fovy = 45.0f;                                // Camera field-of-view Y
    camera.projection = CAMERA_PERSPECTIVE;             // Camera mode type

    SetCameraMode(camera, CAMERA_FIRST_PERSON);  // ADDED BY ME.

    Vector3 cubePosition = { 0.0f, 0.0f, 0.0f };

    SetTargetFPS(60);               // Set our game to run at 60 frames-per-second
    //--------------------------------------------------------------------------------------

    // Main game loop
    while (!WindowShouldClose())    // Detect window close button or ESC key
    {
        // Update
        //----------------------------------------------------------------------------------
        // TODO: Update your variables here
        //----------------------------------------------------------------------------------
        UpdateCamera(&camera);  //ADDED BY ME

        // Draw
        //----------------------------------------------------------------------------------
        BeginDrawing();

            ClearBackground(RAYWHITE);

            BeginMode3D(camera);

                DrawCube(cubePosition, 2.0f, 2.0f, 2.0f, RED);
                DrawCubeWires(cubePosition, 2.0f, 2.0f, 2.0f, MAROON);

                DrawGrid(10, 1.0f);

            EndMode3D();

            DrawText("Welcome to the third dimension!", 10, 40, 20, DARKGRAY);

            DrawFPS(10, 10);

        EndDrawing();
        //----------------------------------------------------------------------------------
    }

    // De-Initialization
    //--------------------------------------------------------------------------------------
    CloseWindow();        // Close window and OpenGL context
    //--------------------------------------------------------------------------------------

    return 0;
}

The initial state of the window:

The cube is at the target position. It shoud be sawn at window start, right?

@wlxmhls Just tested it righ now and it works as expected for me. Are you using latest raylib from GitHub master banch? What OS/platform are you testing on?

EDIT: Just noticed you added SetCameraMode(camera, CAMERA_FIRST_PERSON);

Yeah, it re-initializes target by default, it's a know issue but not simple to solve...

Thanks!
