Sdl3 Tutorial Online

// Player movement speed #define PLAYER_SPEED 5

return sprite;

I'll help you create a practical SDL3 tutorial with a complete feature implementation. Let's build a with keyboard controls - a perfect foundation for games. SDL3 Sprite Animation Tutorial Prerequisites # Install SDL3 (Ubuntu/Debian) sudo apt install libsdl3-dev macOS brew install sdl3 Windows - download from libsdl.org Complete Example: Animated Sprite with Movement // sdl3_animation_tutorial.c #include <SDL3/SDL.h> #include <stdio.h> #include <stdbool.h> // Screen dimensions #define SCREEN_WIDTH 800 #define SCREEN_HEIGHT 600

// Get texture dimensions int tex_width, tex_height; SDL_GetTextureSize(sprite->texture, &tex_width, &tex_height); sdl3 tutorial

// Clean up resources void destroy_animated_sprite(AnimatedSprite* sprite) if (sprite) if (sprite->texture) SDL_DestroyTexture(sprite->texture); free(sprite);

// Cleanup destroy_animated_sprite(player); SDL_DestroyRenderer(renderer); SDL_DestroyWindow(window); SDL_Quit();

SDL_Event event; bool running = true; Uint64 last_time = SDL_GetTicks(); Uint64 current_time; float delta_time; // Player movement speed #define PLAYER_SPEED 5 return

// Update animation frame void update_animation(AnimatedSprite* sprite) if (sprite->moving) sprite->frame_counter++; if (sprite->frame_counter >= sprite->frame_delay) sprite->frame_counter = 0; sprite->current_frame = (sprite->current_frame + 1) % FRAME_COUNT;

// Create sprite with placeholder AnimatedSprite* player = create_animated_sprite(renderer, "placeholder"); if (player) // Replace with our placeholder texture SDL_DestroyTexture(player->texture); player->texture = placeholder_tex; // Re-initialize frames for 64x64 placeholder for (int i = 0; i < FRAME_COUNT; i++) player->frames[i].x = i * 64; player->frames[i].y = 0; player->frames[i].w = 64; player->frames[i].h = 64;

SDL_Texture* placeholder_tex = SDL_CreateTextureFromSurface(renderer, surface); SDL_DestroySurface(surface); // Cleanup destroy_animated_sprite(player)

// Add multiple animations (idle, run, jump) typedef enum ANIM_IDLE, ANIM_RUN, ANIM_JUMP AnimationState; // Add collision detection bool check_collision(SDL_Rect a, SDL_Rect b);
