Prerequisites

• CMake (3.10 or higher)
• SDL2
• SDL2_image
• SDL2_ttf
• C++17 compatible compiler

Building

mkdir -p build
cd build
cmake ..
cmake --build .

Ubuntu/Mint packages

sudo apt install -y build-essential cmake libsdl2-dev libsdl2-image-dev libsdl2-ttf-dev

Running

After building, run the game from the project root:

cd ..
./bin/SDLGame

Current gameplay

There are two ball modes you can toggle between:

• Soccer ball (blue): kick/dribble style control.
• Basketball (orange): energy-based vertical bounces + mid-air shooting.

A small HUD is shown in the top-left with the current ball mode, position, velocity, and (for basketball) energy.

Controls

General

• ESC: quit

Gameplay

• Arrow keys / A,D: move left/right
• Space: bounce / jump timing (also used for “bounce next to” interactions)
• TAB: toggle ball mode (Soccer ↔ Basketball)

Basketball mode

• E: shoot (only when the player and ball are touching and both are in the air)

Editor

• P: toggle editor mode
• 1: place solid platform
• 2: place fall-through platform
• 3: set start point
• 4: set finish point
• 5: delete platform
• 6: place basket target
• Mouse left click: place the selected item (grid-snapped)
• Arrow keys (in editor): move camera by half a screen
• S: save level to level.txt
• L: load level from level.txt

Level format

Levels are stored in level.txt. Newer versions append basket targets after the platform list. Older level.txt files (without baskets) should still load.
