Code Examples for Unreal Engine & LÖVE

Unreal Engine

This Unreal Engine script is a basic AI patrol code for NPCs (Non-Player Characters). We assume that you have context on AI and pathfinding in Unreal. The code requires the AI Behavior Toolkit plugin and Unreal Engine version 4.25 or later.

// AI Patrol Code
void AMyAICharacter::Patrol() {
  if (PatrolPoints.Num() > 0) {
    MoveToLocation(PatrolPoints->GetActorLocation());
  }
}

void AMyAICharacter::OnMoveCompleted(FAIRequestID RequestID, const FPathFollowingResult& Result) {
  Super::OnMoveCompleted(RequestID, Result);

  if (Result.Code == EPathFollowingResult::Success) {
    PatrolPointIndex++;
    if (PatrolPointIndex >= PatrolPoints.Num()) {
      PatrolPointIndex = 0;
    }
    Patrol();
  }
}
    

LÖVE

The following LÖVE code snippet is a simple physics engine for a 2D game, showcasing the usage of LÖVE’s built-in Box2D physics wrapper. You require LÖVE 11.3 or later version to optimally run this script.

-- A basic physics engine in LÖVE
function love.load()
    love.physics.setMeter(64) 
    world = love.physics.newWorld(0, 9.81*64, true)

    objects = {} 
    objects.ground = {}
    objects.ground.body = love.physics.newBody(world, 650/2, 650-50/2) 
    objects.ground.shape = love.physics.newRectangleShape(650, 50) 
    objects.ground.fixture = love.physics.newFixture(objects.ground.body, objects.ground.shape)

    objects.ball = {}
    objects.ball.body = love.physics.newBody(world, 650/2, 650/2, "dynamic") 
    objects.ball.shape = love.physics.newCircleShape(20) 
    objects.ball.fixture = love.physics.newFixture(objects.ball.body, objects.ball.shape, 1) 
end

function love.update(dt)
    world:update(dt) 
end

function love.draw()
    love.graphics.rectangle("line", objects.ground.body:getX(), objects.ground.body:getY(), objects.ground.shape:getWidth(), objects.ground.shape:getHeight())
    love.graphics.circle("line", objects.ball.body:getX(), objects.ball.body:getY(), objects.ball.shape:getRadius())
end
