Levels in Isetta are comparable to scenes in Unity.

Creating Levels

To create a level, add the following .h and .cpp file.


#pragma once
#include <IsettaEngine.h>
using namespace Isetta;

void Load() override;
void OnUnload() override;


#include <IsettaEngine.h>
#include "LEVEL_NAME.h"

using namespace Isetta;

void LEVEL_NAME::Load() {
    // Level NEEDS a camera
    Entity* cameraEntity = Entity::Instantiate("Camera");
    cameraEntity->SetTransform(Math::Vector3{0, 5, 10}, Math::Vector3{-15, 0, 0},

void LEVEL_NAME::OnUnload() {
    // Anything you might need to do on the level unloading
    // Entity's will be destructed/destroyed on actual level unload

  • To load the file you just added as start up level, go to your user.cfg and set start_level to LEVEL_NAME.

Essential API

  • LevelManager::Instance().LoadLevel("levelName"): programmatically load levels
  • LevelManager::Instance().loadedLevel: get information about current level

Example Levels
