Level¶

Levels in Isetta are comparable to scenes in Unity.

Creating Levels¶

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

LEVEL_NAME.h

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

DEFINE_LEVEL(LEVEL_NAME)
void Load() override;
void OnUnload() override;
DEFINE_LEVEL_END

LEVEL_NAME.cpp

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

using namespace Isetta;

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

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¶

Level Inputs

Some of the levels have inputs, too. But they display badly here! Go to our Git repo to look like them!

Level Name	Level Description
`AILevel`	Level showing how navigation module works in the engine and how to use the particle system
`AudioLevel`	Level with 2D and 3D audio looping and one shot
`BVHLevel`	Level testing our dynamic AABB tree
`CollisionsLevel`	Level testing our collision intersections
`CollisionSolverLevel`	Level testing our collision solving system
`DebugLevel`	Level demoing our debug drawing capabilities
`EditorLevel`	Level showing the editor components: inspector, heirarchy, and console and level loading menu
`EmptyLevel`	Empty level to be used as a starting point for user created levels
`EventLevel`	Level demoing our event messaging system with sender and listener components
`ExampleLevel`	Level with an animating model and example component
`GUILevel`	Level demoing some of our GUI capabilities
`InputLevel`	Level demoing some of the input capabilities
