# Making the Entrance We are now onto the last part of our floor tutorial!\ Congratulations. You've almost finished. now we just need to make the entrance. For this example, I will make a pit to load the floor, but you can use other things as well. Make the entrance of your floor in RAT. Do not add any pits. Go back to `ModRoomPrefabs` and add a new PrototypeDungeonRoom ```csharp public static PrototypeDungeonRoom Keep_Entrance_Room; ``` Ideally, we want our room to have an icon, if we want this we go add new objects to our asset bundle, one empty gameobject, and one texture (the icon). Go into `ModPrefabs` and add `public static GameObject Entrance_Icon;`\ in InitCustomPrefabs drop ```csharp Entrance_Icon = ModAssets.LoadAsset("Entrance_Icon"); ItemAPI.ItemBuilder.AddSpriteToObject(Entrance_Icon, ModAssets.LoadAsset("Entrance_Icon"), false, false); ``` inside the InitCustomRoom add ```csharp Keep_Entrance_Room = RoomFactory.BuildFromResource("DPSMod/Resources/ModRooms/Keep_Entrance_Room.room"); Keep_Entrance_Room.associatedMinimapIcon = ModPrefabs.Entrance_Icon; //not required ``` ![](https://1229800202-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-MQAkTlyeVttU3CJdmYk%2F-Mg3oFCvDGJY9gxKfWQQ%2F-Mg3w_yPNRxUdA9YpcWa%2Fimage.png?alt=media\&token=02718e1e-51d1-4837-9ad8-4902653f662e) (Tiny pumpkin is the room icon lol. its blurry here but i just forgot to change its filter mode to point) now we head back towards `FloorNameDungeonFlows`\ inside `InitDungeonFlows` This section has to do with our entrance ```csharp m_KeepEntranceRooms = ScriptableObject.CreateInstance(); m_KeepEntranceRooms.includedRoomTables = new List(0); m_KeepEntranceRooms.includedRooms = new WeightedRoomCollection() { elements = new List() { //we will place the entrance to our floor here. } }; SecretFloorNameEntranceInjector = new ProceduralFlowModifierData() { annotation = "Secret Floor Entrance Room", DEBUG_FORCE_SPAWN = false, OncePerRun = false, placementRules = new List() { ProceduralFlowModifierData.FlowModifierPlacementType.RANDOM_NODE_CHILD }, roomTable = m_KeepEntranceRooms, // exactRoom = SewersInjectionData.InjectionData[0].exactRoom, exactRoom = null, RequiresMasteryToken = false, chanceToLock = 0, selectionWeight = 1, chanceToSpawn = 1, RequiredValidPlaceable = null, prerequisites = new DungeonPrerequisite[0], CanBeForcedSecret = true, RandomNodeChildMinDistanceFromEntrance = 0, exactSecondaryRoom = null, framedCombatNodes = 0, }; CastleInjectionData.InjectionData.Add(SecretFloorNameEntranceInjector); ``` here we add our room ```csharp m_KeepEntranceRooms.includedRooms = new WeightedRoomCollection() { elements = new List() { //we will place the entrance to our floor here. } }; ``` ```csharp m_KeepEntranceRooms.includedRooms = new WeightedRoomCollection() { elements = new List() { ModRoomPrefabs.GenerateWeightedRoom(ModRoomPrefabs.Keep_Entrance_Room, Weight: 1f) } }; ``` we can add more rooms if we want some variance and it will randomly select one of these rooms. Add this to your toolbox: ```csharp public static SpeculativeRigidbody GenerateOrAddToRigidBody(GameObject targetObject, CollisionLayer collisionLayer, PixelCollider.PixelColliderGeneration colliderGenerationMode = PixelCollider.PixelColliderGeneration.Tk2dPolygon, bool collideWithTileMap = false, bool CollideWithOthers = true, bool CanBeCarried = true, bool CanBePushed = false, bool RecheckTriggers = false, bool IsTrigger = false, bool replaceExistingColliders = false, bool UsesPixelsAsUnitSize = false, IntVector2? dimensions = null, IntVector2? offset = null) { SpeculativeRigidbody m_CachedRigidBody = GameObjectExtensions.GetOrAddComponent(targetObject); m_CachedRigidBody.CollideWithOthers = CollideWithOthers; m_CachedRigidBody.CollideWithTileMap = collideWithTileMap; m_CachedRigidBody.Velocity = Vector2.zero; m_CachedRigidBody.MaxVelocity = Vector2.zero; m_CachedRigidBody.ForceAlwaysUpdate = false; m_CachedRigidBody.CanPush = false; m_CachedRigidBody.CanBePushed = CanBePushed; m_CachedRigidBody.PushSpeedModifier = 1f; m_CachedRigidBody.CanCarry = false; m_CachedRigidBody.CanBeCarried = CanBeCarried; m_CachedRigidBody.PreventPiercing = false; m_CachedRigidBody.SkipEmptyColliders = false; m_CachedRigidBody.RecheckTriggers = RecheckTriggers; m_CachedRigidBody.UpdateCollidersOnRotation = false; m_CachedRigidBody.UpdateCollidersOnScale = false; IntVector2 Offset = IntVector2.Zero; IntVector2 Dimensions = IntVector2.Zero; if (colliderGenerationMode != PixelCollider.PixelColliderGeneration.Tk2dPolygon) { if (dimensions.HasValue) { Dimensions = dimensions.Value; if (!UsesPixelsAsUnitSize) { Dimensions = (new IntVector2(Dimensions.x * 16, Dimensions.y * 16)); } } if (offset.HasValue) { Offset = offset.Value; if (!UsesPixelsAsUnitSize) { Offset = (new IntVector2(Offset.x * 16, Offset.y * 16)); } } } PixelCollider m_CachedCollider = new PixelCollider() { ColliderGenerationMode = colliderGenerationMode, CollisionLayer = collisionLayer, IsTrigger = IsTrigger, BagleUseFirstFrameOnly = (colliderGenerationMode == PixelCollider.PixelColliderGeneration.Tk2dPolygon), SpecifyBagelFrame = string.Empty, BagelColliderNumber = 0, ManualOffsetX = Offset.x, ManualOffsetY = Offset.y, ManualWidth = Dimensions.x, ManualHeight = Dimensions.y, ManualDiameter = 0, ManualLeftX = 0, ManualLeftY = 0, ManualRightX = 0, ManualRightY = 0 }; if (replaceExistingColliders | m_CachedRigidBody.PixelColliders == null) { m_CachedRigidBody.PixelColliders = new List { m_CachedCollider }; } else { m_CachedRigidBody.PixelColliders.Add(m_CachedCollider); } if (m_CachedRigidBody.sprite && colliderGenerationMode == PixelCollider.PixelColliderGeneration.Tk2dPolygon) { Bounds bounds = m_CachedRigidBody.sprite.GetBounds(); m_CachedRigidBody.sprite.GetTrueCurrentSpriteDef().colliderVertices = new Vector3[] { bounds.center - bounds.extents, bounds.center + bounds.extents }; // m_CachedRigidBody.ForceRegenerate(); // m_CachedRigidBody.RegenerateCache(); } return m_CachedRigidBody; } ``` now we need a new object in our assetbundle. we will place this in our entrance room. Go to ModPrefabs and add `public static GameObject FloorNameEntrance;` Get it like so\ `FloorNameEntrance = ModAssets.LoadAsset("FloorNameEntrance");`\ you can add a sprite to this object if you wish. \ create a new file called KeepEntranceControllerthat inherits from BraveBehaviour, IPlaceConfigurable. just copy ***AAAALLLLLLLL*** this in ```csharp public KeepEntranceController() { targetLevelName = "tt_floorname"; PitOffset = new IntVector2(5, 2); m_Triggered = false; m_Destroyed = false; } public string targetLevelName; public IntVector2 PitOffset; private bool m_Triggered; private bool m_Destroyed; private RoomHandler m_ParentRoom; private IEnumerator Start() { yield return null; while (GameManager.Instance.IsLoadingLevel && Dungeon.IsGenerating) { yield return null; } yield return null; //IntVector2 baseCellPosition = (transform.position.IntXY(VectorConversions.Floor) + new IntVector2(4, 1.5)); // specRigidbody.OnHitByBeam = (Action)Delegate.Combine(specRigidbody.OnHitByBeam, new Action(HandleBeamCollision)); GameObject PitManager = new GameObject("Pit Manager") { layer = 0 }; PitManager.transform.position = (transform.position + new Vector3(5, 1.5f)); tk2dSprite PitDummySprite = PitManager.AddComponent(); //Toolbox.DuplicateSprite(PitDummySprite, null); tk2dSprite pitSprite = PitManager.GetComponent(); pitSprite.renderer.enabled = false; toolbox.GenerateOrAddToRigidBody(PitManager, CollisionLayer.Trap, PixelCollider.PixelColliderGeneration.Manual, IsTrigger: true, dimensions: new IntVector2(2, 2)); KeepEntrancePitController HallPitManager = PitManager.AddComponent(); HallPitManager.targetLevelName = targetLevelName; yield break; } /*private void HandleBeamCollision(BasicBeamController obj) { GoopModifier component = obj.GetComponent(); if (component && component.goopDefinition != null && component.goopDefinition.CanBeIgnited && component.goopDefinition.fireEffect != null) { OnFireStarted(); } }*/ public void ConfigureOnPlacement(RoomHandler room) { m_ParentRoom = room; IntVector2 basePosition = (transform.position.IntXY(VectorConversions.Floor) + PitOffset); IntVector2 cellPos = basePosition; IntVector2 cellPos2 = (basePosition + new IntVector2(1, 0)); IntVector2 cellPos3 = (basePosition + new IntVector2(1, 1)); IntVector2 cellPos4 = (basePosition + new IntVector2(0, 1)); CellData cellData = GameManager.Instance.Dungeon.data[cellPos]; CellData cellData2 = GameManager.Instance.Dungeon.data[cellPos2]; CellData cellData3 = GameManager.Instance.Dungeon.data[cellPos3]; CellData cellData4 = GameManager.Instance.Dungeon.data[cellPos4]; cellData.type = CellType.PIT; cellData2.type = CellType.PIT; cellData3.type = CellType.PIT; cellData4.type = CellType.PIT; cellData.forceAllowGoop = false; cellData2.forceAllowGoop = false; cellData3.forceAllowGoop = false; cellData4.forceAllowGoop = false; cellData.fallingPrevented = false; cellData2.fallingPrevented = false; cellData3.fallingPrevented = false; cellData4.fallingPrevented = false; } private void Update() { } private void LateUpdate() { } protected override void OnDestroy() { m_Destroyed = true; base.OnDestroy(); } } public class KeepEntrancePitController : DungeonPlaceableBehaviour, IPlaceConfigurable { public KeepEntrancePitController() { targetLevelName = "tt_floorname"; } public string targetLevelName; private void Start() { SpeculativeRigidbody Rigidbody = specRigidbody; Rigidbody.OnEnterTrigger = (SpeculativeRigidbody.OnTriggerDelegate)Delegate.Combine(Rigidbody.OnEnterTrigger, new SpeculativeRigidbody.OnTriggerDelegate(HandleTriggerEntered)); SpeculativeRigidbody Rigidbody2 = specRigidbody; Rigidbody2.OnExitTrigger = (SpeculativeRigidbody.OnTriggerExitDelegate)Delegate.Combine(Rigidbody2.OnExitTrigger, new SpeculativeRigidbody.OnTriggerExitDelegate(HandleTriggerExited)); } private void HandleTriggerEntered(SpeculativeRigidbody specRigidbody, SpeculativeRigidbody sourceSpecRigidbody, CollisionData collisionData) { PlayerController component = specRigidbody.GetComponent(); if (component) { component.LevelToLoadOnPitfall = targetLevelName; } } private void HandleTriggerExited(SpeculativeRigidbody specRigidbody, SpeculativeRigidbody sourceSpecRigidbody) { PlayerController component = specRigidbody.GetComponent(); if (component) { component.LevelToLoadOnPitfall = string.Empty; } } public void ConfigureOnPlacement(RoomHandler room) { } private void Update() { } protected override void OnDestroy() { base.OnDestroy(); } } ``` make sure to change values according to your needs. now we head back to ModPrefabs and do ```csharp FloorNameEntrance.AddComponent(); ``` And in ModRoomPrefabs do ``` RoomBuilder.AddObjectToRoom(Keep_Entrance_Room, new Vector2(3.5f, 12) /* needs tweaking */ , toolbox.GenerateDungeonPlacable(ModPrefabs.FloorNameEntrance, useExternalPrefab: true)); ``` tada! congratulations, you have just done one of the hardest things in modding! nice work and i cant wait to see the results :).
