Set up a new Unreal Engine 5.7.4 multiplayer dungeon crawler project with a blank starter, blueprint focus (C++ option), a demo level, and Steam online integration via Advanced Sessions.

Create a default game instance blueprint, GIGameInstance, as the base for all instances. The game instance runs on every client and the server and handles saving and loading across levels.

Create a GameplayController blueprint to capture inputs from keyboard, mouse, and joystick, and push them from client to server so attacks execute with server authority.

Implement four base actions for all characters in Unreal Engine 5, mapping input booleans and wiring server-side action calls with pressed and released states for multiplayer.

Create a base character that triggers a multicast attack montage on all clients from the server. Implement a replicated isAttacking flag to prevent movement during the attack.

Integrate the swordsman attack with an animation montage and state notifies to toggle a collision box on the server, enabling damage to non player actors using a player tag.

Learn how to streamline character communication by replacing casts with blueprint interfaces, reducing hard references and memory usage for swordsman action and end attack in a multiplayer dungeon crawler.

Update interfaces to retrieve speed from velocity in animation blueprints, remove hard references, clean up assets, and streamline the player base and swordsman references for a lean multiplayer dungeon crawler.

Master the swordsman blink ability in Unreal Engine 5 dungeon crawler multiplayer, moving from point a to point b with line traces, collision boxes, and a timeline.

Learn to implement a smooth swordsman blink in multiplayer by using client, server, and multicast calls, replicating the is blinking state to drive animations and interfaces.

Execute a ground smash by pressing the attack button, launching upward to hit surrounding enemies, using a sphere collision to detect targets and an action montage for swordsman action 4.

Design and implement a multiplayer HUD in Unreal Engine 5 using a widget blueprint, with health bar, mana bar, and gold indicators anchored to the bottom.

Set up nav mesh bounds volume and ai perception to let the enemy see players within 1500 unreal units, then pass sight updates to trigger chasing.

Implement enemy chasing in Unreal Engine by enabling go home, locating the closest player among scene players, moving with AI move to, and executing a primary attack montage.

Use an event dispatcher in the player base to broadcast death via handleDeathDispatch, so enemies listen, stop attacking the dead player, and update the chase array accordingly.

Unreal Engine 5 multiplayer dungeon crawler: handle player death and respawn by coordinating the server, player controller, and game controller to destroy the controlled pawn, unpossess, and respawn.

Debug and fix the swordsman block by wiring the check hit player return node, ensuring blocking consumes mana and applies health damage, in multiplayer combat.

Build and configure a multiplayer menu system in Unreal Engine 5 by setting up the main menu, multiplayer options, create session, and player count with widgets, borders, and text inputs.

Unreal Engine 5 builds the multiplayer widget, wiring the game and back buttons, clamps the player count from two to six, and passes the game name to start multiplayer game.

Learn to create a multiplayer session in Unreal Engine 5 by setting server name and max players, opening the level, and enabling a listen server.

Create a join game user interface with a session list, server name, and player count, wired to a join session flow and input mode handling.

Duplicate the create game menu into a find session menu, implement a refresh list with a throbber and widget switcher, and populate the session list for multiplayer.

Set up and test find sessions in a multiplayer dungeon crawler by wiring refresh list logic, handling a loading throbber, enabling two-player sessions, and validating join game flow.

Build and animate a mage for a multiplayer dungeon crawler in Unreal Engine 5, creating skeletal mesh, anim blueprint, blend space, and a tornado attack with death animation.

Set up a mage to fire a fireball in a multiplayer Unreal Engine 5 dungeon crawler, add fx variety pack, and implement server-side mana and attack logic.

Add an actor component for the mage that uses a timer to apply damage over time to enemies in a radius on the server, with adjustable damage and duration.

Build a full-screen character select UI with a border, grid panel, and swordsman/mage options, including hover and click interactions. Drive server-side character selection and switch to game input for multiplayer.

Discover how to fetch and replicate player info via the game state, updating a player info array on the server and rendering health and mana in the HUD.

Design a map generator blueprint to spawn the starting room and build a procedural dungeon, using a room exit list, overlap boxes, and a top down view.

Rename starting room to base room, import a dungeon floor, convert it to a blueprint, and place exit arrows to feed the map generator’s rooms and room exit list.

Spawn the next dungeon room by selecting a random exit from the current room using a seeded random stream and place the hallway BP_hallway at the exit point.

Expand the map generator to spawn multiple rooms, track the latest spawned room, and manage the exit list with a build delay to prevent overlaps while watching the dungeon grow.

Create an overlapping room system by adding a dedicated object channel and box collisions, then use blueprint logic in the map generator to detect and report room overlaps.

Restart the dungeon by resetting exits and destroying all rooms, then reset the random seed, reinitialize room count, and spawn the starting room to auto rebuild.

Replace the size map’s references with a data table driven approach using s_room_info and the dt level rooms data table to drive the map generator across levels.

Explore guaranteeing treasure, key, and boss rooms in a multiplayer Unreal Engine 5 dungeon by designing a map generator that spawns required rooms and enforces order.

Spawn the final room as the last area of the dungeon using a dedicated last room workflow and a data table entry to mark the end of the level.

Build a better dungeon room in Unreal Engine 5 by shaping geometry, adding walls and exits, and organizing with a bp base room blueprint for scalable levels.

Debug the dungeon generator in Unreal Engine 5 by validating overlaps, using a validated get for spawns, and fixing restart dungeon loops and seed handling.

Debug and refine dungeon layout by adjusting room sizes and collision between rooms, reshuffling randomization, and testing with larger dungeon rooms to achieve coherent, playable multiplayer maps.

Refine a multiplayer dungeon generator in Unreal Engine 5 by identifying unused exits, filling gaps, and conditionally spawning walls or objects to complete the map.

Create gap fillers for each dungeon exit in Unreal Engine 5 multiplayer, using bp gap filler actors, ensure replication, and align rotation to clean gaps.

Learn to run map generation on the server, replicate rooms to clients, and spawn players after the level build completes using a replicated game state flag and a loading hud.

Finish the procedural dungeon by implementing the final exit room, end-of-level box collision, and level loading, while adding pickups and enemy spawners and fixing the exit-point bug.

Duplicate level one to create level two, change the seed to vary map layouts, and configure last and treasure rooms, then use server travel to start the next level.

Create a save game blueprint to carry player data between levels, including name, chosen class, health, mana, and gold, stored in a save game data structure.

Save player data, load the next level, and seamlessly transition in a multiplayer Unreal Engine 5 dungeon crawler by saving game data, loading from slot, and possessing the correct pawn.

Add a nav mesh bound volume and enable dynamic runtime navigation so enemies chase players across levels, while loading saved health and mana on spawn.
