How to Make a Retro Style 3D FPS in the Godot Game Engine

Set up a 3D scene in Godot to build a retro style fps world by tiling ground textures, importing assets, and instancing walls with colliders.

Set up lighting and skybox in Godot by creating a procedural sky, adjusting horizon and sky colors, and adding a directional light with sunset tones for a creepy apocalyptic scene.

Learn to implement player movement and mouse aim in Godot using a kinematic body, capsule collider, and move‑and‑slide with snap for grounded, responsive control.

Implement a weapon manager in Godot, create weapon nodes as children, manage slots and unlocks, and switch weapons with hotkeys and the scroll wheel. Test with an in-scene debug rig.

Import and organize weapon models in Godot by creating a weapons folder, importing 3D models and textures, adjusting shaders, and preparing gun assets for a retro style 3D FPS.

Set up weapon graphics as spatial nodes, scale to prevent wall clipping, and create idle and attack animations for machete, machine gun, shotgun, rocket launcher with keyframes.

Build a retro style bullet hit effect in Godot by using a 3D scene with a particle system and a quad mesh circle texture, plus a one-shot emission.

Learn to implement hitscan bullets in Godot by creating a weapon script, preloading hit effects, and using a ray intersection to detect hits, apply damage, and spawn oriented impact effects.

Create a modular weapon system in Godot, using a shared weapon script with hit scan bullets, bullet emitters, fire point alignment to the camera, and configurable ammo and attack rate.

Create a modular shotgun system in Godot by adding bullet emitters via a spatial node, tuning rotations for spread, wiring muzzle flash, and setting attack rate and damage.

Create a rocket launcher in Godot by instantiating rockets, setting damage and transforms, and adding a muzzle flash. Connect the fired signal and tweak the explosion to stop stray particles.

Add crosshair textures to each weapon, center them via the inspector, organize them in a cross-hairs folder, name each texture, and toggle visibility in the weapon script.

Implement weapon bobbing for a retro 3d fps in Godot by syncing the weapon manager with velocity and grounded state using an animation player to move the weapon while running.

Import and organize enemy meshes in a new enemies folder, configure textures with filtering disabled and enable back-face culling, then verify looping animations (names end with _loop) import in Godot.

Set up hit boxes for the monster by attaching capsule collision shapes to bones, marking the head as a weak spot for critical damage, and wiring hurt and damage signals.

Set up monster chase by facing the player, using a navigation node and simple path to the next node, then move with the character mover while ignoring rotation.

Set up enemy melee attacks in Godot by defining attack range and rate, wiring a timer, enabling attack states, aiming at the player, and triggering damage via an animation event.

Design a fireball projectile in Godot by converting a rocket into a fireball, adding a sprite 3D smoke trail, animation, and a one-shot particle burst, plus a fireball spawner.

Learn to create gib effects in Godot, configure blood spray particles, implement gravity and bounce with velocity retention, and use a pre-spawned gib pool.

Create health and ammo pickups in Godot by adding an area with collision, a spin animation, and a pickup script; duplicate for machine gun, shotgun, rocket, and health.

Configure a pickup manager in Godot to handle health and ammo pickups, connect area signals, and synchronize with the health and weapon managers to update player health and ammo counts.

Create a health and ammo stats display in Godot by updating a label with health and ammo values, showing infinity when ammo is negative.

Create a health effects overlay with a color rectangle and an animation player to flash red on hurt and green on heal, using keyframes for visibility and alpha.

Learn to export a Godot game by installing export templates, selecting presets for Windows, Mac, and Linux, and exporting to a folder with fullscreen testing.
