Caribbean Beach Open World · Character + Scene Prompts Build a Playable World

HappyOysterGame FootageOceanRealisticFitnessCreative39s
Using one character reference image and one beach reference image, this builds a third-person beach in the HappyOyster world model where you can walk, sprint, jump, and crouch with the keyboard — footprints left in the sunset sand slowly wash away with the waves. The prompt is split into two parts, character and scene, each spelling out the controllable actions and what must not appear in the environment.

Freya Lux is the single playable character: an adult athletic woman with blue eyes and blonde hair in a ponytail. Match the uploaded character reference exactly: charcoal sleeveless athletic top, navy full-length leggings and light-colored sneakers. Preserve her face, body proportions, hairstyle and clothing throughout the adventure. The reference shows front and back views of ONE person; create only one Freya. Third-person exploration, with the camera initially behind Freya and slightly above shoulder height, showing her full body and the ground ahead. The camera follows smoothly and can rotate to look around while keeping her visible. Freya can walk forward and backward, move sideways, turn, sprint, jump and crouch under player control. Walking uses natural alternating steps and relaxed arm movement. Sprinting increases her stride and arm swing, and her ponytail bounces naturally. Jumping lifts both feet off the sand; she lands with bent knees and regains her balance. Crouching lowers her body by bending her knees and hips; standing restores her normal posture. Her shoes remain grounded while walking, leaving shallow footprints in damp sand. Running and landing raise small puffs of loose dry sand. When idle, she stands calmly with subtle breathing. Her hands are empty. This is a peaceful exploration with no combat or equipment.
✍️ Editor’s Notes

The key move in this character prompt is nailing down 'singularity': it first fixes the look with names and specifics — blue eyes, blonde ponytail, top and pants specified down to the shade — then adds a line clarifying the reference shows the front and back of the same person and only one character should be built, so the world model doesn't mistake two reference angles for two different people. The action section skips abstract words like 'agile' or 'natural' and instead breaks things down by control type: walking, sprinting, jumping, crouching each get a concrete physical response — stride change, bent knees, ponytail bounce — which makes it easier for a playability-focused world model to map onto a concrete animation state machine. The ending draws a clear scene boundary with 'empty hands' and 'no combat, no equipment,' keeping the model from adding props on its own.

Use the uploaded beach image as the environment reference. A quiet Caribbean beach at sunset, with a gently curved shoreline, pale sand, turquoise water and palm trees along the inland edge. Preserve the coastline, warm golden light and uncluttered composition. Place Freya on the firm sand near the waterline, initially facing along the beach. Leave a broad, continuous stretch of open sand ahead for walking, sprinting, jumping and crouching. Keep the beach connected and its geography consistent as the player moves or rotates the camera. Small waves continuously travel from the open sea toward the shore. Each wave forms a low crest, breaks into soft white foam and spreads a thin sheet of water across the sand. The water then recedes, leaving wet reflective sand. Foam gradually dissolves; wave timing and height vary slightly for a natural rhythm. Freya's footsteps leave shallow impressions in damp sand. Gentle waves wash over footprints at the waterline and gradually erase them. If she steps into the shallow wash, her shoes create small splashes and ripples; the water flows around her feet and retreats naturally. Palm fronds sway gently in the breeze. Golden reflections shimmer across the moving water and wet sand. Freya casts a soft, consistent shadow on the beach. Ambient sound: gentle surf, receding water, rustling palms and footsteps that match her movement. Maintain the same sunset lighting during exploration. No additional people, buildings, boats, vehicles, dramatic weather or scene cuts.
✍️ Editor’s Notes

The core of this scene prompt is giving 'endless walkability' a physical basis: it first locks the coastline and composition with the reference image, then explicitly tells the world to leave the player a continuous, open stretch of sand, and stresses that the terrain must stay consistent as the camera moves or rotates — the key difference between an interactive scene and a static render, which needs an explicit reminder so the model doesn't let the terrain jump around. The waves are written in fine detail across four stages — crest, breaking into foam, spreading a water film, receding into wet reflection — plus a specific line about footprints being washed away by the waves, tying environmental motion directly to the character's actions, which is far easier for the model to execute as an interactive effect than simply writing 'beautiful waves.' The closing exclusion list — no people, buildings, boats, vehicles, sudden weather, or scene cuts — draws the scene's boundary.
