Oasis by Decart ↗ - 3.Paste the following prompt into the description field, replacing the bracketed content with your own scenario:
The more detailed the environment description, the more stable the world generates frame by frame.
Oasis by Decart ↗PromptA [foggy medieval village] at [dawn]. The player starts near [an old stone well]. Surroundings include [wooden houses with thatched roofs, a dirt path, scattered barrels]. Atmosphere is [mysterious and quiet]. Lighting is [soft blue-grey with warm orange from distant torches].
What this prompt doesThe English prompt describes the world for the AI world model: replace [foggy medieval village] with your location type, [dawn] with time of day, [an old stone well] with the player's starting point, and the rest of the brackets with scene objects and atmosphere. The model generates world frames in real time based on this description. - 4.Click «Generate World» / «Play». Control the character with WASD keys and the mouse. Each frame is rendered by the model in real time - not a pre-recorded video, but live generation based on your actions.
In the first few seconds the world may «smear» and rebuild - this is normal for world models; wait 5 - 10 seconds for it to stabilize.
Oasis by Decart ↗ - 5.Record your screen while playing - use the built-in OS recorder (Win+G on Windows, Cmd+Shift+5 on macOS) or OBS Studio. Cut a 15 - 30 second clip with the most interesting moments of the world «coming alive».
To boost views, show the moment the world rebuilds in the first 3 seconds - it grabs attention.
OBS Studio ↗ - 6.Load the clip into CapCut, add a hook title: «AI generates a game in real time - no code needed». Add subtitles, export in 9:16 for Shorts/Reels or 16:9 for YouTube.
The free version of CapCut is enough for editing, subtitles, and watermark-free export.
