Collect the Gems is a game where you run and jump around a small world to find three hidden gems. Each gem spins to catch your eye, and when you touch one it disappears, plays a sound, and updates the on-screen counter. When all gems are collected, you get a “You found them all!” message and a celebration sound.
This project demonstrates player movement with physics, collision-based pickup logic, counters/variables, win conditions, event-driven animations, and feedback (text + sound).
Try it out
1. Open Flock XR and go to the Demo menu. 2. Select 💎 Collect the gems 3. Press Play. 4. Use W/A/S/D to move, and Space to jump. Hold left mouse to look. 5. Find the three gems. You should see: – gems spinning in place – a sound and “Gem collected!” when you touch one – the on-screen “gems left” count going down – a “You found them all!” message and a win sound when you reach zero
Explore the code
Open the code and look for these parts:
A reusable “stairs” function A custom function called stairs(levels, width, x, z) that uses a loop to create steps. This is a great example of building level pieces without manually placing every block.
A playable character A character is loaded, given dynamic physics, with the camera set to follow. A forever loop checks for input: moving forward/back/left/right and applying a jump force. It also uses a jumping variable plus a touching surface check so you can’t jump forever in mid-air.
Jump animations using broadcasts When you jump, the project broadcasts “jumped” and plays Jump sequence of animations. When you land, it broadcasts “landed” and switches back to Idle.
Gems + visual feedback Three gem objects are loaded (Gem1/2/3), highlighted/alpha adjusted, and continuously rotated in a forever loop so they sparkle and feel “collectable”.
Collecting a gem (collision pickups) Three on collision blocks detect when the player intersects each gem. Each one: – hides the gem – subtracts 1 from gems left – plays a sound – updates the “gems left” UI text – makes the player say “Gem collected!”
Win condition A forever loop checks: if gems left == 0 and won == false, set won to true, wait 1 second, then broadcast win. The on event “win” block prints “You found them all!” and plays a victory sound.
Remix ideas
Try extending the project with your own ideas:
Add more gems and update the “gems left” starting value.
Add a “danger zone” (lava/water) that resets the player to the start if they fall in.
Add a timer (“Time: 32s”) and show a best time when the player wins.
Make gems worth different points (small = 1, big = 3) and track a score instead of a gem countdown.
Add a locked area that only opens when all gems are collected.
A similar project you could create
Create a checkpoint trail mini-game: – Reuse the same player movement + jump + camera follow code. – Replace gems with glowing checkpoints. – When the player touches a checkpoint, hide it and show the next checkpoint. – Keep a count of “checkpoints cleared”. – After the final checkpoint, trigger a win message and sound. It’s the same core pattern (spinning/visible targets + collision pickups + counter + win condition), but adds a set unlock order to gameplay.
