Good idea! 😀 ---

I added the player model, and it is already able to jump! 🙂 - [https://playground.babylonjs.com/#9GE7HV#16](https://playground.babylonjs.com/#9GE7HV#16) ---

Now I want to see the rest of the anims 😃 Nice job! ---

Oh yes sorry wrong link. The one you shared is built with ammo js, but I think the controls are pretty similar. I will share my updated repo after removing some stuff if you still want to have a look. I suppose the only difference between what was shared my implementation is that I also use the camera angle to calculate the input vector. ```auto public move(inputVector: Vector3, isSprinting: boolean, animationRatio: number) { let forward = this.camera.getForwardRay().direction; forward.y = 0; // Ensure horizontal movement only forward.normalize(); const right = Vector3.Cross(Vector3.Up(), forward).normalize(); let moveDirection = forward.scale(inputVector.z).add(right.scale(inputVector.x)); if (!moveDirection.equals(Vector3.Zero())) { moveDirection = moveDirection.normalize(); } // Apply animation ratio directly to base speed for frame rate independence const baseSpeed = 10; // Base speed adjusted by animation ratio const sprintMultiplier = isSprinting && this.stamina > 0 ? 2 : 1; // Determine sprint multiplier let adjustedSpeed = baseSpeed * sprintMultiplier; // Adjusted speed based on sprinting // Consume stamina if sprinting if (isSprinting && this.stamina > 0) { this.stamina -= this.sprintStaminaConsumptionRate * animationRatio; } // Apply the adjusted speed to the movement direction let velocity = this.mesh.physicsBody.getLinearVelocity(); let newVelocity = new Vector3(moveDirection.x * adjustedSpeed, velocity.y, moveDirection.z * adjustedSpeed); this.mesh.physicsBody.setLinearVelocity(newVelocity); // Logging const currentTime = performance.now(); if (currentTime - this.lastLogTime > 3000) { // console.log(`Sprint Multiplier: ${sprintMultiplier}`); // console.log(`Base Speed: ${baseSpeed}`); // console.log(`Adjusted Speed: ${adjustedSpeed}`); // console.log(`New Velocity: ${newVelocity}`); this.lastLogTime = currentTime; // Update the last log time } } public getWorldInputDirection(rawInput: Vector3): Vector3 { // Get camera's forward vector and adjust for horizontal movement let forward = this.camera.getForwardRay().direction; forward.y = 0; forward.normalize(); // Compute the right vector const right = Vector3.Cross(Vector3.Up(), forward).normalize(); // Compute move direction from raw input let moveDirection = forward.scale(rawInput.z).add(right.scale(rawInput.x)); if (!moveDirection.equals(Vector3.Zero())) { moveDirection = moveDirection.normalize(); } return moveDirection; } } ``` ---

Thank you very much. This code snippet is very informative, I wish I had seen it when I was first exploring character controller! But it’s still a reference for me now. ---

Wow! Good job 👏, expect to see the full movement animation. The animation part is what I want to achieve that I don’t know yet, due to the lack of skills. ---

There were some changes… 🙂 - [https://playground.babylonjs.com/#9GE7HV#24](https://playground.babylonjs.com/#9GE7HV#24) Added Walk and Run animations + animation blending. ![image](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/3X/f/5/f5caf28075e74679dde10168607147976ee03951.jpeg) ---

It’s awesome, the movement animation looks silky smooth. Thanks to you, I’ve learned a new skill. As a newbie to Babylonjs, I’m so happy. ---

Well, it’s just a draft. But probably I’ll develop it to the more robust and universal solution. [Previous page](https://forum.babylonjs.com/t/third-person-physics-character-controller/57357.md?page=1)
