Hi,
you might use something like that:
the code in puzzle:
const objHeight = 1.5; const height = objHeight / 2 * app.camera.zoom * app.getHeight(); console.log(height);Hi,
unfortunately for touch controls you have to completely override the OrbitControls class which requires some knowledge of JavaScript.If that’s something which could be roughly build with puzzles, the type of navigation used in the VR Demo would greatly benefit from this.
Hi Thomas,
Here is how we do it. You can use this snippet as a basis for your own puzzle or with “exec script”:_handleCollisions() { if (!this._enableCollisions || this.collisionMeshes.length == 0) return; this._raycaster.ray.origin.copy(this.object.position); this._raycaster.far = this.storyHeight; const intersections = this._raycaster.intersectObjects(this.collisionMeshes, false); if (intersections.length > 0) { const intersection = intersections[0]; this.object.position.y = intersection.point.y + this.gazeLevel; this._onCollisionMesh = true; } else if (this._onCollisionMesh) { let minDistance = Infinity; for (const mesh of this.collisionMeshes) { if (!mesh.geometry.boundsTree) { console.warn('v3d.FirstPersonControls: no bounding tree found on ' + mesh.name); continue; } this._toMeshSpaceMatrix.copy(mesh.matrixWorld).invert(); this._lastIntersection.copy(this.object.position); this._lastIntersection.y -= this.gazeLevel; this._lastIntersection.applyMatrix4(this._toMeshSpaceMatrix); const target = this._ppTarget; mesh.geometry.boundsTree.closestPointToPoint(this._lastIntersection, target); if (target.distance < minDistance) { this._nearestPoint.copy(target.point); this._nearestPoint.applyMatrix4(mesh.matrixWorld); minDistance = target.distance; } } if (isFinite(minDistance)) { this.object.position.copy(this._nearestPoint); this.object.position.y += this.gazeLevel; } else { // NOTE: fallback if no bounding trees present on collision meshes this.object.position.copy(this._lastPosition); } } }This new code is from Verge3D preview that uses closestPointToPoint() method to push the camera back to the collision map. You’ll need to modify it to handle the “camera control object” instead.
