Hi, apologize if looking in the forum I have already missed the answer to the question I’m about to ask Someone can give me a concrete example of how to use Vector3 Unproject, to convert screen xy coordinates into world coordinates? thank you in advance for any help!

Hey and welcome back! here is how to use it: var vector= BABYLON.Vector3.Unproject( mousePosition, engine.getRenderWidth(), engine.getRenderHeight(), BABYLON.Matrix.Identity(), scene.getViewMatrix(…

yep :slight_smile: mousePosition is your pointerX/Y thingy

Hi and thanks for a great product. I would like to add - make sure your (input) mousePosition.z is set to 1 to get the expected results I have been lurking for a while - writing a racing game … about 8 weeks in - thought I would try and make a positive contribution

Hey and welcome!! Please share your game when you want :slight_smile:

Will do … although it is nowhere near as far along as the Need for Speed demo… It’s a top down, racer with custom physics (mass spring system)… I am focussing on high frame rates and smooth gameplay, with analogue input (gyro, accelerometers, mouse) for a nice driving feel… cross platform obviously…

Hello everyone, I am (I think) in the exact same issue. I need to add a sphere where the user clicks. I tried the following option : var ballPos = BABYLON.Vector3.Unproject( new BABYLON.Vector3(scene.pointerX,scene.pointerY,1), engine.getRenderWidth(), engine.getRenderHeight(), BABYLON.Matri…

OK I think I have found the solution here : Scene.pointer to Vector3

Having same trouble here. Any help appreciated.
