How to dispose of blender object? SOLVED

giorfasolini · April 21, 2017

Hi Forum,

First of all, i tried to create a snake game for my project, however i have encountered some difficulties. I can't make the apple dissapear upon contact / collision with the snake.
I can make the object dissapear normally if its just mesh from babylon ( sphere, box, etc ) . However, when i tried to do the same to imported blender object, it doesnt work, Any ideas?

Any Help given is greatly appreciated. Thank you

here's my code :

P.S : i tried to upload it to playground, but it seems not working, as my snake and apple are on different file, and i dont know how to upload them in playground.

There is no real difference between an imported object over one made using MeshBuilder. The most likely problem is either you assigned the wrong mesh to apple ( use scene.getMeshByName('blendername') not meshes[0]), or your code is not getting called. Add a console.log message just before the dispose to verify it is getting called.

I don't think this line of code will work:

BABYLON.SceneLoader.ImportMesh("","Finalproject/", "apple1.obj", scene, function (meshes)

For importing .obj files see this thread

cheers, gryff :

@gryff

Thank you for your feedback, I have finally found my source of mistake, which is i forgot to join the object in blender using CTRL + J
Sorry for late reply.
cheers
