Unzip the Objects.zip over top or into your 3drad Objects folder.
Save and rename the Chopper Work.3dr file without the .txt extension into your 3drad Projects folder.
I would suggest keeping the ridgidbodies as i've created them and just add skinmesh's on top for looks and hide the rigidbody in their popup data boxs. UnCheck "[ ] Display Geometry".
But you certainly can change and edit the project anyway you like, but that will / may change the way the physics work, requiring even more editing in the script and object properties.
Also be sure to link the rigidbodies and skinmesh to each other so they follow each other once added.
It's not perfect, i didn't add any option to move sideways and the controls are setup for keyinput...
You can define joysticks or game-pad controls / buttons if you like for each or part of the key inputs, but the proportional controls wont work as you mite expect, as said its just a basic helicopter project, and a good start to something more realistic if needed. The buttons will work fine though.
No credit is required, unless you make a million with this project, then i want $100K one time payment.
Thanks, and I hope others may find it useful. I plan to use it to make a GTA style game which I wanted it to be free. But If the game does gets sold, and reaches a million (unlikely), agreed, you will get the share. I credit each and every contributor to the games I develop.
