This project’s orcHitTest function demonstrates using a spherecast to make an orc model jump when the orc collides with something near its feet.
Update: previous file didn’t work. This one does. 
I got an error:
Main:161: bad argument #1 to 'mul' (`vec3' expected)
stack traceback:
[C]: in metamethod 'mul'
Main:161: in function 'orcHitTest'
Main:148: in function 'draw'
Was that with the updated version? The first one I posted did have that error, I thought I corrected it in the update.
Thanks! The new one is OK!
@UberGoober - I’m getting errors for Craft but I’m assuming that your demo is Codea V3 and I’m on 4.
@Bri_G You can easily switch between 3.x and 4.x depending on what version of code you want to run.
@dave1707 tried with and without the require legacy but still fires up errors. It also mentions craft as unrecognized. I have made sure dependencies for camera and blocks were activated. Could there be clashes in the dependency code, I’ll check that.
@Bri_G When I want to run either 3.x or 4.x code, I start Codea and tap on the gear icon (top right of screen) and then select either 3.x or 4.x from the Runtime depending on what I want to run. I’m not sure what the require legacy thing is supposed to do.
@dave1707 - thanks for that, hadn’t even noticed that - it will make it much simpler for me now.
