Can't load objects

Hi people. I am having a major problem here in getting my file requester to work. When I run the code and press L to load an object I get the error "Variable must be a type" for some reason. It highlights the code:

If KeyDown(200) Then MoveEntity m\entity,0,0,.1

As being the offending code. For some reason though.
I can't figure this one out its driving me insane :(

So the thing is, it shouldn't be flagging me an error to begin with as I haven't even had the chance to load a file for it to check in the first place :(

Here is my code. I would be very grateful if someone can help me out here.

Thanks for any help guys :)

In your check_move() function the 'm' does not exist yet. You have to pass the type directly to the function like this "function check_move(m.mesh)", alternatively you have to make the type instance holding your entity global.

Hi Matty :) Thanks a million. That sorted out the problem :)

Now i'm presented with a new problem. When I press L to load an object, I get the error message, "Entity does not exist" and it highlights:

FitMesh m\entity,m\x,m\y,m\z,0.9,0.9,0.9

As being the offending code. Any ideas?


Thanks again for your help. Very much appriciated :)

Hmmm. Actually, its quite difficult to fully explain my problem so I have included a link to a zip file below. This contains everything for the code to run.

Just make sure to have either a 3ds or B3d object to test it out :)

Here is the file:

EDIT: Sorry I am having a problem with getting a link to my file :( I have this code enclosed in the [a] and [/a] but the link doesn't seem to work even though I know the location to the file is correct :( I'll see if I can fix it somehow.

The code in [a] and [/a]
