Hello.

I get this error when trying to run the program:

Runtime Error 7801 - Vector does not exist at line 124.

I am using this code:

y = camera position y()+10

if keystate(57)
position camera 1,y
endif

if y
position camera 1,y-10
endif

The code in bold are line 124.

Anybody know what the problem may be? Will placing a vector fix it? If so, whats the code for it? Or give me the section in the command index in the help contents if you can.

Thanks

When you use a single value after the camera number in the POSITION CAMERA command, you are instructing DBPro to use the vector version of the command.

What I think you want is:


You'll need to change the other command a few lines earlier in a similar way too - remember, a position has 3 points, not 1
