I am attempting to create a pivot for some smoke that needs to be attached to a funnel. For testing purposes I have just attached a funnel to a car. I am using the dBodyGetPositionX, Y & Z respectively however I am only able to return integers. I require more precision in order to place my smoke dynamically on top of the funnel.

Can anyone please tell me if it is possible to return a float from the following dBodyGetPosition{X,Y,Z} argument ?

funnelx=Float dBodyGetPositionX(Car)
funnely=dBodyGetPositionY(Car)
funnelz=dBodyGetPositionZ(Car)

Thanks in advance - BP.

I seem to have found a workaround which ties my smoke to my funnel:

Not entirely sure where that function comes from, but you can get a function to return a float by sticking a hash (#) at the end of the function declaration, i.e.:

funnelx=dBodyGetPositionX(Car)

Function dBodyGetPositionX#(entity)
   ;whatever the function is
   Return value#
End Function

Note that further modification may be required if the existing function only operates with integers.

In addition to what gfk already wrote, if the first line of this is the first occurance (ie a declaration) you need a # on the end of that too.

ie;
funnelx#=dBodyGetPositionX(Car)

Although not nessecary i prefer to try and remember to use %#$ for int/float/string declarations and in complex formulas. Also i try and use them throughout, especially # and $, that way i know exactly what they are and because blitz3d does not have stricts(shame!) it helps stop math errors.

eg:
funnelx=dBodyGetPositionX(Car)
funnelx#=funnelx#+10

would throw an error telling me i screwed up on the declaration.
