Hello guys !

Do any of you have examples with CreatePhysicsForce attracting and repelling sprites from some x,y coordinates ?

Also DeletePhysicsForce doesn't seem to work... any ideas how to use it ?

force = CreatePhysicsForce( 200, 200, 100, 0, 0, 0 )

DeletePhysicsForce(force) -> not working

Thanks !!

What version of AppGameKit are you using?

How is the DeletePhysicsForce command not working? Do you mean that the force still exists after you've deleted it?

Are you seeing this in only Windows or when testing on iOS or Android devices (either with Player or stand alone)?

Thanks for the help Ancient Lady !

Anyway this was my bad. DeletePhysicsForce is working.

I was creating several instances of CreatePhysicsForce within a FOR NEXT loop..like :

for i = 1 to 3
force = CreatePhysicsForce(.......)
next i
DeletePhysicsForce(force)


The above doesn't work as I am creating the force (assigned always to the variable force) 3 times. So I put the command beforce the FOR loop.

Nevertheless the DeletePhysicsCommand should work as well assuming only when i=3 the force variable is created again.

I dunno why AppGameKit doesn't have CreatePhysicsForce with a first parameter being the Index..like: CreatePhysicsForce(forceIndex,...) like other sprite parameters and others have.

Best Regards !

here is a good example of global forces. ignore a bit the code as I was trying different stuff but concentrate on the global forces.

press the left mouse button for forced to move away from the center.
