Ghost Sensor

Hey everyone,

I would like to have a ghost object, that other physics objects can pass through, act as a sensor. I can't figure out a way to do this without making the object an actor.

Thank you!!!

Check SIO2sensor

Right, but the sensor only gets triggered in the event of a collision, correct? And if the object is a ghost, it doesn't seem to register when another object passes through it

The property ghost (as I explain in the tutorial06 video) is mainly used for collision maps... that will override the drawing but still keep a collision object... So it means that if its set to ghost and have physic properties ON, the object will collide with it...

I don't think that's what you are looking for...

Thanks SIO2

Yea, that's not quite what I'm looking for. I don't want the object to have physics properties; I want the object to act as a sort of invisible sensor that can detect when an object passes through. Does that make sense?

Hummm maybe give me more informations about what you are trying to achieve so I can check what is more suitable for your situation...


Cheers

I would like to have a plane that is invisible, and that doesn't collide with objects - any object can pass through it. However, I would like to be able to detect when an object has passed through it.

Im not really sure exactly what you want to do but maybe SIO2sensordistance would do the trick... If the object distance is <= than the object radius it means that is pretty near that plane

I will try that. A million thanks sio2!

There's also this method that is testing a sphere within a plane to check if its in front, intersecting or behind... Im personally using similar method for the culling method of SIO2...
