Instance Variable

Hi.

I've used 'instance variables' a few times, but I still don't quite understand it.

Can I use instance variables in this situation to re-use the object 'Sensor_1:'

by giving it the variable instance property?

I'd like the sensor object to do different stuff depending on which instance Player collides with. How do I check which instance of Sensor_1 Player is in collision with?

Thank you

Instance variables are used when you want a piece of data to be unique to an instance. In other words, if you have 10 sensors with an instance variable called "range" (for example), each sensor can have a different value for "range".

When a player object collides with a sensor, C2 will pick the specific instance(s) of sensor that collided with player. If you then access the sensor's instance variable, it will be specific to that sensor.

Thank you.

So, making many new objects called Sensor_1 Sensor_2 etc is ok?

I have a kind of Construct-Anxiety with this kind of thing. I'm always worried that adding too many objects will 'slow it down'. (Am I just being supersitious?)
