Project help

[Binchotype]

Hi, I'm doing a project for one of my electronic classes in college and I've chosen to build kind of an arcade shooter using IR, but I'm a little stuck on one end of the project. On my recieving i want three IR recievers to be triggered when hit then be worth a certain value, say one target is 2 points, and one target is worth 5 points, but my problem is I'm not sure how implement this to where when each taret is triggered it adds the points together to show on an LED display. I was wondering if someone could point me in a general direction in how to go about doing this, so thanks in advance.

Its simple I think.
U just make ir emitting led as shooter.and the target as ir sensor.but be careful at placing the sensors.if it is outside the insulating surface it will be wrongly triggered.
Nextly,
Connect ir reciever output(configure the output such that the output is high when it senses the ir from the gun)to counter(separate counters to separate points target).becarefull at summing and interfacing it to LED.
