What's the mean of the Point-value?

I relly want to know what's the use of it.

I think it is how many points killing the unit will give you (to be used in the statistics when the game ends), but I am not sure at all.

I had tried it,but it isn't.

It means nothing. People just use it because you can get it on triggers, so they use it for many different things depending on the map (for example a map's trigger may need to know if a unit is a robot, they use 1 for point value of all units to be considered robots and 0 for the other.

Then a trigger compares point value of unit to robot.


And stuff like that

And it is commonly used for sell values of towers in tower defense maps.

generic value used across all units of that type and is not changeable in game
