score;

返回：

Real（实数）

描述

This built in instance variable is used to hold a numeric value for the object score (note that this is not necessarily always the case - just because it's called "score" doesn't mean it has to be used for the scoring... it can hold any real or integer value you wish for your game).

例如：

if place_meeting(x, y, obj_Bullet)
   {
   score += 10;
   instance_destroy();
   }

The above code checks the current instance to see if there is a collision with the instance of the object indexed in "obj_Bullet", and if there is, it adds 10 to the score and then destroys itself.
