非常简单的小地图包源码

@script ExecuteInEditMode()
// radar! by PsychicParrot, adapted from a Blitz3d script found in the public domain online somewhere ..

//Modified by Dastardly Banana to add radar size configuration, different colors for enemies in different states (patrolling or chasing), ability to move radar to either one of 9 preset locations or to custom location.

//some lines are particular to our AI script, you will need to change "EnemyAINew" to the name of your AI script, and change "isChasing" to the boolean within that AI script that is true when the enemy is active/can see the player/is chasing the player.

有C#版吗

brutty 发表于 2013-3-31 16:36

好像的确很简单的啊
