Hey folks, I’m working on a mock up for a game, specifically on the enemy tracking system. I’m aiming for a Zelda-esque feel, where the player tracks to the nearest enemy while a certain button is held, but can roam free otherwise. I’ve gotten a “track to enemy” script (that I found on the forums) working such that when i press Shift it will track to the enemy, however the only way to clear that tracking is to have it track to a different enemy.
So, could anyone help me out with a way to clear the object being tracked to when Shift is not being pressed? I feel like it should be a simple affair (else: track_ob.setObject(none)?) but I only know the bare bones of python so I’m drawing a blank. I can post my .blend if that would help, but unfortunately I can’t remember who wrote the script. Thank you for your time!
Woah. Although this looks amazing, I tried to implement it for almost an hour and couldn’t get anything. It’s definitely over my head, and I’m using 2.49 if it makes a difference. Regardless, I already have tracking working, I just need a way to clear the tracking when Shift isn’t being pressed.
I really appreciate your help. However, like I said, I’m using 2.49, (every newer version has major GUI bugs for me) so that file didn’t work. I’m really just looking for a way to make my player object track to nothing after it tracks to an object.
So, here’s the file, and I need the tracking only to last as long as Shift is being held down, and once it’s let go, the object is free to turn on it’s own.
Here’s 2 scripts that track to the nearest object with property:enemy, useful for homing missles and whatever else you can come up with.
1.Give each enemy a property:enemy
2.Give the tracking object these logic bricks:
Always—>python:trackToClosest—>EditObject:TrackTo, named “trackTo”
--------------------------------------------------->Any Positive-Y motion, set to Local
3. Use what ever method you prefer for creating projectiles and damage. I’m currently using a missle with no collision and a ray that checks in front for prop:enemy. If the ray is positive, it ends the missle object and inflicts damage on the target.
Create a list of all the enemies within range 100 of the player.
import GameLogic as g
cont = g.getCurrentController()
own = cont.getOwner()
scene = g.getCurrentScene()
objList = scene.getObjectList()
#create a list of all enemies within range 100 #change this number to best fit your game area
g.enemyList=
for i in range(0,len(objList)):
obj = objList[i]
if hasattr(obj,“enemy”):
if own.getDistanceTo(obj) <100:
g.enemyList.append((obj.name))
2. Create a list of distances to enemies, relative to the script owner, then sorts the list. enemyRanges[0] is the enemy with the smallest distance from the object.
import GameLogic as g
cont = g.getCurrentController()
own = cont.getOwner()
objList = g.getCurrentScene().getObjectList()
#check to see if there are any enemies within range
if len(g.enemyList) > 0:
#create a list of the enemies within range and their distances #each list item has 2 parts: (distance, OBname)
enemyRanges =
for i in range(0,len(g.enemyList)):
enemy = objList[g.enemyList[i]]
dist = own.getDistanceTo(enemy)
enemyRanges.append((dist,enemy.name))
#sort the list. the first object will be the one with the shortest distance
enemyRanges.sort()
#get the second item (OBname) of the first list item, then strips ‘OB’ from the string
nearestEnemy = enemyRanges[0][1][2:]
#set your object to track to the nearestEnemy #the name returned is “OBenemy”, but the trackTo actuator just needs “enemy” #the [2:] removes the “OB” from the object name for proper tracking
track.setObject(nearestEnemy)
#activate the actuators
g.addActiveActuator(track,1)
g.addActiveActuator(motion,1)
else: #if there are no enemies, activate only the motion actuator
g.addActiveActuator(track,0)
g.addActiveActuator(motion,1)
I had actually found that one on my own, and like I said, I already have the tracking script. I managed to fix it on my own using logic states, but thanks for your time.
