what wrong with this code?

Game Engine Game Engine Support and Discussion
#1

Hi,
please get this blend file and run the game engine please. All I do in 2.49b.
Simple use WASD to control the cube, press “q” to add a shooting Cone and “e” to remove it. Better if still use Top Ortho view to see the effect clearly:)

test_pickup_sample.blend (142 KB)

This is what I want. For simple condition like this, it work well enough. But how I wonder if I use many - many object as the cone? I think it will be troublesome to do and the logic for the Empty “mount_01” will so messy…

so,
to simplify the process I try search on the web and at tutorialsforblender3d I found a sample command using object.setParent. I copy the code as is and get this blend file. But why the game didn’t run as I want? I mean as the first file that didn’t use python.

test_pickup.blend (147 KB)

someone can help me?
Thank u very much for the response.:slight_smile:

you define “mount” but use then “mount_01”, thats wrong.
You can add Objects by GameLogic.getCurrentScene().addObject(“Player”, cont.owner)

#3

thax for help sevi, but it still didnt’work. this the file that i corrected according to your suggest. I commented line that i try to corrected.
test_pickup_corrected.blend (147 KB)

in console window it said
File “mount”, line 7, in <module>
"Key Error : “GList[key] '‘Cone’'key not in list”
etc…

where my wrong? :no:

Firstly it says that there is not an object called Cone in the scene.
Secondly, you need to use OB in front of object names in 2.4
corrected code

cont = GameLogic.getCurrentController()
scene = GameLogic.getCurrentScene()

own  = cont.owner
objList = scene.objects

con    = objList["OBCone"]
mount = objList["OBmount_01"]

pick = cont.sensors["sensPick"]
rmov = cont.sensors["sensRemove"]
actPick = cont.actuators["actPick"]
actRemove = cont.actuators["actRemove"]
actPick.object = "Cone"

print objList;

if pick.positive == True :
	if own["pick"] == False :
		GameLogic.getCurrentScene().addObject("Cone",own) # &lt;= change this part
		con.setParent(mount, 0, 1) # &lt;== corrected this
		own["pick"] == True	
	
if rmov.positive == True :
	if own["pick"] == True :
		cont.activate(rmov)
		own["pick"] == False

Hei agoose77,

it still didn’t work… in console it said

Traceback (most recent call last):
file “mount”, line 7, in <module>
KeyError: “CList[key]: ’ ’ OBCone’ ’ key not in list”

the cone object already there in layer2 (off)
i use blender 2.49b for this file…
if the code work, when in the GE i hit “q” it must adding the shooting cone as child of the cube as in file “test_pickup_sample.blend” did…
still confuse…
sorry…

Threads like this are what’s wrong with this board.
Use some critical thinking skills to attempt a solution on your own. Look at line 7 in your file and find out why that cone isn’t there.

If the object isn’t on the same layer as what you are viewing, it isn’t in the scene object list.

#7

If the object isn’t in scene.objects, is it in scene.objectsInactive? Sorry if this doesn’t help, but 2.5x is far more friendly for scripting.

Edit:

Forget the new ui, the main improvement for non-artists in 2.5x is the api changes. This is the main reason that bge users moved to 2.5x when is was still deep in alpha. Unbelieveable control at your fingertips. I personally could never go back to 2.4x not because of the ui, but because of the Python api.

Hope you sort it out. :slight_smile:
