Hello,
I am learning UPBGE with python. I have created this demo project in UPBGE using Python. But I don’t know where the problem is in my code and why it’s not working
code:
import bge
from bge import logic, events
from mathutils import Vector
tc = logic.keyboard.inputs
mc = logic.mouse.inputs
def start(cont):
own = cont.owner
own["armature"] = [obj for obj in own.children if "armature" in obj] [0]
own["armature"].playAction("Ani_1", 0,258,)# Player idle Animation
def update(cont):
scene = bge.logic.getCurrentScene()
cont = bge.logic.getCurrentController()
own = cont.owner
w = cont.sensors["W"] # keyboard sensor
propfire = cont.sensors["Fire"] # property sensor. property < 40
propreload = cont.sensors["Reload"] # property sensor. property > 40
propreload0 = cont.actuators['Property'] # property actuator. property 'assign' 0
if tc[events.WKEY].values[-1]: # keyboard, W_KEY
own["armature"].playAction("Ani_1", 259,279,) # Player Movement Animation
if propfire.positive: # property sensor. property < 40
if mc[events.LEFTMOUSE].values[-1]: # LEFT_MOUSE_Button
for ob in scene.objects:
if "ammo" in ob: # object Property
ammo = own["ammo"]
own["ammo"] += 1
print(ammo)
own["armature"].playAction("Ani_1", 280,316,) # Player Fire Animation
else:
own["armature"].playAction("Ani_1", 0,258,)# Player idle Animation
if tc[events.RKEY].values[-1]:# keyboard, R_KEY,
own["armature"].playAction("Ani_1", 317,353,)# Player Reload Animation
frame = own["armature"].getActionFrame() # Reload Animation Frame Count
print(int(frame))
if frame >= 352:
cont.activate(propreload0)# property actuator. property 'assign' 0
else:
cont.deactivate(propreload0)# property actuator. property 'assign' 0
elif propreload.positive: # property sensor. property > 40
own["armature"].playAction("Ani_1", 317,353,) # Player Reload Animation
frame = own["armature"].getActionFrame() # Reload Animation Frame Count
print(int(frame))
if frame >= 352:
cont.activate(propreload0)# property actuator. property 'assign' 0
else:
cont.deactivate(propreload0)# property actuator. property 'assign' 0
else:
own["armature"].playAction("Ani_1", 0,258,) # Player idle Animation
Your reloading animation works fine for me, as does the idle animation.
The walking and firing animation does not for me, however. I think you need to setup some action priorities. Otherwise your animations are playing the same action simultaneously, at different frames.
Can you fix this for me:
I have been working on this for 3 days. i am learning python and i dont know where i am having an issue? can you please fix this for me and tell me the exact issue? TIA
See if it has anything to do with the animation itself : difference of length, number of channels, same channels…
Since there’s a “stopAction” function maybe python doesn’t like that you stop an action by playing another one.
Check out that “priority” option with that “playAction” function. With that you can over-write with no problem. But I don’t know if the underdog will resume if it is longer . You have to investigate deeply and precisely the bhavior behind
Interesting fact i noticed : replaying the same animation but at different Start or End is ignored by the Action Actuator since there’s no animation replacement since there’s no change (coz same name) … maybe python has some zone of confusion there too? … I don’t know.
I guess you are spamming this code at each logic tic (didnt check) … that architecture is ok for computing realtime math , but dealing a complex action system with that is a receipt of a disaster . It’s a bad habit that we are seeing around for years … the game architecture will end up being a total garbage and impossible to debug once the game is becoming complex. Launch a piece of code at a precise event only .
→ So … if you see basic setup running at 20-30 fps … warning warning … this just cannot be!
Careful in general with property sensors( frame) that are the result of your direct actions(buttons)
maybe you don’t know this, but you can also use python to change the parameters of the logic bricks … and since the bricks run faster (coz C/C++ behind) than python code … If you master the comprehension of bricks + some clean python code , your get the best of 2 worlds. With hybrid solution, you will get everything done with 2 sensors, 1 action actuator and 1 python control of 10 lines of code…
…whilst using either 100% bricks or 100% python and you end up either with a building or a bible.
Pure python is good for stuff that doesn’t exist with bricks like AI or some matrix computations, but for fast-running things like actions or any sensors, bricks are your friends .
this happen because you dont blendin you animations in script - you animation always play how use only first layer - armature.playAction(“Reload_Gun”, 0, 100, blendin=5, layer=20), armature.playAction(“Player_Walk”, 0, 50, blendin=5, layer=1) - use more blendin, layers and setup for mixing animation in game or looking API - for understand how mixing you animation
