我目前正在编写一个小脚本,在Autodesk Maya中自动创建一个类似起重机的装备,用户可以通过用户界面选择关节的数量。在
我的问题是如何获取用户的整数输入并将其用作“jointAmount”的变量值?在
我还想知道如何才能调用函数(AutoCraneRig)从UI实际运行脚本。我有一个“应用”按钮,但我不确定如何连接到我的功能。在
我也看过类似的帖子,但我觉得所展示的解决方案对我来说有点难以理解,或者我无法将所显示的内容与我自己的问题联系起来。在
如果有什么不清楚的地方或需要我提供更多信息,请随时打电话给我。在
Here is what my current UI look like
import maya.cmds as cmds
import pymel.core as pm
def jntctrl():
number = pm.intField(jnt, q=1, v=1)
print(number)
if pm.window("stuff", exists = True):
pm.deleteUI("stuff")
pm.window("stuff", t = "Crane Rig Generator", w=400, h=200)
pm.columnLayout(adj = True)
pm.text(label="Joint Amount:")
jnt = pm.intField(changeCommand = 'jntctrl()')
pm.button(label="Create Crane")
pm.showWindow()
#Defining how many joints the user want to have for their crane rig
jointAmmount = 5
#Defining how many controllers the user want to have to orient the crane.
#May not exceed the joint amount
controllerAmount = 5
def autoCraneRig():
#Creating the joints
for i in range(jointAmmount):
pm.joint()
pm.move(0, i, 0)
#Creating the controllers
for i in range(controllerAmount):
pm.circle()
pm.rotate (0,90,0)
pm.makeIdentity (apply= True)
#Creating the groups
for i in range(controllerAmount):
pm.group()
#Somehow one of the nurbs get parented to a group when running the script, here i select both the groups and then unparent them.
pm.select("group*", "nurbsCircle*")
pm.parent(world = True)
#Creating lists/dictionaries for the groups
#Since I wanted to parent my objects by their number I had to put all objects in lists/dictionries to get access.
groups = pm.ls('group*')
nbs = [int(n.split('group')[-1]) for n in groups]
groupDic = dict(zip(nbs, groups))
#Create a list/dictionary for the joints
joint = pm.ls('joint*', type='joint')
nbs = [int(n.split('joint')[-1]) for n in joint]
jointDic = dict(zip(nbs, joint))
common = list(set(groupDic.keys())&set(jointDic.keys()))
#Parenting the groups to the joints
for i in common:
pm.parent(groupDic[i], jointDic[i])
#Reseting the transformations of the groups and then unparenting them to still have the transformation data of the joints
pm.select("group*")
pm.makeIdentity()
pm.parent(world = True)
#Creating a list/dictionary for the nurbs aswell that will be parented to the groups in numeric order
nurbs_sh = pm.ls('nurbsCircle*', type='nurbsCurve')
#I had to get the transformation information from the nurbs before parenting them with anything would work(took a long time to get it right).
nurbs_tr = pm.listRelatives(nurbs_sh, p=1)
nbs = [int(n.split('nurbsCircle')[-1]) for n in nurbs_tr]
curveDic = dict(zip(nbs, nurbs_tr))
common = list(set(groupDic.keys())&set(curveDic.keys()))
#Parent the nurbs to the groups
for i in common:
pm.parent(curveDic[i], groupDic[i])
#Select the nurbs and reset transformations and then freeze transform
pm.select("nurbsCircle*")
pm.makeIdentity()
#Orient constrain the controllers/nurbs to the joints
for i in common:
pm.orientConstraint(curveDic[i], jointDic[i])
#Parent the 2nd group with the first controller. Do this for the whole hierarchy.
for i in common:
pm.parent(groupDic[i+1], curveDic[i])
#I'm getting keyError after I put the "+1" in my groupDic and I don't know why, although it still works, I guess.

下面是一个示例,说明如何在单击按钮时调用特定的函数/命令,以及如何获取int字段的值。关键在于命名字段,以便以后可以引用UI控件。在
