Question

我想自动缩放场景的大小，因为在GameScene.sks中，我只能为场景大小选择一些iPhone型号（iPhone 4s，iPhone SE，iPhone 6s和iPhone 6 Plus）。因此，我尝试自动缩放以自动支持所有模型。

这是我的SKScene中的代码：

class GameScene: SKScene {

override init(size: CGSize) {

    super.init(size: size)
}

required init?(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
}
.......

语法似乎是正确的，但是当我在模拟器中切换到GameScene时，应用程序将崩溃。我是一个初学者，所以可能是重写init函数使用错误。

Answer 1

import SpriteKit

class GameScene: SKScene {
    let backgroundNode = SKSpriteNode()

    override func didMove(to view: SKView) {
        backgroundNode.size = CGSize(width: displaySize.width, height: displaySize.height)
        backgroundNode.color = .red
        self.addChild(backgroundNode)
    }
}

Answer 2

我建议您在GameDViewController中的viewDidLoad（）方法中设置scaleMode，而不是手动设置每个大小。您可以将scaleMode设置为AspectFill / AspectFit / resizeFill等。这是示例代码。

import pandas as pd

df = pd.read_csv('test')
df2 = pd.read_csv('test.csv')
df2 = df2.rename(columns={'col1' : 'species'})
print(df)
#    species seq_names  value
# 0      dog     seq_C   0.67
# 1      cat     seq_F   1.40
# 2      cat     seq_E   0.40
# 3  dolphin     seq_F   0.70
# 4  dolphin     seq_A   1.90
# 5     frog     seq_A   0.80
# 6     frog     seq_B   0.40

print(df2)
#    group_number  species
# 0             1      cat
# 1             1      dog
# 2             2  dolphin
# 3             2     frog

#   We now don't immediatly drop the duplicates, we want to save the merge before.
#   Doing this, we're able to keep the seq_names associated with their group_number.
ndf = df.merge(df2, on='species')\
        .sort_values(by='value', ascending=False)

#   I make a copy so that I get a whole new DataFrame.
#   If I didn't. Changes made to seq_groups would have affected the original.
seq_groups_df = ndf[['seq_names', 'group_number']].copy()
seq_groups_df = seq_groups_df.rename(columns={'seq_names' : 'sp_seq_names'})
print(seq_groups_df)
#   seq_names  group_number
# 4     seq_A             2
# 1     seq_F             1
# 5     seq_A             2
# 3     seq_F             2
# 0     seq_C             1
# 2     seq_E             1
# 6     seq_B             2

ndf = ndf.drop_duplicates(subset='seq_names', keep='first')

#   Either select the interesting columns.
ndf = ndf[['group_number', 'species']]
ndf = ndf.rename(columns={'species' : 'sp_seq_names'})

print(ndf)
#    group_number sp_seq_names
# 4             2      dolphin
# 1             1          cat
# 0             1          dog
# 2             1          cat
# 6             2         frog


result_df = ndf.append(seq_groups_df).reset_index(drop=True)
print(result_df)
#     group_number sp_seq_names
# 0              2      dolphin
# 1              1          cat
# 2              1          dog
# 3              1          cat
# 4              2         frog
# 5              2        seq_A
# 6              1        seq_F
# 7              2        seq_A
# 8              2        seq_F
# 9              1        seq_C
# 10             1        seq_E
# 11             2        seq_B
