[FIXED]How make multiple "if" statements for choices (and other promblems)

[GoldenMagician]

Hi everybody! I want to ask, according to title. For example:

Code: Select all

menu:
        "I'm sure!" if $ smth1 >= 0 and if $ energy_reserve >= 2 and if $ smth2 = False:
          if $ some_effect1 = true:
           "Yes, i'm sure!"
          elif $ some_effect2 = true:
            $ energy_reserve -= 3
            "Yes, i'm sure!"
          elif $ some_effect2 = true:
            $ energy_reserve -= 1
            "Yes, i'm sure!"
          else:
            $ energy_reserve -= 2
            "Yes, i'm sure!"
        "No...":
           "No..."
 

Code: Select all

$ energy_reserve = 5
$ smth1 = 0
$ smth2 = False
$ some_effect1 = True
$ some_effect2 = True
$ some_effect3 = False

Where is mistakes here? When I click Start, there is error... D: (sorry for maybe bad english)
p.s. I know. First choice ask 2 energy in reserve, but some_effect2 minus 3 energy. I will be grateful, if you help with this too

Try

Code: Select all

menu:
        "I'm sure!" if smth1 >= 0 and energy_reserve >= 2 and smth2 == False:
          if some_effect1 == True:

The dollar sign is used at the beginning of a single-line python code.
Single equal sign is used for assigning, for comparison you need to use double equal sign.
Boolean values must start from capital letter.
You can set the values for you variables using default statement.

Code: Select all

# YOu need to use $ only to tell that next is Not a RenPy statement, but Python one.
# Conditions already expect Python expression, so you do not need it here
# The syntax is `if <condition>`; to join multiple conditions, use logical operators
"I'm sure!" if smth1 >= 0 and energy_reserve >= 2 and notsmth2:
    # `=` is "Make whatever is on left side to be thing on the right"
    # `==` is check for equality
    if some_effect1:
        "Yes, i'm sure!"
    # And it is True, not true
    elif some_effect2:
        $ energy_reserve -= 3
        "Yes, i'm sure!"
    # And you never need to compare to True (X == True ~ X)
    # Or False (X == False ~ not X)
    elif some_effect2:
        $ energy_reserve -= 1
        Yes, i'm sure!"
    else:
        $ energy_reserve -= 2
       "Yes, i'm sure!"
"No...":
    "No..."

Sorry, there is still problems. I'm write in the morning. I want to sleep...

Okay. This is code, where is minimum errors

Code: Select all

$ confident = False    
$ languor = True        
$ fearless = True       
$ uncertainty = False  
$ concentrated = False  
$ unfocused = False  
$ magic = 0               
$ strenght = 0            
$ eloquence = 0          
$ hacking = 0           
$ occult = 0             
$ dodge = 0             
$ interrogation = 0     
$ deception = 0        
$ mannerliness = 0     
$ psychology = 0        
$ trustful = 0           
$ energy_reserve = 5 

Code: Select all

label start:
menu:
    "I'm confident!" if $ trustful >= 0 and energy_reserve >= 2 and uncertainty == False:
        if fearless == true:
         "YES, I CONFIDENT!"
        elif languor == true:
         $ energy_reserve -= 3
         "YES, I CONFIDENT"
        elif confident == true:
         $ energy_reserve -= 1
         "YES, I CONFIDENT"
        else:
         $ energy_reserve -= 2
         "YES, I CONFIDENT"
    "Lol":
        "No..."
        
return

The only error is:

Code: Select all

Please read carefully what other people tell you, they've pointed out you don't have to put the $ sign in if statements, just use the variable names. So it should be:

Code: Select all

"I'm confident!" if trustful >= 0 and energy_reserve >= 2 and uncertainty == False: 

Also, in the lines below, it should be True (with a capital T) instead of true, and also as previously stated, if you're checking if a condition is True, you don't need to add == True, it can be simplified like this:

Code: Select all

if fearless:
    "YES, I CONFIDENT!"

Programming is all about attention to detail. This includes capitalization, if there is a $ or not.

I will also note...that you should be declaring all of your variables using default.

So...

Code: Select all

default confident = False    
default languor = True        
default fearless = True       
default uncertainty = False  
default concentrated = False  
default unfocused = False  
default magic = 0               
default strenght = 0            
default eloquence = 0          
default hacking = 0           
default occult = 0             
default dodge = 0             
default interrogation = 0     
default deception = 0        
default mannerliness = 0     
default psychology = 0        
default trustful = 0           
default energy_reserve = 5 

label start:
    "Whatever happens in your game..."

Pardon, but error still ocured. Maybe it helps, but for some reasons it didn't work. Same error

[trooper6]

Post your current code.

[GoldenMagician]

I make all variables with default.
Code, exactly after variables:

Code: Select all

label start:
menu:
    "I'm sure" if trustful >= 0 and energy_reserve >= 2 and  certainty == False:
        if fearless:
            "Yes, I'm sure!"
        elif languor:
            energy_reserve -= 3
            "Yes, I'm sure!"
        elif confident:
            energy_reserve -= 1
            "Yes, I'm sure!"
        else:
            energy_reserve -= 2
            "Yes, I'm sure!"
    "No...":
        "No..."
        
return

If i add "default" to variables EXACTLY in code and before, error:

I'm sorry, but errors were detected in your script. Please correct the
errors listed below, and try again.

default is a special word used in Renpy for creating variables, you only need to use it once, and it is only used to set variables to an initial, 'default' value, that means, not to add or substract, only to set. If you want to do those operations, in the script, that's when you use the $ sign.

Take a look at this code, it works, and it shows how everything in the script is supposed to be written and used.

Code: Select all

#First you create all your variables here with default
default confident = False    
default languor = True        
default fearless = False

default deception = 0        
default mannerliness = 0     
default psychology = 0        
default trustful = 0           
default energy_reserve = 5 

#The game starts here
label start:

#The game shows a menu
menu:
    "I'm sure" if trustful >= 0 and energy_reserve >= 2 and uncertainty == False: #Multiple conditions are checked
        if fearless:
            "Yes, I'm sure!"
        elif languor: 
            $ energy_reserve -= 3 #this substracts 3 to energy_reserve variable 
            "Yes, I'm sure!"
        elif confident:
            $ energy_reserve -= 1 #this substracts 1 
            "Yes, I'm sure!"
        else:
            $ energy_reserve -= 2 # 
            "Yes, I'm sure!"
    "No...":
        "No..."
