我在 Godot 中创建了一个“加法心算计算器”,用户在点击“on_Button_pressed”按钮时会看到一个新问题,总和存储在“global var c”中,然后通过“Lineedit”访问输入并存储在“var d”中。但是,当传递“var c”以与“Lineedit”中的“var d”进行比较时,它传递了一个“Null”值。如何在两个函数之间传递值。
extends Panel
# global variables
var a = " "
var b = " "
var c = " "
var d = " "
func _ready():
pass
#Generate Random number and store sum in "var c"
func _on_Button_pressed():
randomize()
var a = floor (rand_range(1,100))
var b = floor (rand_range(1,100))
var c = a+b
print (a)
print (b)
print ("c = "+ str(c))
get_node("RichTextLabel").set_text(str(a)+"+"+str(b)+"=")
#User_input
func _on_LineEdit_text_entered( text ):
d = get_node("LineEdit").text
#pass sum "var c" for comparison with user_input "var d"
print(c)<-- NUll value being passed.
#Accesing value via node method
# var e = get_node("Panel").get("c").to_float()<-- Error-"Panel node doesn't exist"
# print(e)
#convert d to float
var f = d.to_float()
print(f)
#Compare sum with user_input
# if f == c:
# get_node("RichTextLabel").set_text("Right Answer")
# else:
# get_node("RichTextLabel").set_text("Wrong Answer")
