Question
I did some re-designing of my current game, in order to simplify things. Made some progress, but I hit another roadblock. I don’t see the button move on the world map, despite having code lines making a tween. Additionally, the “if” statement under the _on_timer_timeout()" method doesn’t seem to trigger. I do sometimes see the cargo amount be subtracted in the output, but not always. I suppose it is possible I am not seeing the button moving on screen because of the possibility the “create_airship_icon” is not being triggered because of this. I have the “World_Map” image in z-index 0, with the “TileMapLayer” z-index as 1. Below is a screenshot of my node tree, as well as my code, any feedback that would help solve this would be greatly appreciated:
Code for World_Map node:
extends Node2D
var balance: int
#Dictionary that stores city name and its tile coordinates
#City name as key, then city location, then population, then cargo to be delivered, then airship count
var cities = {
"Los Angeles": [Vector2(78, 165), 1000000, 1000000, 1],
"San Fransisco": [Vector2(73, 161), 1000000, 0, 0],
"San Diego": [Vector2(80, 166), 1000000, 0, 0],
"Chicago": [Vector2(123, 152), 1000000, 0, 0],
"Houston": [Vector2(113, 169), 1000000, 0, 0],
"San Antonio": [Vector2(108, 170), 1000000, 0, 0],
"Dallas": [Vector2(110, 166), 1000000, 0, 0],
"New York": [Vector2(142, 156), 1000000, 0, 0],
"Seattle": [Vector2(73, 143), 1000000, 0, 0],
"Vancouver": [Vector2(71, 139), 1000000, 0, 0],
"Anchorage": [Vector2(31, 113), 1000000, 0, 0]
}
var active_cities = [
"Los Angeles",
"San Fransisco",
"San Diego"
