I’m making a game with a grid with a player that has grid-based movement. An aiming reticle will show when i press a certain key and then hides it when i release that key. The player is in the grid like i want it to; but the reticle isn’t, can you tell me how to attach it to the grid please here’s the code.
Grid:
extends TileMap
enum ENTITY_TYPE {PLAYER, OBJECT, COLLECTIBLE}
var tile_size = get_cell_size()
var half_tile_size = tile_size / 2
var grid_size = Vector2(16, 8)
var grid = []
onready var player = preload("res://Scenes/Entities/Player.tscn")
func _ready():
for x in range(grid_size.x):
grid.append([])
for y in range(grid_size.y):
grid[x].append(null)
#Spawn Player
var new_player = player.instance()
new_player.set_pos(map_to_world(Vector2( 4, 4)) + half_tile_size)
add_child(new_player)
var position = []
for x in range(5):
var placed = false
while not placed:
var grid_pos = Vector2(randi() % int(grid_size.x), randi() % int(grid_size.y))
if not grid[grid_pos.x][grid_pos.y]:
if not grid_pos in position:
position.append(grid_pos)
placed = true
func get_cell_content(pos = Vector2()):
return grid[pos.x][pos.y]
func is_cell_vacent(pos = Vector2(), direction = Vector2()):
var grid_pos = world_to_map(pos) + direction
if grid_pos.x < grid_size.x and grid_pos.x >= 0:
if grid_pos.y < grid_size.y and grid_pos.y >= 0:
return true if grid[grid_pos.x][grid_pos.y] == null else false
return false
func update_child_pos(new_pos, direction, type):
var grid_pos = world_to_map(new_pos)
print(grid_pos)
grid[grid_pos.x][grid_pos.y] = null
var new_grid_pos = grid_pos + direction
grid[new_grid_pos.x][new_grid_pos.y] = type
var target_pos = map_to_world(new_grid_pos) + half_tile_size
return target_pos
Grid Visualizer:
extends Node2D
onready var Grid = get_parent()
func _ready():
set_opacity(0.2)
func _draw():
var LINE_COLOR = Color(0, 0, 0)
var LINE_WIDTH = 2
var window_size = OS.get_window_size()
for x in range(Grid.grid_size.x + 1):
var col_pos = x * Grid.tile_size.x
var limit = Grid.grid_size.y * Grid.tile_size.y
draw_line(Vector2(col_pos, 0), Vector2(col_pos, limit), LINE_COLOR, LINE_WIDTH)
for y in range(Grid.grid_size.y + 1):
var row_pos = y * Grid.tile_size.y
var limit = Grid.grid_size.x * Grid.tile_size.x
draw_line(Vector2(0, row_pos), Vector2(limit, row_pos), LINE_COLOR, LINE_WIDTH)
