合并多个精灵节点？
合并多个精灵节点？
提问于 2022-10-19 07:57:40
例如，假设我有2个sprite节点(但也可能超过2个)，如下所示：
每个人都有各自的形象
我想要的是将它们组合起来，创建一个具有单个映像的新sprite节点(在工具模式下)。
就像这样：
也许使用Image是可能的？(无疑涉及计算)
或者使用VisualServer的东西

我找到了解决办法
tool
extends Sprite
export (Vector2) var img_size setget set_img_size
export (String) var img_path = "res://MergeImg.png"
export (bool) var generate_img = false setget set_generate_img
var ep_filesystem=EditorPlugin.new().get_editor_interface().get_resource_filesystem()
func set_img_size(new_val):
img_size=new_val
update()
func _draw():
draw_rect(Rect2(0,0,img_size.x,img_size.y), Color(0,200,0), false, 1.0)
func set_generate_img(new_val):
if(not new_val):
return
var screenshot_viewport=Viewport.new()
screenshot_viewport.size=img_size
screenshot_viewport.hdr=false
screenshot_viewport.transparent_bg=true
screenshot_viewport.render_target_v_flip=true
for child in get_children():
remove_child(child)
screenshot_viewport.add_child(child)
add_child(screenshot_viewport)
screenshot_viewport.set_update_mode(Viewport.UPDATE_ONCE)
yield(VisualServer,"frame_post_draw")
var mergeImg=screenshot_viewport.get_texture().get_data()
mergeImg.save_png(img_path)
for child in screenshot_viewport.get_children():
screenshot_viewport.remove_child(child)
add_child(child)
child.set_owner(get_tree().get_edited_scene_root())
screenshot_viewport.queue_free()
ep_filesystem.scan()
yield(ep_filesystem,"filesystem_changed")
texture=load(img_path)
centered=false
region_enabled=true
region_rect=Rect2(0,0,img_size.x,img_size.y)
print("Merged Images!")
func _init():
self_modulate=Color("#74646464")一旦按下generate_img，它就会创建如下所示的图像：
我添加self_modulate=Color("#74646464")的原因是为了在合并的图像和子精灵(像幽灵图像)之间没有混淆。
虽然我仍然觉得有一个更好的解决方案，如果是这样，请张贴一个。
编辑：
用于中心偏移
func _draw():
var origin_x=0
var origin_y=0
if(centered):
origin_x=-img_size.x/2
origin_y=-img_size.y/2
print("Redrawing")
draw_rect(Rect2(origin_x,origin_y,img_size.x,img_size.y), Color(0,200,0), false, 1.0)
func set_generate_img(new_val=true):
if(not new_val):
return
var screenshot_viewport=Viewport.new()
screenshot_viewport.size=img_size
screenshot_viewport.hdr=false
screenshot_viewport.transparent_bg=true
screenshot_viewport.render_target_v_flip=true
if(centered):
screenshot_viewport.global_canvas_transform.origin=Vector2(img_size.x/2,img_size.y/2)
for child in get_children():
remove_child(child)
screenshot_viewport.add_child(child)
add_child(screenshot_viewport)
screenshot_viewport.set_update_mode(Viewport.UPDATE_ONCE)
yield(VisualServer,"frame_post_draw")
var mergeImg=screenshot_viewport.get_texture().get_data()
mergeImg.save_png(img_path)
for child in screenshot_viewport.get_children():
screenshot_viewport.remove_child(child)
add_child(child)
child.set_owner(get_tree().get_edited_scene_root())
screenshot_viewport.queue_free()
ep_filesystem.scan()
yield(ep_filesystem,"filesystem_changed")
texture=load(img_path)
region_enabled=true
region_rect=Rect2(0,0,img_size.x,img_size.y)编辑2:
修复更暗的透明图像，感谢Theraot's answer (请投它！)
