Problem with setPosition

[flamendless]

i need help with this:

--init
local active_camera = Gamera.new(0, 0, 1024, 512)

--in draw
local screen_x, screen_y, screen_w, screen_h = active_camera:getWindow()
local world_x, world_y, world_w, world_h = active_camera:getWorld()
local dx = Imgui.SliderInt("x", screen_x, 0, world_w)
local dy = Imgui.SliderInt("y", screen_y, 0, world_h)
print(dx, dy) --works
active_camera:setPosition(dx, dy)
print(active_camera:getWindow()) --should be updated, but prints 0, 0, 1024, 512 still

the position value of the window should change, but it returns to 0 :/

setPosition changes the x and y position of the Window (subset of World), but it resets to 0

ive tried

active_camera.x = dx
active_camera.y = dy

but instead of resetting to 0, it resets to 512 (half of 1024), because internally gamera computes position and width since (0,0) in camera coordinates is center

I think you misunderstood what position is and what window is in gamera.

Imagine a news reporter moving around on his car, shooting footage with their camera. And then imagine a person sitting on their living room, watching the news on their TV.

• The coordinates the news camera is looking at is position.
• The coordinates of the person watching the news on their living room is the window.

They are related, in a way, but not in the way you are thinking. If the position changes, the content showed on the window will change, but the window will not move.
