In this particular video we'll give our camera the ability to pan and zoom.

-----
In this series I'll show you how to make your own remix of Rimworld, or any similar top-down colony management/strategy game.
Puzzling out how to make a game you know is a great way to learn, we're obviously not going to make an exact copy, but we'll develop a lot of the features that make the game, and maybe even spin it off into something unique.
You can find the finished camera script here.

next video ideas: -Grid based object placement| -Terrain layers that dictate impassable movement (touched already in video 2) -Object generation within terrain generation for resources -UI -Animations for the world/objects/pawns Love these videos man, keep it going!!

SO many yasss for the grid object placement tutorial, especially for isometric ones.

[@mrussogamedev]

YES for the edge detection for camera/mouse please! Really curious to see it handling a procedural generated like this one.

[@signet2712]

Great tutorial series and explanations! Please keep it going!

[@SoggyNoodle9]

As some one involved with rimworld for a long time it's really fun to see a tutorial based on it, I'm glad you're taking the time to make the functions act the way you want them too and you explain it great while at it as well!

[@sphynxcolt4030]

Very nice tutotial! Camera movement & zoom is so important. Super cool that you did not just call it a day with the snappy zoom and panning, as maybe most would have, but even added camera smoothing. Really looking forward to what comes next :D

Been looking for a series like this for godot for quite some time, thanks for doing this, much appreciated

[@FatMiddleAgedMan]

You have an excellent way of explaining things and fantastic pacing! Loving this series so far - keep up the amazing work! :D

[@CoFloCipher]

Happy to see another video. I’m loving this series so far! One small suggestion - try zooming in the view when writing code and when showing small ui elements. This can be done in post if you don’t remember to while filming. Again, awesome job so far and I can’t wait to see more!

[@real_robots]

Thanks, I had the same comment on a previous video and then I completely forgot to do anything about it with this one. Next video is going to have big chunky text, I promise!

[@omeed9015]

Thanks so much for taking the time to post these!

[@DJRTMC]

damn thats good material stuff

[@brunch1572]

Great video. I love the series. I made a couple modifications that I thought I'd share with anyone interested. The first is setting limits to zooming in and out. The second is making it so that in order to drag the camera, you must hold the drag toggle (space bar in my case) and then left click and drag. This functions like the Godot 2D editor and also like Aseprite. Zoom limits: 2 new variables and modified zoom_camera function var zoom_min: Vector2 = Vector2(0.1, 0.1) var zoom_max: Vector2 = Vector2(5.0, 5.0) func zoom_camera(delta): if Input.is_action_just_pressed("camera_zoom_in"): zoom_target *= 1.1 elif Input.is_action_just_pressed("camera_zoom_out"): zoom_target *= 0.9 zoom_target = clamp(zoom_target, zoom_min, zoom_max) #

[@real_robots]

Zoom limits are a great idea, I can't believe I forgot to add those in

[@DejaimeNeto]

yes

[@JFLEEC]

nice !

[@katherine2721]

Sorry but is there a reason to put this in the process function instead of _input(event) function?

[@real_robots]

Nope, not any good one. Only that I tend to prefer understanding my code a tick at a time and find events strange and confusing :-)

[@katherine2721]

@@real_robots That makes sense. I get a bit paranoid about multiple checks every tick (even though I doubt it's a real problem unless it's hundreds or thousands of nodes) so I try to put fewer things in process. But great series, keep going! Especially since I'm replaying Rimworld because of the anomaly update!

[@jakes-dev1337]

The terrain generates multiple times on click, so thats perfectly reasonable​@@katherine2721
