I've watched every available popular Godot tutorial that others have made and I have to say I'm really appreciating the small stuff you go into. For example, explaining that scripts have different functionality depending on whether they're extending 'node' or 'node2d'. Other people would have assumed the person watching already knew that, but even three weeks into learning Godot I haven't seen this explained anywhere else. Knowing that this functionality is part of Godot gives me the ability to troubleshoot much better, as I can infer that other areas of GDScript work like this too. Absolutely stellar content, you're able to work quickly but nothing feels left out.

Thx Esago! It is difficult at times to assume what a viewer knows and doesn't know. Trying my best to keep the tutorials friendly for anyway without making them to lengthy for others. Glad the work is appreciated!

@@GameDevelopmentCenter You really have an awesome way of explaining how it works without making it too confusing. Most tutorials I watch I don't think id be able to re create what i just watched without going back over the video. After watching yours though, I feel like I know what I'm doing.

i dont get the inheritance used as in the video, what is the point if u still have to copy and paste the path to each scene, how is that diferent from copy-paste the code? Shouldnt the scenes in "Turrets" (Lets say, if i create a new scene in the "Turrets" node) automatically inherit from any script in "Turrets"? Great tutorials anyways thanks.

Fumbling away at Godot with no idea how to use it is incredibly frustrating, Superabundant options and settings and capabilities and I can't make any of them do anything. Following along with a tutorial from someone who really knows what they're doing in Godot is a real eye opener, though. It's shocking what can come together with a bit of clicking and a couple lines of code.

@randomdood5095 3 жыл бұрын

When I scripted it, the right side of the turret is turning to look at the cursor, not the front of the turret, may you help me fix that?

@GameDevelopmentCenter 3 жыл бұрын

We haven't coded turret movement in yet apart from looking at the cursor for demonstration purposes. The tutorial for enemies is just out, over the next couple of episodes we will make the turret turn to the enemy. And look in a single direction when building :)

Почему ты не используешь class_name? Так проще указывать, от какого класса наследован класс. / Why aren't you using class_name? This makes it easier to indicate which class the class inherits from.

@SpyrosSolda 3 жыл бұрын

Yes , having class_name = Turret and then using extends Turret seems more logical. Also I think it's better to use onready var turret := $Turret instead of get_node()

I came across one issue that may just be my own fault, but the barrel of the tank is not following my cursor exactly as intended with get_global_mouse_position(). It is offset like 90 degrees. I read a bunch of forums and cannot seem to understand why. im thinking it could possibly be the way i imported the sprites. I was wondering if anyone else came across this issue? please let me know thank you! p.s. Love this series!

@GameDevelopmentCenter 3 жыл бұрын

The barrel of your tank, or the barrel of your tower? We rotated the sprites before import. If you didn't a 90 degree offset is expected to occur

@TheSuikoEnjoyer 3 жыл бұрын

I was wondering if it was possible to create custom nodes, or node templates to be exact and then inherit from those? As in 'parentTurret' which would have 2 sprites, a muzzle etc and then just use it as a template for other nodes?

@GameDevelopmentCenter 3 жыл бұрын

It is possible to have a default turret scene and load the sprites and set the muzzles through code. You would store a dictionary with all that information and reference it when the tower has to come into the game. So yes, absolutely possible, but it has no place in a beginner tutorial :)

@johnnyxp64 2 жыл бұрын

hi, at 20:50 while you create a new "script" you could use the "Inherit" property and click the folder icon and point the Turrets script so that it makes the new one and puts the inherit code on top by it self. Isnt this the exact same result?

Probably is, never used it though

I *think* maybe you have some explorer extension that lets you rotate right from the context menu because I totally do not have that. I do have "convert image" which allows you to do a lot of things including that rotation though so it was simple enough to use that. But I have never seen that "rotate right" option in any install of windows 10 that I've been on (and I manage hundreds of PCs across multiple companies). Perhaps it's something you have to enable somewhere?

I don't know. I googled it before using this option in the tutorial, and Google said it is totally standard from Windows 10

Would it be possible to attach the same script to both the turrets, as an alternative to extending the script?

@GameDevelopmentCenter 3 жыл бұрын

Not impossible I believe although that isn't going to give us the flexability we need in future tuturials.

@speed2cz 3 жыл бұрын

Is extending the script better than setting the Turrets as a class, and inheriting the new custom class?

@GameDevelopmentCenter 3 жыл бұрын

I don't think there is much difference. For something that has pretty much one use, like in this case, I usually extend the script. If it works more like a tool, that I may export to other projects, I make it a class. Do what has your preference :)

Would it be a good idea to set the physics fps higher to accommodate monitors with higher refresh rates: 144+ ? Thanks for the great tutorial.

@liam99c 3 жыл бұрын

No, if you want smooth movements then you should use func _process(), which calls the function every frame. Using a higher physics fps will make smoother movements but will slow down the game if any more computationally difficult things, like physics, are called on func _physics_process().

@@liam99c yes but in Godot we use the physicsbody2D nodes which are supposed to run in physics_process(). If you wanted to make smooth movement using kinematicbody2D how would you accommodate higher refresh rates?
