Any sport on the market wants belongings like textures, sounds, and music to supply a enjoyable expertise to its gamers. Godot treats these recordsdata as sources you should utilize all through your challenge.
In addition to Godot’s built-in sources, you can even create your individual to construct highly effective, modular methods. Customized sources make it simpler to handle your challenge. You possibly can even use sources to maintain observe of the sport’s progress and retailer the data on disk.
On this tutorial, you’ll create a store the place gadgets can be found on the market. There’s a twist although: the store sells monsters! Whereas engaged on the challenge, you’ll be taught:
- What sources are and find out how to use them
- How Godot handles the loading of sources
- Methods to create your individual sources
- Tips on how to save and cargo the state of sources
Getting Began
To begin off, obtain the supplies for this challenge by clicking the Obtain supplies hyperlink on the high or backside of this web page. Unzip the recordsdata and open the MonsterShop challenge you’ll discover within the starter folder in Godot.
As soon as the challenge has loaded, check out the FileSystem tab to see the included recordsdata.
Most of those are textures and sound recordsdata to make the challenge really feel extra alive. The scenes folder is very essential, it has three scenes in it you’ll be constructing upon. Open these scenes within the editor to familiarize your self with them.
Store
The store scene is the principle scene of the sport. That is the place you’ll be spending most of your time because it’s the one display the participant will see. It comprises a shifting background, some background music by way of an AudioStreamPlayer node, and a CanvasLayer that maintain the UI components.
Press F5 to run the challenge and see the store scene operating.
Be aware: Should you desire no music whereas operating the sport, you possibly can change disable Autoplay within the BGM node.
Participant Merchandise Show
Subsequent, open the player_item_display scene.
This can be a easy coloured sq. which can present a single merchandise within the participant’s stock. Extra on that afterward!
Store Merchandise Show
Lastly, open the shop_item_display scene.
This can be a card-like show that can present a single merchandise within the store, together with a purchase button.
Now that you’ve an thought of how the store works, it’s time to take a more in-depth take a look at sources.
What are Sources?
Sources are information containers that nodes in your challenge can use. They will maintain many properties, reference different sources and might comprise capabilities to govern the info.
Any file which you could load from and save to disk turns into a useful resource after importing. This consists of scenes, textures, sounds, scripts, meshes and fonts.
Godot comes with an enormous library of supported sources, and you can even create your individual customized useful resource tailor-made to your wants.
Importing and Utilizing Sources
The starter folder comprises a folder referred to as monsters with some sprites in them you’ll want for the store.
To import sources, you’ve gotten two choices:
- Copy the recordsdata into the challenge folder
- Drag-and-drop the recordsdata into the FileSystem dock
Most builders go along with the second possibility, so choose the sprites folder within the FileSystem dock and drag the monsters folder out of your file supervisor into the FileSystem dock.
That’s it, the sprites are actually imported into the challenge as sources. Yow will discover them within the monsters folder within the FileSystem dock.
Making use of a Sprite Texture
To check if Godot imported the sprites accurately, you possibly can apply considered one of them as a texture to a node. To take action, open the shop_item_display scene and choose the SpriteTexture node. Now check out the Inspector and drag one of many imported sprites onto the Texture property.
You need to now see the sprite seem within the circle on the high of the merchandise show.
Subsequent, take a more in-depth take a look at the Texture property and its Load Path. You’ll discover that the trail isn’t set to the png file within the monsters folder, however relatively to a ctex file in a .godot/imported folder. What provides?
Each time Godot imports a texture, it creates a ctex file within the .godot/imported folder. A ctex file is a compressed texture file that Godot makes use of to retailer textures effectively. You possibly can change the best way Godot compresses textures by way of the import parameters.
Import Parameters
Check out the import parameters by choosing one the monster sprites within the FileSystem dock and opening the Import tab within the Scene dock.
Each exterior useful resource sort has its personal set of import parameters so that you can change. For picture recordsdata, you possibly can change how Godot makes use of the feel. For instance, you could possibly use the picture as a cubemap or as font as an alternative of a Texture2D.
You possibly can change the compression mode with the Mode property beneath the Compress class.
By default, Godot shops photographs as lossless textures on the GPU. This implies they’re uncompressed, and there gained’t be any lack of high quality when in comparison with the unique picture. If you need the feel to have a smaller reminiscence footprint and cargo sooner, you possibly can change the compression mode to VRAM Compressed. Doing so will compress the feel on the GPU. The draw back is that this may introduce seen artifacts within the texture. As a rule of thumb, hold textures meant for 2D lossless, and use VRAM compressed textures for large 3D textures.
Exterior vs Constructed-in Sources
Now focus your consideration on the Texture property of the SpriteTexture node once more. There’s a Useful resource property there, click on on it to broaden its values.
The Useful resource property has three values:
- Native to Scene: By default, Godot shares sources between scenes. Because of this any modifications you make in a single scene might be mirrored in all different scenes. By enabling native to scene, the useful resource will solely be shared in a single scene.
- Path: For this sprite, this factors to the trail to the useful resource file contained in the FileSystem dock.
- Identify: An non-obligatory identify for the useful resource.
You possibly can’t edit these values because the sprite is an exterior useful resource. This implies the useful resource is saved on the disk as a file. In consequence, it would at all times be shared throughout scenes and each its path and identify are pre-defined.
Godot additionally lets you use built-in sources which might be saved with the scene file. Within the case of textures, these are sometimes gradients and noise textures which you could generate inside Godot itself. For instance, right-click the Texture property of the SpriteTexture node and choose New NoiseTexture2D within the checklist.
It will create a brand new NoiseTexture2D useful resource. To generate some noise, click on the Noise property and choose New FastNoiseLite.
You’ll now see the noise texture seem within the scene view.
Each the NoiseTexture2D and the FastNoiseLite sources are saved within the scene itself. Because of this they’re referred to as built-in sources. It can save you these sources to disk by right-clicking any of them and choosing Save. For the needs of this text, you gained’t want them, nevertheless it’s good to remember to your personal initiatives.
Constructed-in sources which might be saved to disk might be reused in different scenes as exterior sources. That is helpful if you need to generate a selected useful resource solely as soon as and reuse it in a number of scenes.
Subsequent, level the Texture again to a monster sprite by dragging one of many sprites from the FileSystem dock to the Texture property of the SpriteTexture node such as you did earlier than.
Now that you recognize the ins and outs of sources, it’s time to check out find out how to create your individual.
