All about bullets. When I write “bullet” or “standard bullet”, that’s what I’m talking about. Different from a BulletNode.
They’re not nodes. For optimisation reasons. This might make the whole thing a bit obscure. Basically, I directly call the Physic2DServer to create collision shapes. Each bullet is a collision shape linked to an Area2D : the Shared Area
For the visuals, I call draw() with the bullet’s texture. If the bullet is animated, the draw calls change to reflect that.
Bullets are stored in Spawning in a Dictionnary called poolbullets where the key is the collision’s RID and the value is the bullet data, represented by a Dictionnary.
<aside> 💡 A RID in Godot stands for Resource ID, it’s a unique identifier for every resource, such as collision shapes. Low level calls to Godot’s functions often use them.

The bullet data holds its position and other data that are specific to each bullet. There’s also a reference to itsBullet Props. Since the props are a resource, they are the same for all bullets using them. That’s why the data specific to each bullet is in the bullet data dictionnary.
Bullets are data structures represented as Dictionaries. They have the following entries :
General properties shared by all bullets and BulletNodes.
speed : bullet’s speed.position : bullet’s positionvel : bullet’s velocity.shape_disabled: if the bullet’s collision is disabled.shared_area: The Shared Area the bullet belongs to.props: a link to the Bullet Props, converted into a Dictionary by [☄️Sanitize_bulletprops(props:PackedDataContainer, id:String, source:Node): removes unnecessary bloat from bulletprops and returns a clean dictionary. If you create a Bullet Props yourself by code, you need to call this before using your props or else it won’t be formatted correctly. A source node is necessary for get_node() calls (for targeting a node). Generally, calling with self (aka, the script calling the function) is ok. In versions V4.3 and below, this function isn’t part of the API and is only available in the BulletPattern node.](https://dark-peace.notion.site/Sanitize_bulletprops-props-PackedDataContainer-id-String-source-Node-removes-unnecessary-bloat-f-765755c7ceda4144a2f76bbd69e766ff).source_node: The link to the spawner, whether it’s a node or a Dictionary.state: One of the following : enum BState{Unactive, Spawning, Spawned, Shooting, Moving, QueuedFree} . I think it speaks for itself.spawn_pos : global position at which the bullet will spawnrotation : global rotation of the bulletRID: RID of the shape or reference to the node, depending of the prop type.Properties for standard bullets only.
