Gears are dynamic objects or events in the world that affect the gameplay, including hedgehogs, projectiles, weapons, land objects, active utilities and a few more esoteric things. Visual gears are decorational objects which are usually used for purely decorational graphical effects. They have no effect on gameplay. Visual gears are not the same as gears, but they share some similarities.

The initial velocities are `dx` and `dy`. All arguments are numbers. The function returns the `uid` of the gear created. Gears can have multple states at once: `state` is a bitmask, the flag variables can be found in [States]. `timer` is the initial timer value of the gear. If a particular gear value does not matter, use `0`.

Note: If you want to create a hedgehog (`gtHedgehog`), you must call `AddHog` or `AddMissionHog` instead. If you want to spawn a crate (`gtCase`), you must call one of the several “Spawn*Crate” functions (e.g. `SpawnSupplyCrate`) below instead.

The function returns the `uid` of the visual gear created or `nil` if creation failed.  There is no guarantee that a visual gear will spawn.  *IMPORTANT: Do not rely on visual gears to spawn*. *Always* be prepared for this function to return `nil`.

Set `critical` to `true` if the visual gear is crucial to gameplay and must always be spawned when in-game.  Use `false` if it is just an effect or eye-candy, and its creation can be skipped when in fast-forward mode (such as when joining a room).

*NOTE:* Visual gears *must* only be used for decorational/informational/rendering purposes. *Never* use the visual gear's internal state to manipulate anything gameplay-related. Visual gears are not safe for reliable storage and using them as that would lead to strange bugs.

*NOTE:* Since 0.9.25, visual gears will never spawn when Hedgewars is run in a testing mode (i.e. not as the real game), so don't rely for visual gears to spawn even if they're critical.

`botlevel` ranges from `0` to `5`, where `0` denotes a human player and `1` to `5` denote the skill level of a bot, where `1` is strongest and `5` is the weakest. Note that this is the reverse order of how the bot level is displayed in the game. Note that mixing human-controlled and computer-controlled hedgehogs in the same team is not permitted, but it is permitted to use different computer difficulty levels in the same team.

If `ammoType` is set to `amNothing`, a random weapon (out of the available weapons from the weapon scheme) will be selected. If `x` and `y` are set to 0, the crate will spawn on a random position (but always on land). The `amount` parameter specifies the amount of ammo contained in the crate. If `amount` is `nil` or `0`, the value set by `SetAmmo` is used, or if `SetAmmo` has not been used, it falls back to the weapon scheme's value. If `amount` is equal to or greater than `AMMO_INFINITE`, the amount is infinite.

The `Tag` of a gear is just another arbitrary variable to hold the gear's state. The meaning of a tag depends on the gear type. For example, for `gtBall` gears, it specifies the ball color, for `gtAirAttack` gears (airplane) it specifies the direction of the plane, etc. See [GearTypes] for a full list. The returned value will be an integer.

This is an invisible circle around the center of the gear which is used for the collision checks. For a few gear types, its radius means something different, see [GearTypes] for a full list.

For example: The `FlightTime` of a hedgehog (`gtHedgehog`) is the time since they last have stood on solid ground. For most projectile gear types (i.e. `gtShell`), it stores the time after it has been launched.

Specifically, this increases the health of the hedgehog gear with the given ID `gearUid` by `healthBoost`, displays some healing particles at the hedgehog and shows the health increae as a message. This is similar to the behavour after taking a health crate, or getting a health boost from vampirism.

If `showMessage` is false, no message is shown. With `tint` you can set the RGBA color of the particles (default: `0x00FF00FF`).
