Crayta lets you assign a ‘grip’ to a player. A grip defines the set of movement animations that this player will start using. For example, setting a player’s grip to Shotgun will see the player run, jump, crouch, etc, as if they were holding a shotgun with both hands. Switching this to Melee will switch these animation to a one-handed hold of a sword-like weapon. It is up to your game to attach shotguns/swords/whatever to your player’s hands in conjunction with setting the grip type.

Depending on the grip that has been assigned various actions can be played. For example, if the player is using the Shotgun grip, they can do a Fire or Reload action. However, when using the Melee grip, there is no such thing as a reload (you can’t reload a sword!), so that doesn’t have a Reload action.

To trigger an action, for example a reload, just call self:GetEntity():PlayAction(“Reload”). PlayAction takes an optional second parameter, which is a table of optional parameters for this animation.

Name	Type	Description
`playbackSpeed`	number	Sets the speed to play this animation at. 2 = double speed, 0.5 = half speed. Note: If `playbackTime` is also set, you’ll get a warning, and `playbackTime` will be preferred)
`playbackTime`	number	Sets the time that this animation should take. 1 = 1 second, 10 = 10 seconds. Note: If `playbackSpeed` is also set, you’ll get a warning, and `playbackTime` will be preferred)
`events`	Table of lua functions	Some actions trigger events – these are functions that will be triggered in your Lua code once the animation for an action reaches a certain point. An event can be either a standard event, or a branching event. A standard event expects your lua function to return nothing. A branching event expects your lua function to return a bool. Events can be omitted from this table, if a branching event is omitted, the default return value for this branching event will be used. See examples of events below.

Example

Here’s an example of a reload action for a shotgun grip being performed at double speed, with the IsReloadComplete and AmmoAdded action events implemented. The reload animation will keep on playing until the number of self.bullets reaches self.properties.maxBullets

local animData = {}
animData.playbackSpeed = 2.0
animData.events =
    {
        IsReloadComplete = function ()
           Print("Checking if full")
           return self.bullets == self.properties.maxBullets
        end,
        AmmoAdded = function ()
            self.bullets = self.bullets + 1
            Print("Added Bullets, current ammo = " .. self.bullets )
        end
    }
    self:GetEntity():PlayAction("Reload", animData)

Global Events

OnCompleted – This applies to all actions and will trigger once the animation for the action is no longer playing
