ResolverObject & | ro |
Surrounding resolver object. |
Interface to query and set values specific to a single VarSpriteGroupScope (action 2 scope).
Multiple of these interfaces are combined into a ResolverObject to allow access to different game entities from a SpriteGroup-chain (action 1-2-3 chain).

Get a few random bits.
Default implementation has no random bits.

Get a variable value.
Default implementation has no available variables.
variable | Variable to read | |
parameter | Parameter for 60+x variables | |
[out] | available | Set to false, in case the variable does not exist. |

pos | Position to store into. |
value | Value to store. |
