The idle action
The blackboard can also be used for temporary data, such as the idle action's
idleEndTime
data. Once the idle action terminates, we merely set the blackboard attrib-
ute to
nil
in order to remove it from the blackboard:
SoldierActions.lua
:
function SoldierActions_IdleInitialize(userData)
userData.controller:QueueCommand(
userData.agent,
SoldierController.Commands.IDLE);
local sandboxTimeInMillis =
Sandbox.GetTimeInMillis(userData.agent:GetSandbox());
userData.blackboard:Set(
"idleEndTime",
sandboxTimeInMillis + 2000);
end
function SoldierActions_IdleUpdate(deltaTimeInMillis,
userData)
local sandboxTimeInMillis =
Sandbox.GetTimeInMillis(userData.agent:GetSandbox());
if (sandboxTimeInMillis >=
userData.blackboard:Get("idleEndTime")) then
userData.blackboard:Set("idleEndTime", nil);
return Action.Status.TERMINATED;
end
return Action.Status.RUNNING;
end
