The ActionQueue is a set of actions and durations within which those +actions may be applied. This will solve the issue of buffering inputs as well as having multiple systems control which +actions an entity might take (for a future AI system, perhaps?). + +Let's introduce the jumping mechanics of this game as an example of the system interaction with entities. + +When the player presses a key mapped to a Jumping action, a Jump action is queued and expires in 80 milliseconds. +The JumpSystem consumes the action if the entity is able to "physically" jump: +- it is in contact with a solid underneath and has zero velocity on the y axis (?) and there is no current Jump component +- or, there is a Jump component but the "availableJump" counter is greater than zero (it is decremented on consumption + of the Jump action), to account for the future of a double jump being possible. + +If the JumpSystem does not consume() the action within the allotted 80 milliseconds, the action expires and is removed +from the queue. + +The queue is an action-singleton queue. Meaning, enqueueing an action has the effect of replacing any action of the same +type whose expiration is earlier than the enqueued action. + |
