Playing animations

Basic

• gkActionManager (singleton) contains all actions of all objects.
• gkGameObject contain a ActionBlender that can prioritize animations and blend after a transition.
• you must first call gkGameObject::addAction("action_name");
• then gkGameObject::playAction("action_name", blend, mode, priority);

Advanced =

• you can get the action player corresponding to a specific action with gkGameObject::getActionPlayer("action_name");
• and jumping across the action with gkActionPlayer::setTimePosition(time);
• you can can also check if an gkActionPlayer isDone() or change its mode (loop,reverse).

Creating animations

• To create an animation (not linked to any object), call gkActionManager::getSingleton().createKeyedAction("action_name"); or gkActionManager::getSingleton().creatActionSequence("action_name");

keyedAction

• Contains a bunch of channels each containing a bunch of keyframed curves.

ActionSequence

• Contains a bunch of ActionStrip with custom end start time for non linear action.
• Action Strip can correspond to any type of action (keyframed or other sequences)

// COMBO: Kick + Run + Whip
m_comboAttack = gkActionManager::getSingleton().createActionSequence("Momo_ComboAttack");
m_comboAttack->addItem("Momo_Kick",      gkVector2(0.f,  17.f), gkVector2(0.f,  3.f));
m_comboAttack->addItem("Momo_Run",       gkVector2(15.f, 32.f), gkVector2(2.f,  4.f));
m_comboAttack->addItem("Momo_TailWhip",      gkVector2(25.f, 45.f), gkVector2(7.f,  0.f));
m_animations[= m_skeleton->addAction(m_comboAttack);
m_animations[GK_ANIM_COMBO_ATTACK](GK_ANIM_COMBO_ATTACK])->setMode(GK_ACT_END); //not LOOP

Notes

• NLA action are not converted to gkActionSequence yet.
• Only Bone and Object (loc/rot/scale) for now.
