INTEGRATION PLANS

Entry CriteriaA level! The Player, Enemies, AnimationsContentCollisionsEvent Triggers

INTEGRATION PLANS Entry Criteria for Lauren’s Work:

AnimationsPlayer (idle, walking, etc…)Enemy (attacking, moving, etc…)

Content ModelsLevel objects (levers, buttons, etc…)Static scene objects (statues, torches, etc…)

INTEGRATION PLANS

Entry Criteria for Nick’s Work: Extending the model pipeline

Introduction of collision volumes

Extend the engine classes Create game classes: Player, camera, etc…

INTEGRATION PLANS

Entry Criteria for Dan’s Work:A.I. Algorithms

Object resolutionDecision making styles

SoundAudio ManagerEffects & Music are fully mixed

INTEGRATION SEQUENCE1. Create a level!

2. Extend the engine classes

3. Extend the game classes (cam, input, etc)

4. Add player, enemies, and objects

5. Collision detection algorithm

6. Add events (objects collide, enemy sees player, player picks up item, etc…)

7. Event handling (play sound, move player/enemy, add item to inventory, etc…)

INTEGRATION PLANS (1. CREATE A LEVEL)

INTEGRATION PLANS (2. EXTEND ENGINE CLASSES)

Ability to interact with game classesManage classes & update scene

INTEGRATION PLANS (3. EXTEND GAME CLASSES)

Add game classes:PlayerInputCameraEnemiesObjectsTriggers

INTEGRATION PLANS (4. ADD PLAYER, ENEMIES, OBJECTS) Import modelsAdd objects

INTEGRATION PLANS (5. COLLISION DETECTION)

Collision Detection HierarchyBounding boxCollision VolumesTriangle Intersection

INTEGRATION PLANS (6. EVENTS)

Player interactions Walk / Run / Climb / CrawlPick up / use itemAttack

EnvironmentMove objectLight torchLevers, buttons, pulleys

Enemy interactionsSee playerMoveAttack

INTEGRATION PLANS (7. EVENT HANDLING)

Player interactionsSound effects (footsteps, exertion, clothes, attacking, etc…)Item Management (update inventory, controls, etc…)Attack (weapons do damage, take damage/wear, etc….)

EnvironmentSound effects (objects dragging, flying, burning, exploding, etc…)Particle effects (torch’s fire, dust from wind, mist from splash, etc…)

Enemy interactionsDecide how to get to player in the quickest mannerAttack when in rangePlay sound effects for certain attacks (arrow shot, sword clangs, etc…)

SO THAT'S A GAME, RIGHT?

There’s still a lot to do!Great framework set up
