PureMVC
●
Organize your code is small units
●
Let those units communication
●
Standardize your code
●
Focus on app instead of
architecture
●
Ported to many languages
●
Slightly hurts performance
●
Built on static classes
●
Lot of boilerplate code
Can't it be done simpler?
The good The bad
The good The bad
robotlegs
●
All PureMVC goodness.
●
Removed most boilerplate
code
●
Introduces dependency
injection
●
Hurts performance a lot!
Can't it be done simpler...
and run fast?
The good The bad
robotlegs 2 (beta)
●
Highly configurable
●
Modular
●
Guards ,hooks, rules.
●
Adds some boilerplate code
●
Code less standardized
●
Hurts performance a lot
(and more)
I meant faster! Not slower...
The good The bad
mvcExpress
●
All PureMVC and robotlegs
goodness.
●
Focus on modular
development
●
Simplifies code even more
●
Hurts performance the least
●
Young framework
Simplest and fastest MVC framework!

Modular programming
pitfalls
●
Planning is needed
●
Good module should be able to stand
as application on its own
– Chat window
– Stand alone tutorial
●
Worst case scenario: extracting
module/reintegrating module refactoring.
MvcExpress live
mvcExpress live
●
mvcExpress live = mvcExpress + game engine
– Continuous logic execution
– Dynamic animations
– Breaking execution in parts. (batching)
●
Compatible with mvcExpress

Process examplepackage com.mindscriptact.testProject.engine {
public class GameEngineProcess extends Process {
override protected function onRegister():void {
addTask(MoveHeroTask);
addTask(MoveEnemiesTask);
addTask(HeroCollideEnemiesTask);
addTask(EnemySpawnTask);
addTask(ShowHeroTask);
addTask(ShowEnemiesTask);
addHandler(Message.PAUSE_GAME, handleGamePause);
}
private function handleGamePause(isPaused:Boolean):void {
if (isPaused) {
disableTask(MoveHeroTask);
disableTask(MoveEnemiesTask);
} else {
enableTask(MoveHeroTask);
enableTask(MoveEnemiesTask);
}
}
}}
Task example
package com.mindscriptact.testProject.engine.tasks {
public class ShowEnemiesTask extends Task {
[Inject(constName="com.mindscriptact.testProject.constants.ProvideIds.ENEMY_DATAS")]
public var enemyDatas:Vector.<EnemyVO>;
[Inject(constName="com.mindscriptact.testProject.constants.ProvideIds.ENEMY_VIEWS")]
public var enemyImages:Vector.<EnemySprite>;
override public function run():void {
for (var i:int = 0; i < enemyDatas.length; i++) {
enemyImages[i].x = enemyDatas[i].x;
enemyImages[i].y = enemyDatas[i].y;
enemyImages[i].rotation = enemyDatas[i].rotations;
}
}
}}
mvcExpress live testing
package com.mindscriptact.testProject.engine.tasks {
public class ShowEnemiesTask extends Task {
[Inject(constName="com.mindscriptact.testProject.constants.ProvideIds.ENEMY_DATAS")]
public var enemyDatas:Vector.<EnemyVO>;
[Inject(constName="com.mindscriptact.testProject.constants.ProvideIds.ENEMY_VIEWS")]
public var enemyImages:Vector.<EnemySprite>;
override public function run():void {
for (var i:int = 0; i < enemyDatas.length; i++) {
enemyImages[i].x = enemyDatas[i].x;
enemyImages[i].y = enemyDatas[i].y;
enemyImages[i].rotation = enemyDatas[i].rotations;
}
}
}}
[Test]
public function showEnemiesTask_enemyViewAndDataCount_isEqual():void {
assert.equals(enemyDatas.length, enemyImages.length, "Enemies data and view count must be the same!");
}
[Test(delay="500")]
public function showEnemiesTask_enemyViewAndDataPosition_isEqual():void {
for (var i:int = 0; i < enemyDatas.length; i++) {
assert.equals(enemyImages[i].x, enemyDatas[i].x, "Enemy x is damaged. enemyId:" + enemyDatas[i].id);
assert.equals(enemyImages[i].y, enemyDatas[i].y, "Enemy y is damaged. enemyId:" + enemyDatas[i].id);
}
}
Process run speed
●
Best case:
– Runs 1000000 empty Task's in 17 ms
– 58823 empty tasks in 1 ms
●
Worst case:
– 13300 empty tasks in 1 ms
MvcExpress live overview
●
Designed with games in mind but can be used in any
application than has repeating logic to run.
●
Processes and Task's are decoupled
●
Convenient communication with MVC
●
It is possible to break Model and View decoupling
rules, but gives tools to detect it.
●
It is fast!
●
It just works!

  • 56. MvcExpress live overview ● Designed with games in mind but can be used in any application than has repeating logic to run. ● Processes and Task's are decoupled ● Convenient communication with MVC ● It is possible to break Model and View decoupling rules, but gives tools to detect it. ● It is fast! ● It just works!
