之前用的版本是2.0.1的版本，后来又用2.1.1重新写了一部分，现在全新开始，就用最新的版本，cocos2d-x-3.0beta，这个版本和之前的相比变化挺大的。
首先，肯定就是加载地图了，这里我用的是地图编辑器tIDE Tile Map Editor，具体用法请点击下面的链接
http://blog.csdn.net/nat_myron/article/details/8763570
这是用的背景的素材
程序实现方法：
//===========加载背景地图=============
auto bg = TMXTiledMap::create("bg.tmx");
bg->setPosition(Point(0,0));
this->addChild(bg,0);
这样就可以把我们编辑好的地图加载到场景中了，再修改一下bg.tmx文件，记录一下我们的路线。
<objectgroup name="path" width="60"height="60"> <objectx="0" y="5"/> <objectx="2" y="5"/> <objectx="2" y="2"/> <objectx="4" y="2"/> <objectx="4" y="4"/> <objectx="7" y="4"/> <objectx="7" y="6"/> <objectx="11" y="6"/> <objectx="11" y="0"/> </objectgroup>
程序中初始化路线的方法：
auto map = TMXTiledMap::create("bg.tmx");
auto group = map->getObjectGroup("path");
auto& objects = group->getObjects();
for (auto& obj : objects)
{
ValueMap& dict = obj.asValueMap();
int x = dict["x"].asInt();
int y = 480 - dict["y"].asInt();
wayPoint.push_back(Point(x,y));
wayCount++;
}
容器wayPoint记录tmx文件中的点。
好了，现在背景有了，路线也有了，接下来就是怪物了。
怪物的素材图
读取方法：
void Enemy::uploadEnemy()
{
//RightMove()
Vector<SpriteFrame*>tempRightMove;
for (int i = 8; i < 12; i++)
{
tempRightMove.pushBack(Myframes[i]);
}
Animation* aniRightMove = Animation::createWithSpriteFrames(tempRightMove,0.2f);
actionRightMove = Animate::create(aniRightMove);
actionRightMove->retain();
//LeftMove()
Vector<SpriteFrame*>tempLeftMove;
for (int i = 4; i < 8; i++)
{
tempLeftMove.pushBack(Myframes[i]);
}
Animation* aniLeftMove = Animation::createWithSpriteFrames(tempLeftMove,0.2f);
actionLeftMove = Animate::create(aniLeftMove);
actionLeftMove->retain();
//UpMove()
Vector<SpriteFrame*>tempUpMove;
for (int i = 12; i < 16; i++)
{
tempUpMove.pushBack(Myframes[i]);
}
Animation* aniUpMove = Animation::createWithSpriteFrames(tempUpMove,0.2f);
actionUpMove = Animate::create(aniUpMove);
actionUpMove->retain();
//DownMove()
Vector<SpriteFrame*>tempDownMove;
for (int i = 0; i < 4; i++)
{
tempDownMove.pushBack(Myframes[i]);
}
Animation* aniDownMove = Animation::createWithSpriteFrames(tempDownMove,0.2f);
actionDownMove = Animate::create(aniDownMove);
actionDownMove->retain();
}
创建怪物：
void GameScene::addEnemy()
{
//============增加一个怪物==============
auto enemy = Enemy::create();
enemy->setPosition(Tools::ConvertViewPoint(DataManage::getInstance()->wayPoint[0]));
this->addChild(enemy,1);
DataManage::getInstance()->v_enemy.push_back(enemy);
}
怪物的移动：
void Enemy::run()
{
if (this->iTurn< RoadCount - 1 && this->hp > 0)
{
Point point1 = DataManage::getInstance()->wayPoint[iTurn];
Point point2 = DataManage::getInstance()->wayPoint[iTurn+1];
Point p0 = Tools::ConvertViewPoint(point2);
Point p = this->getPosition();
//帧动画
if(point2.x - point1.x == 0)//垂直
{
if(point2.y - point1.y >= 0 )
{
if (iChangeDire!=1)
{
this->stopAllActions();
this->runAction(RepeatForever::create(actionDownMove));//1
iChangeDire = 1;
}
p.y -= this->speed*1;
if (p.y-p0.y<=0)
{
iTurn++;
p = p0;
}
}
else if(point2.y - point1.y < 0 )
{
if (iChangeDire!=2)
{
this->stopAllActions();
this->runAction(RepeatForever::create(actionUpMove));//2
iChangeDire = 2;
}
p.y += this->speed*1;
if (p.y-p0.y>=0)
{
iTurn++;
p = p0;
}
}
}
else if(point2.y - point1.y == 0)//水平
{
if(point2.x - point1.x > 0 )
{
if (iChangeDire!=3)
{
this->stopAllActions();
this->runAction(RepeatForever::create(actionRightMove));//3
iChangeDire = 3;
}
p.x += this->speed*1;
if (p.x-p0.x>=0)
{
iTurn++;
p = p0;
}
}
else if(point2.x - point1.x <= 0 )
{
if (iChangeDire!=4)
{
this->stopAllActions();
this->runAction(RepeatForever::create(actionLeftMove));//4
iChangeDire = 4;
}
p.x -= this->speed*1;
if (p.x-p0.x<=0)
{
iTurn++;
p = p0;
}
}
}
this->setPosition(p);
}
//else if(this->iTurn >= RoadCount-1)
//{
// this->removeFromParentAndCleanup(true);
// DataManage::getInstance()->v_enemy.erase(pos);
//}
}
怪物出现的时间写在一个plist里
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

读取方法：
__Dictionary* plistDic = __Dictionary::createWithContentsOfFile("level1.plist");
__Dictionary* levelDic = dynamic_cast<__Dictionary*>(plistDic->objectForKey("level1"));
char str[10];
for (int i=1;i<=levelDic->count();i++)
{
sprintf_s(str,"%d",i);
__Dictionary* farScene = dynamic_cast<__Dictionary*>(levelDic->objectForKey(str));
__String* spriteName = dynamic_cast<__String*>(farScene->objectForKey("time"));
float time = spriteName->floatValue();
v_time.push_back(time);
}
主场景开启一个定时器，遍历所有的怪物，让怪物出现并跑起来
void GameScene::update( float dt )
{
//==========enemy run================
vector<Enemy*>::iterator it=DataManage::getInstance()->v_enemy.begin();
while(it!=DataManage::getInstance()->v_enemy.end())
{
if((*it)->iTurn >= (*it)->RoadCount-1)
{
(*it)->removeFromParentAndCleanup(true);
it = DataManage::getInstance()->v_enemy.erase(it);
}else
{
(*it)->run();
it++;
}
}
//========enemy show time===================
vector<float>::iterator it_time=DataManage::getInstance()->v_time.begin();
while(it_time!=DataManage::getInstance()->v_time.end())
{
float tmp = fabs(time-*it_time);
if(( tmp>-0.0001) && (tmp < 0.0001))
{
addEnemy();
it_time = DataManage::getInstance()->v_time.erase(it_time);
}else
{
it_time++;
}
}
time += 1.0/60;
}坐标转换函数
Point Tools::ConvertViewPoint( Point p )
{
return Director::getInstance()->convertToGL(CCPoint(p.x * 60 + 30, p.y * 60));
}
看一下运行图
这一篇就到此为止了。
