1.放置太陽花和豌豆射手卡片

2.基本思路

• 太陽花卡片的起始X位置 = 根據(jù)狀態(tài)欄的X坐標(biāo) + 1個(gè)圖片寬度
• 豌豆射手卡片的起始X位置 = 根據(jù)狀態(tài)欄的X坐標(biāo) + 2個(gè)圖片寬度

// 狀態(tài)欄位置 + 一張圖片寬度int statusX = (Config.screenWidth - Config.seekBank.getWidth()) / 2;int locationX = statusX + Config.seedFlower.getWidth();SeedFlower seedFlower = new SeedFlower(locationX, 0);gameLayout2.add(seedFlower);// 豌豆射手locationX = locationX + Config.seedPea.getWidth();SeedPea seedPea = new SeedPea(locationX, 0);gameLayout2.add(seedPea);

3.開發(fā)細(xì)節(jié)

3.1 卡片對(duì)象-基類

package com.su.botanywarzombies.model;import android.graphics.Canvas; import android.graphics.Paint;public class BaseModel {// 對(duì)象的起始X坐標(biāo)public int locationX;// 對(duì)象的起始 Y坐標(biāo)public int locationY;// 是否還活著public boolean isLive;// 位置的自我繪制public void drawSelf(Canvas canvas, Paint paint) {} }

3.1 卡片對(duì)象-接口類

package com.su.botanywarzombies.model;public interface TouchAble {void onTouch(); }

3.2 太陽花卡片對(duì)象

繼承基類并實(shí)現(xiàn)接口

package com.su.botanywarzombies.entity;import android.graphics.Canvas; import android.graphics.Paint;import com.su.botanywarzombies.constant.Config; import com.su.botanywarzombies.model.BaseModel; import com.su.botanywarzombies.model.TouchAble;public class SeedFlower extends BaseModel implements TouchAble {public SeedFlower(int locationX, int locationY) {this.locationX = locationX;this.locationY = locationY;this.isLive = true;}@Overridepublic void drawSelf(Canvas canvas, Paint paint) {if (isLive) {canvas.drawBitmap(Config.seedFlower, locationX, locationY, paint);}}@Overridepublic void onTouch() {}}

3.2 豌豆射手卡片對(duì)象

package com.su.botanywarzombies.entity;import android.graphics.Canvas; import android.graphics.Paint;import com.su.botanywarzombies.constant.Config; import com.su.botanywarzombies.model.BaseModel; import com.su.botanywarzombies.model.TouchAble;public class SeedPea extends BaseModel implements TouchAble {public SeedPea(int locationX, int locationY) {this.locationX = locationX;this.locationY = locationY;this.isLive = true;}@Overridepublic void drawSelf(Canvas canvas, Paint paint) {if (isLive) {canvas.drawBitmap(Config.seedPea, locationX, locationY, paint);}}@Overridepublic void onTouch() {}}

3.3 卡片對(duì)象的圖片加載，這里需要指定寬高

除以 6 是寬度的估算

int seedPicWidth = Config.seekBank.getWidth() / 6;int seedPicHeight = Config.seekBank.getHeight();Config.seedFlower = DeviceTools.resizeBitmap(BitmapFactory.decodeResource(getResources(), R.drawable.seed_flower), seedPicWidth, seedPicHeight);Config.seedPea = DeviceTools.resizeBitmap(BitmapFactory.decodeResource(getResources(), R.drawable.seed_pea), seedPicWidth, seedPicHeight);
