00003不思议迷宫.0009.5：炼金坊自动捡钱

      在前面的文章中曾接触过炼金坊方面的代码。这次我要给炼金坊增加自动捡钱功能，那些研究研究经验刚好可以派上用场。

      炼金炉喷出金子的函数是UINewWorkshop:produceGold(count)。

      玩家捡取金币的代码，还是得从触摸事件找起：

--注册点击处理回调

functionUINewWorkshop:registerTouchCallBack()

   ……

   --背景图点击回调

   local bg = findChildByName(self.node,"bg");

   bg:addTouchEventListener(function(sender,eventType)

       if eventType ==ccui.TouchEventType.began then

           local beganPos =sender:getTouchBeganPosition();

           self.lastMovePos = sender:getTouchBeganPosition();

           self:tryPickupGold(beganPos);

       elseif eventType ==ccui.TouchEventType.moved then

           local movePos =sender:getTouchMovePosition();

           self.lastMovePos = sender:getTouchBeganPosition();

           self:tryPickupGold(movePos);

       end

   end);

   ……

end

      self:tryPickupGold(beganPos)，就它了。找到之后呢，只要把它在UINewWorkshop:produceGold(count)中进行调用就好了：

--炼金炉喷出金子

functionUINewWorkshop:produceGold(count)

   ……

   local goldNode = findChildByName(self.node,"bg/gold_node");

   local goldParentNode =findChildByName(self.node, "bg");

 

   for i = 1, count do

       local newGold = goldNode:clone();

       newGold:setVisible(true);

       local gold =newGold:getChildByName("gold");

       gold:setVisible(true);

       local shadow =newGold:getChildByName("shadow");

 

       local targetNode = self:getFreePos();

       if targetNode == nil then

           -- 没有空闲位置，就不产了

           return;

       end

 

       local targetPos =cc.p(targetNode:getPosition());

 

       targetNode.isUsed = true;

 

       local jumpTo1 = cc.JumpTo:create(0.2,cc.pAdd(targetPos, targetNode.offset2), 50, 1);

       local jumpTo2 = cc.JumpTo:create(0.1,cc.pAdd(targetPos, targetNode.offset1), 10, 1);

       local jumpTo3 = cc.JumpTo:create(0.1,targetPos, 5, 1);

       local callFunc =cc.CallFunc:create(function()

           goldParentNode:removeChild(newGold);

           newGold:setPosition(0, 0);

 

           shadow:setVisible(true);

 

           -- 到目标节点后，从底图删除，挂在目标节点上

           targetNode:removeAllChildren();

           targetNode:addChild(newGold);

           targetNode:setVisible(true);

 

           local function showGoldEffect()

               local effect;

               local callFunc1 =cc.CallFunc:create(function()

                   local gold =newGold:getChildByName("gold");

                   gold:setOpacity(10);

                   shadow:setOpacity(0);

 

                   -- 播放金币闪过的动画

                   _, effect =playEffect(newGold, 1161, 2, -13);

               end);

               local delay = cc.DelayTime:create(1);

               local callFunc2 =cc.CallFunc:create(function()

                   newGold:removeChild(effect);

 

                   -- 动画播放完毕，金币图标出现

                   gold:setOpacity(255);

                   shadow:setOpacity(255);

 

                   performWithDelay(newGold,showGoldEffect, math.random(3, 10));

               end);

               newGold:runAction(cc.Sequence:create(callFunc1, delay, callFunc2));

           end

           showGoldEffect();

 

           -- 第一块金币，引导玩家去捡

           if self.waitForClick == nil then

               self.waitForClick = true;

               local hand =newGold:getChildByName("hand");

               hand:setVisible(true);

               hand:setLocalZOrder(1000);

               playClickEffect(hand);

           end

 

           -- 一次喷两个金币，引导玩家拖动

           if self.showDragEffect and i == 1then

               self.showDragEffect = false;

               self.waitForClick = true;

               local hand =newGold:getChildByName("hand");

               hand:removeAllChildren();

               playDragEffect(hand);

           end

 

self:tryPickupGold(targetPos);

       end);

 

       newGold:runAction(cc.Sequence:create(jumpTo1, jumpTo2, jumpTo3,callFunc));

       --先在底图上飞

       goldParentNode:addChild(newGold);

   end

 

   if self.lastCount == 1 and count == 2 then

       self.showDragEffect = true;

   end

 

   self.lastCount = count;

end

      这么改之后发现居然有bug，那就换一种方法。喷射金币是一个定时循环操作，我们只要在这个定时中不停地tryPickupGold就行。这个定时循环在UINewWorkshop:startProduce()中定义：

--炼金炉开始工作

functionUINewWorkshop:startProduce()

   ……

 

   -- 金币位置列表

   self.goldPosList = {};

   for i = 1, 20 do

       local posNode =findChildByName(self.node, "bg/pos_parent/pos"..i);

       local jump2Node =posNode:getChildByName("jump2");

       local jump1Node =posNode:getChildByName("jump1");

       posNode.offset1 =cc.p(jump1Node:getPosition());

       posNode.offset2 =cc.p(jump2Node:getPosition());

 

       posNode:setLocalZOrder(math.floor(-posNode:getPositionY()));

       table.insert(self.goldPosList,posNode);

   end

 

   ……

 

   -- 炼金

   local function start()

       if self.waitForClick orself:getFreePos() == nil or self.isHighlightWorkshopBubble

           or (notAlchemyWorkshopM.isAllGuideFinished() and bubble:isVisible()) then

           produceNode:removeAllChildren();

           performWithDelay(self, start, 0.5);

           return;

       end

 

       furnaceIcon:setVisible(false);

 

       -- 喷金币

       produceNode:removeAllChildren();

       playEffect(produceNode, 1173, 88, -53);

 

--       performWithDelay(produceNode,function() AudioM.playFx("workshop_furnance"); end, 0.1);

--       performWithDelay(produceNode,function() AudioM.playFx("workshop_produce"); end, 2.3);

 

       local function produce()

           furnaceIcon:setVisible(true);

 

           local produceCountEachTime =FormulaM.invoke("GET_GOLD_PRODUCE_AMOUNT");

           self:produceGold(produceCountEachTime);

 

           performWithDelay(self, start, 0.6);

       end

       performWithDelay(self, produce, 2);

 

             for_, node in pairs(self.goldPosList) do

                   local targetPos =cc.p(node:getPosition());

                   self:tryPickupGold(targetPos);

             end

   end

 

   start();

end

      居然还是有问题，最左边的两个金币无法捡取，不过倒也可以接受了，就这样吧。
