見縫插針

本人只是看了老師的大綱,中途不明白不會的時候再去看的視頻
所以代碼可能與老師代碼有出入

UI腳本

import { _decorator, Camera, color, Component, director, instantiate, Label, math, Node, Prefab, tween } from 'cc';
const { ccclass, property } = _decorator;@ccclass('ts_ui')

}

針腳本

import { _decorator, Collider2D, Component, Contact2DType, Input, input, Node } from 'cc';
import { ts_circle } from './ts_circle';
import { ts_ui } from './ts_ui';
const { ccclass, property } = _decorator;@ccclass('ts_pin_s')
export class ts_pin_s extends Component {move_sp : number = -2   //  -2剛生成時 -1等待發(fā)射 0發(fā)射 1完成碰撞start() {const col = this.getComponent(Collider2D)if (col){col.on(Contact2DType.BEGIN_CONTACT,this.on_bc,this)}   //  開啟碰撞else {console.log(`針頭 開啟碰撞異常`)}input.on(Input.EventType.TOUCH_END , this.on_te , this)     //  開啟觸摸}on_bc (me : Collider2D , oth : Collider2D){console.log(`針頭碰撞`,oth.name)if (oth.name == `Circle<CircleCollider2D>`){const pw = this.node.getWorldPosition()const rw = this.node.getWorldRotation()const cir = ts_circle.getinthis()this.node.setParent(cir.node)       //  更新父節(jié)點this.node.setWorldPosition(pw)this.node.setWorldRotation(rw)this.move_sp = 1const ui = ts_ui.getinthis()ui.pin_num = 0ui.on_fen(1)}if (oth.name == `Pin<BoxCollider2D>`){ts_ui.getinthis().on_end()}}on_te(){if (this.move_sp == -1){this.move_sp = 0}}update(deltaTime: number) {this.move(deltaTime)}move(deltaTime: number){if (this.move_sp >= 1){return}const pos = this.node.getPosition()if (this.move_sp == -2){if (pos.y <= -500){this.node.setPosition(pos.x , pos.y + deltaTime * 500)}      //  新生成速度else {this.move_sp = -1}}if (this.move_sp == -1){return}if (this.move_sp == 0){this.node.setPosition(pos.x , pos.y + deltaTime * 1000)}      //  發(fā)射速度}
}

move 函數(shù)處于性能考慮
應該在條件判斷成立時 返回的,不應該多個IF輪流判定

球腳本

import { _decorator, CircleCollider2D, Collider2D, Component, Contact2DType, Input, Node } from 'cc';
const { ccclass, property } = _decorator;@ccclass('ts_circle')
export class ts_circle extends Component {static inthis : ts_circlestatic getinthis() : ts_circle {return this.inthis}start() {ts_circle.inthis = thisconst col = this.getComponent(Collider2D)if (col){col.on(Contact2DType.BEGIN_CONTACT,this.on_bc,this)}else {console.log(`球 開啟碰撞異常`)}}on_bc(me : Node , oth : Node){console.log(`球 碰撞` , oth.name)}update(deltaTime: number) {this.node.angle += 2if (this.node.angle >= 360){this.node.angle = 0}}
}

心得_旋轉(zhuǎn)

項目設置 > 功能裁剪 > 2D物理系統(tǒng) > 內(nèi)置2D物理系統(tǒng)
在不改內(nèi)置的情況下

this.node.angle += 2    //  旋轉(zhuǎn)角度速度

球旋轉(zhuǎn)會卡住不動,取消剛體組件也可以使其正常旋轉(zhuǎn),但碰撞就會有點麻煩

心得_更改父節(jié)點

在變更父節(jié)點的時候,子節(jié)點的位置和角度會被重置
不想重置,就需要記錄之前的位置和角度,更換后再設置回來

        if (oth.name == `Circle<CircleCollider2D>`){const pw = this.node.getWorldPosition()const rw = this.node.getWorldRotation()const cir = ts_circle.getinthis()this.node.setParent(cir.node)       //  更新父節(jié)點this.node.setWorldPosition(pw)this.node.setWorldRotation(rw)this.move_sp = 1const ui = ts_ui.getinthis()ui.pin_num = 0ui.on_fen(1)}

心得_緩動動畫

還沒有仔細研究,看了老師的視頻,依葫蘆畫瓢
但看使用情況來看,以下是個人理解
tween 傳入緩動組件
to 傳入 1緩動執(zhí)行時間 2組件需要緩動變更的屬性
start 開始

    on_anim(){  //  結(jié)束緩動動畫函數(shù)let new_col = new math.Color()new_col.r = 60new_col.g = 5new_col.b = 5new_col.a = 255tween(this.camera).to(1 , {orthoHeight : 450 , clearColor : new_col}).start()}
