下午好。乍一看，这个问题似乎已经回答了，但我无法用我找到的答案解决我的问题。

我有一个类，其中一个函数应该调用另一个函数（传递“self”网格有参数），这就是问题所在，我在某处丢失了引用，我找不到在哪里。

这是代码，在此先感谢:)

//classe unit.
function unit(unitId, mesh, unitName, shieldSize, armor, armorTechLvl, shieldTechLvl, employeesNeeded, description, imageFilePath, structureNeeded, storageSize, unitSpeed, attackPower, weaponTech) {

更改unit.prototype.setMesh(...)为this.setMesh(...)。然后阅读原型继承。
