【plang 1.4.4】编写茶几玛丽脚本

本着测试plang语言工具健壮性的初衷，再次打起了写小游戏的念头。但是一想到是用命令行作为显示端，就觉得头皮发麻。

今天做的叫做茶几玛丽（四不像），还是硬着头皮上代码。

先设计玛丽类：

package mario;
import std::IO;
import std::Type;

import std::TIME;

public class Mario : GameObject
{
	public Mario()
	{
		super();
	}

	public update()
	{
		gui.draw(x+offX, y+offY, 'm');
	}

	public update(x->int, y->int)->boolean
	{
		if(run)
		{
			time->long = TIME.clock();
			t->float = (time-lastTime) * 0.001;
			v0->float = -20;
			offY = v0 * t + 20 * t * t;
			offX += x==0 ? 0f : (x<0 ? -0.5f : 0.5f);

			if(offY >0) 
			{
				lastTime = TIME.clock();
				run = false;
			}
		}
		return run;
	}

	public reset()
	{
		lastTime = TIME.clock();
		run = true;
	}

	public getX()->int
	{
		return x + offX;
	}

	public getY()->int
	{
		return y + offY;
	}

	x->int = 5;
	y->int = 10;
	offX->float = 0;
	offY->float = 0;
	run->boolean = false;
	lastTime->long = TIME.clock();
}

再设计蘑菇类：

package mario;

public class MushRoom : GameObject
{
	public MushRoom()
	{
		super();
	}

	public update()
	{
		gui.draw(x + offX, y,'#');
	}

	public update(x->int, y->int)->boolean
	{
		if(run)
		{
			offX += 1;
			if(offX > 20) run = false;
		}
		else
		{
			offX -= 1;
			if(offX < -20) run = true;
		}

		return false;
	}

	public getX()->int
	{
		return x + offX;
	}

	public getY()->int
	{
		return y;
	}

	x->int = 20;
	y->int = 10;
	run->boolean = true;
	offX->float = 0;
}

万事俱备，只欠场景类。动起来。。

import std::IO;
import std::Type;

import mario::Mario;
import mario::MushRoom;
import std::IOEXT;
import std::OS;

public class Main
{
	public static main()
	{
		m->Mario = new Mario();
		n->MushRoom = new MushRoom();

		L->int = 0;
		R->int = 50;
		
		T->int = 0;
		B->int = 20;
		
		offX->int = 1;
		offY->int = 0;

		while(true)
		{
			OS.system("cls");

			a->int = IOEXT.key('A');
			d->int = IOEXT.key('D');
			w->int = IOEXT.key('W');
			s->int = IOEXT.key('S');
			q->int = IOEXT.key('Q');

			if(q != 0)
			{
				break;
			}

			if(a != 0 && d != 0)
			{
				;
			}
			else if(a != 0)
			{
				offX = -1;
				m.reset();
			}
			else if(d != 0)
			{
				offX = 1;
				m.reset();
			}
			
			if(offX != 0)
			{
				if(m.update(offX, offY) == false)
				{
					offX = 0;
				}
			}
			
			if(n.getX() == m.getX() && n.getY() == m.getY())
			{
				break;
			}
			n.update(0,0);

			m.update();
			n.update();
			co_yield null;
		}

		IO.printf("game over!");
	}
}
