这段SDK代码哪儿错了

根据wudy的WSC & FVM 1.2 中的例子spring.c改编（我是c小白，说详细点）
#include "fxlib.h"
#define BALL_RADIUS 5
int mx, my, bx, by;
int key;
float vx, vy;
int AddIn_main(int isAppli, unsigned short OptionNum)

    Bdisp_AllClr_DDVRAM();
    mx = bx = 63; my = by = 10;
    vx = vy = 0;
while( 1 )
{
    float fx = mx - bx;
    float fy = my - by + 20;
    vx += (fx / 40);
    vy += (fy / 40);
    vx *= 0.98; vy *= 0.98;
    bx += vx; by += vy;
   allclr();
    fillcircle( bx, by, BALL_RADIUS );
    drawmouse( mx, my );
    drawline( mx, my, bx, by );
    putdisp();
    if( iskeydown( KEY_CTRL_UP ) )
      my -= 3;
    if( iskeydown( KEY_CTRL_DOWN ) )
      my += 3;

    if( iskeydown( KEY_CTRL_RIGHT) )
      mx += 3;
    if( iskeydown( KEY_CTRL_EXIT ) )
      break;
    sleep( 30 );
}
   return 1;
}

void drawmouse( int x, int y )
{
drawline( x-1, y, x+1, y );
drawline( x, y-1, x, y+1 );
}
好像似这错了

rphero 发表于 2012-9-1 15:55:57

我建议你先看看最最基本的sdk教程，你这些函数，allclr()，drawline()什么的在sdk里都叫什么

ereeer 发表于 2012-9-1 16:01:34

我知道，我已把 fxlib.h翻了个底朝天，我原是学vb的，一些东西大致能懂

编译成功，但是实验时怎么一片空白、

我都逐字检查过了，为什么还是空白

成功了， 原来忘记加mathf.h了

imath 发表于 2012-9-1 17:41:44

Bdisp_DrawlLneVRAM应该改成Bdsisp.DrawlLneVRAM
