Why?
 

why will this not work to give me a flame going up if player faces that way or down if player faces that way?

if (weaponfired&&playermp>9&&playerdir=up){playermp-=10;
xAxisPos = 4;
while (xAxisPos < 20) {
blast1();
if (xAxisPos != 19) {
sleep 0.05;
}
xAxisPos++
}
}

function blast1() {
putexplosion2 2,1,playerx+0.7,playery-xAxisPos;
}

if (weaponfired&&playermp>9&&playerdir=right){playerm p-=10;
xAxisPos = 4;
while (xAxisPos < 20) {
blast2();
if (xAxisPos != 19) {
sleep 0.05;
}
xAxisPos++
}
}

function blast2() {
putexplosion2 2,1,playerx-xAxisPos,playery;
}

NPC Code:

---

if(weaponfired && playermp >=10){

  if(playerdir==0 || playerdir==2){

    playermp-=10;

    this.dir=playerdir;

    this.distance=0;

    this.startxy={playerx+vecx(this.dir)*2,playery+vec  y(this.dir)*2};

    timeout=.05;

  }

}



if(timeout){

  if(this.distance < 20){

    this.distance++;

    putexplosion2 2,1,this.startxy[0],this.startxy[1];

    this.startxy[0]+=vecx(this.dir);

    this.startxy[1]+=vecy(this.dir);

    timeout=.05;

  }

}

not tested, but it should work...

playerdir=up
WRONG
numerical values 0,1,2 and 3
