Hi Yall, just wrote some script for a NPC to throw a dart every few seconds, which should be happening in the background without any eBlock but something is causing one to happen (which would ruin the scene)

heres the code:


function room_Load()
{
  oThrowDart.Transparency = 100;
SetTimer(1, 280);
}


function room_RepExec()
{
if (IsTimerExpired(1)){
  int RandoDart;
cTurtle.Animate(1, 50, eOnce, eNoBlock);
Wait(140);
oThrowDart.Transparency =0;
RandoDart = Random(2);
  if (RandoDart == 0) oThrowDart.Move(-100, 155, 8, eNoBlock, eAnywhere);
  if (RandoDart == 1) oThrowDart.Move(-100, 240, 8, eNoBlock, eAnywhere);
  if (RandoDart == 2) oThrowDart.Move(-100, 350, 8, eNoBlock, eAnywhere);
  Wait(80);
  oThrowDart.Transparency=100;
  oThrowDart.Move(614, 480, 10, eNoBlock, eAnywhere);
Wait(80);
cTurtle.Animate(8, 50, eOnce, eNoBlock);
SetTimer(1, 280);
  }
}

which as you can see from cTurtle.Animate(1, 50, eOnce, eNoBlock); until cTurtle.Animate(8, 50, eOnce, eNoBlock); blocks player actions despite putting eNoBlock's all over the place.

is there any way around this?

thanks in advanace!

Waits are blocking and timers are rather fragile. Try a room variable instead (untested):


int turn;

function room_RepExec()
{
int RandoDart;

turn++;
if(turn == 280)
cTurtle.Animate(1, 50, eOnce, eNoBlock);
else
if(turn == 420)
{
oThrowDart.Transparency = 0;
RandoDart = Random(2);
if(RandoDart == 0) oThrowDart.Move(-100, 155, 8, eNoBlock, eAnywhere);
if(RandoDart == 1) oThrowDart.Move(-100, 240, 8, eNoBlock, eAnywhere);
if(RandoDart == 2) oThrowDart.Move(-100, 350, 8, eNoBlock, eAnywhere);
}
else
if(turn == 500)
{
oThrowDart.Transparency = 100;
oThrowDart.Move(614, 480, 10, eNoBlock, eAnywhere);
}
else
if(turn == 580)
{
cTurtle.Animate(8, 50, eOnce, eNoBlock);
turn = 0;
}
}

A note should be made that calculating loops will make it depend on game speed settings.

I thought timers and waits were already dependent on game speed settings.

Yes... really. I forgot they take game loops for delay too.

For a real timer you would need to use DateTime class.

works perfectly. i'll use room variables in future.

thanks very much!

AGS can't do anything faster than 1 game frame (game logic loop and drawing loop are tied together ATM), so actually GetGameSpeed is the most accurate for cases like this. You could approximate milliseconds by doing:

int GetApproxMSInGameLoops(int targetMS, RoundDirection dir) // dir default is eRoundNearest
{
  float fresult = (IntToFloat(targetMS) / IntToFloat(GetGameSpeed())) / 1000.0; // (ms*40)/1000 for default game speed
  return FloatToInt(fresult, dir);
}

Of course a larger increment of time can be exactly precise (seconds = X * GetGameSpeed(), etc.).
