Chase Animation

[Agnetha]

Hey Guys I have a scene in my game where the player gets chased after collecting an item. This is the script so far I can get the crab to follow the player, but the animation plays straight away and the crab is still on the screen walking towards player while it plays.

function oObject0_Interact(Object *theObject, CursorMode mode)
{
    cEgo.Walk(oObject0.X, oObject0.Y, eBlock, eWalkableAreas);
    cEgo.LockView(EGOPICKUP);
    cEgo.Animate(0, 7, eOnce, eBlock);
    cEgo.UnlockView();

   
    oObject0.Visible = false;
    cEgo.AddInventory(iKey);
    Display("You have found the key!");

    // ////
    cCrabboss.PlaceOnWalkableArea();
    cCrabboss.FollowCharacter(cEgo, 5, true);
    cEgo.LockView(76);
    player.Animate(0, 7, eOnce, eBlock);
    Display("CrabBoss caught you!");

    }

In general it's helpful to change object names from Object0 to something like oPearl right after creating them; this will generate function names like oPearl_Interact, making the code more readable.

Anyway, the issue is that the crab catching the player is a separate event based on distance, so you need to move it to the room's repeatedly execute event.
Add the event in the room events pane; this will add the function to the end of the script.

Code: ags

  // end of function oObject0_Interact
  cCrabboss.FollowCharacter(cEgo, 5, true);
}

int DistanceFrom(this Character*, Character* other) {
  float dx = IntToFloat(other.x - this.x), dy = IntToFloat(other.y - this.y) * 1.5; // perspective correction
  return FloatToInt(Maths.Sqrt(dx * dx + dy * dy), eRoundNearest);
}

// generated function
function room_RepExec() {
  if (cCrabboss.Following == player && cCrabboss.DistanceFrom(player) < 20) {
    cCrabboss.FollowCharacter(null);
    cCrabboss.StopMoving();
    player.StopMoving();
    player.LockView(76);
    player.Animate(0, 7, eOnce, eBlock);
    Display("CrabBoss caught you!");
  }
}
