Hello!

I'm making a spell which reflects projectiles that hits the target in front of him. This is what I've got (with udg_Caster being the projectile and udg_Target being the target):

Trigger:
  • Defend Reflect
    • Events
    • Conditions
    • Actions
      • Set Point[10] = (Position of Target)
      • Set Point[20] = (Position of Caster)
      • Set Real[10] = (Angle from Point[1] to Point[2])
      • Set Real[20] = (Facing of Target)
      • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
        • If - Conditions
          • Real[10] Less than 0.00
        • Then - Actions
          • Set Real[10] = (Real[10] + 360.00)
        • Else - Actions
      • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
        • If - Conditions
          • And - All (Conditions) are true
            • Conditions
              • And - All (Conditions) are true
                • Conditions
                  • Real[1] Greater than or equal to (Real[20] - 90.00)
                  • Real[1] Less than or equal to (Real[20] + 90.00)
        • Then - Actions
        • Else - Actions
          • Game - Display to (All players) the text: xxx
      • Custom script: call RemoveLocation (udg_Point[10])
      • Custom script: call RemoveLocation (udg_Point[20])


The problem now is that the message is always displayed despite if the missile hits the target in front of the target or behind the target. What am I doing wrong here?

I do believe you're using the wrong point variables. You're setting Point[10] and Point[20], yet you use Point[1] and Point[2] to set your impact angle.

Ah, that was a simple mistake. Well now it reflects the projectile some times, but some times it doesn't (doesn't seem to depend on wether the projectile comes in front of the unit or from behind):

Trigger:
  • Defend Reflect
    • Events
    • Conditions
    • Actions
      • Set Point[10] = (Position of Target)
      • Set Point[20] = (Position of Caster)
      • Set Real[10] = (Angle from Point[10] to Point[20])
      • Set Real[20] = (Facing of Target)
      • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
        • If - Conditions
          • Real[10] Less than 0.00
        • Then - Actions
          • Set Real[10] = (Real[10] + 360.00)
        • Else - Actions
      • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
        • If - Conditions
          • And - All (Conditions) are true
            • Conditions
              • And - All (Conditions) are true
                • Conditions
                  • Real[10] Greater than or equal to (Real[20] - 90.00)
                  • Real[10] Less than or equal to (Real[20] + 90.00)
        • Then - Actions
          • Set Action = True
        • Else - Actions
          • Set Action = False
          • Special Effect - Create a special effect attached to the origin of Target using Abilities\Spells\Human\Defend\DefendCaster.mdl
          • Special Effect - Destroy (Last created special effect)
          • Game - Display to (All players) the text: c
          • Unit - Create 1 (Unit-type of Caster) for (Owner of Target) at Point[20] facing (Angle from Point[10] to Point[20]) degrees
          • Unit - Set the custom value of (Last created unit) to (Custom value of Caster)
          • Unit - Remove Caster from the game
          • Set Caster = (Last created unit)
          • Unit Group - Add Caster to Projectile_Group
          • Unit Group - Add Caster to HungeringArrow_Group

try not to use angles instead use areas in front and behind if the projectile enters the front area reflect if not don't [i don't make maps anymore so i can't help you with the targets ]

Your angel conditions are looking some kind of strange in general.
Trigger:
  • Set Real[10] = (Angle from Point[10] to Point[20])

would calculate the angel using a vector from the target to the projectile. And thats the wrong direction.
Your converting Real[10] from signed into unsigned. However, Real[20] remains signed.
Your calculating +/- 90 which would create wrong angels when Real[20] is > -90 / > 90. Reals are 32-bit floating point variables and the overflow occures at about 3.5e38 which is far far away.

i dont think the area idea is that good. It would require that you either have a static unit that can not move or that you constantly move those areas around which is... unneccesary.

This works fine for me.
Trigger:
  • Set TempPoint = (Position of (Triggering unit))
    • Set TempPoint2 = (Position of (Target unit of ability being cast))
    • Set TempReal = (Angle from TempPoint2 to TempPoint)
    • Set TempReal2 = (Facing of (Target unit of ability being cast))
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • TempReal Greater than or equal to (TempReal2 - 90.00)
        • TempReal Less than or equal to (TempReal2 + 90.00)
      • Then - Actions
        • Game - Display to (All players) the text: Impact was in front.
      • Else - Actions
        • Game - Display to (All players) the text: Impact was from behind.
    • call Clear()

Are you deflecting when Action = True or False?

Thanks for the support guys! Deflecting is when Action = True. This is what I got now, and seems like it always deflects now (?)

Trigger:
  • Defend Reflect
    • Events
    • Conditions
      • (Target is in Defend_Group) Equal to True
    • Actions
      • Set Point[10] = (Position of Target)

      • Set Real[10] = (Angle from Point[20] to Point[10])
      • Set Real[20] = (Facing of Target)
      • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
        • If - Conditions
          • Real[10] Greater than or equal to (Real[20] - 90.00)
          • Real[10] Less than or equal to (Real[20] + 90.00)

          • Unit - Remove Caster from the game
          • Set Caster = (Last created unit)

  • Varine Varine:
    I want to build a filtration system for my 3d printer, and that shit is so much more complicated than I thought it would be
  • Varine Varine:
    Apparently ABS emits styrene particulates which can be like .2 micrometers, which idk if the VOC detectors I have can even catch that
  • Varine Varine:
    Anyway I need to get some of those sensors and two air pressure sensors installed before an after the filters, which I need to figure out how to calculate the necessary pressure for and I have yet to find anything that tells me how to actually do that, just the cfm ratings
  • Varine Varine:
    And then I have to set up an arduino board to read those sensors, which I also don't know very much about but I have a whole bunch of crash course things for that
  • Varine Varine:
    These sensors are also a lot more than I thought they would be. Like 5 to 10 each, idk why but I assumed they would be like 2 dollars
  • Varine Varine:
    Another issue I'm learning is that a lot of the air quality sensors don't work at very high ambient temperatures. I'm planning on heating this enclosure to like 60C or so, and that's the upper limit of their functionality
  • Varine Varine:
    Although I don't know if I need to actually actively heat it or just let the plate and hotend bring the ambient temp to whatever it will, but even then I need to figure out an exfiltration for hot air. I think I kind of know what to do but it's still fucking confusing
  • The Helper The Helper:
    Maybe you could find some of that information from AC tech - like how they detect freon and such
  • Varine Varine:
    That's mostly what I've been looking at
  • Varine Varine:
    I don't think I'm dealing with quite the same pressures though, at the very least its a significantly smaller system. For the time being I'm just going to put together a quick scrubby box though and hope it works good enough to not make my house toxic
  • Varine Varine:
    I mean I don't use this enough to pose any significant danger I don't think, but I would still rather not be throwing styrene all over the air

  • The Helper The Helper:
    I do know this - xenforo dropped the ball by not keeping the vbulletin reputation comments as a feature. The loss of the Reputation comments data when we switched to Xenforo really was the death knell for the site when it came to all the users that left. I know I missed it so much and I got way less interested in the site when that feature was gone and I run the site.
