Volrathxp's Custom Dotp 2014 DLC (Last Update: 12/6/2014)

So here's where I'm at with Sultai Ascendancy...

I can't figure out how to get it to only let me select 1 or none, it forces me to select 2.

I am blerged on this one.

Well, I just tested it with your Abzan deck. It didn't do anything. No creatures destroyed.

Odd. I built a deck specifically for this card and tested it extensively, and it worked every time.

Edit: Just tested it again, worked perfectly. Reupdate your decks/core, methinks.

Updated again, and now it worked. Very strange

[NeoAnderson]

The follow card Avalanche Tusker is not coded properly, as you coded it works only if you are attacking only with Avalanche Tusker.

Well, I will update at some point this week. Currently on a holding pattern for my wife to go to the hospital for the birth of our firstborn.

So I will have time off this week if she decides to come this weekend.

Huh? I'm confused by what you mean here.

I mean that looking your code you are simply forcing one target creature to block a creature.
This card says "Whenever Avalanche tusker attacks, target creature defending player controls blocks it this combat if able", it means that target creature must block Avalanche tusker!!!

2. There is another issue about this card Anafenza, the Foremost, you can put the +1/+1 counter on "another target tapped creature" so it shouldn't be able to target iself.

[thefiremind]

"Whenever Avalanche Tusker attacks, target creature defending player controls blocks it this combat if able"

Unfortunately there's no way to code "Creature A blocks creature B if able" in DotP2014. It seems to be possible in DotP2015 judging by a function in the engine, but that doesn't help.

This is not true my dear friend i already done it for a card into my BORN OF THE GODS SET. I coded a full work Vortex Elemental.

This solution is not straight or elegant, and it could have some small issues but is a good approximation.

[RiiakShiNal]

Your Vortex Elemental doesn't allow for the possibility that the creature can't block Vortex Elemental, but could block something else. For example Vortex Elemental targets an enemy Cloud Sprite and you attack with Vortex Elemental and a Cloud Elemental the enemy Cloud Sprite should be able to block the Cloud Elemental even though it can't block the Vortex Elemental. Your version doesn't allow that possibility. This is one of those cases that can pop up frequently which is why thefiremind and I keep saying that we can't code "Creature A must block Creature B if able". Additionally, there is the possibility that they don't want to block at all. If Vortex Elemental targets a Cloud Sprite and the Cloud Sprite can't block the Vortex Elemental (due to Vortex Elemental not having flying) then the opponent should also be able to say the Cloud Sprite isn't going to block anything because it isn't able to block the creature it "must" block. So that is two cases that it fails with just 1 set of cards.

[volrathxp]

I'm just going to yank the Tusker then, if it can't be done properly. No worries.

[Sebs92]

A correction to one of my previous posts. After further testing with Savage Knuckleblade it appears that the blue activated ability works just fine. It's the red and green abilities that do nothing when activated.

I haven't gotten around to testing this guy yet, so when I can get the time I will.

I know about this kind of issue, and i was thinking if there is a way to avoid it happens. Maybe if we concatenate 2 different delayed triggers and check if the creature is really blocking or not the assigned creature, if not we could ask to the player if want to block something else. But i am not sure if we have the needed timing to do that before the Blockers declared is finished.
