Important: I just realized that the fix to Reiver Demon will probably lead to problems later on. The problem is this: Reiver Demon has an ability "When yu play this from your hand ...". This was coded as @moveto(this|mybattlefield) from(mayhand). Which doesn't work, because the card doesn't actually enter the battlefield from the hand, it enters from the stack. So, "@moveto(this|mybattlefield) from(maystack)" has the desired effect. However, IIUC, spells played from anywhere else (e.g. from the graveyard, if they allow that) should be placed on the stack to. Hence, the "fixed" trigger will also fire in this case, which is wrong.
This means that we can't actually code "played from ..." entirely correct at the moment. Is there a solution for this?
According to the rules, only a copy of a spell enters the stack (never the spell itself), so could the "from()" part access where the card actually came from?
Do we need an @played trigger to differentiate between moving a card and actually playing it?
Notes to programmers:
1. This feature uses an awful lot of copy-pasta, using "protetcion from()" as a base. While I'm learning the architecture, it's easier for me to have a dedicated single-purpose piece of code to work with, than trying to create multi-purpose code. I'm aware that this isn't a very elegant approach though, and I hope to be able to refactor additions like this into multi-purpose code once I have a better understanding of the architecture as a whole.
2. Please check the questions I'll add in my next code comments, specifically about AI integration and activated abilities / instants / sorceries.
3. I did have a crash (with the debugger complaining about stack corruption around the cd variable) during testing. I wasn't able to reproduce it though. I did have to clean the solution in-between when I updated to the primitives system, so perhaps there was this cleaning solved whatever corruption was in my files. I'm mentioning the issue in case someone has an idea on where my code might be risky (I'm still probne to making beginners mistakes).
Thanks to TheDark for the bug report on Urza's lands.
Note that the lands still don't work entirely correct, they give you the option to tap them for one mana even when they shouldn't anymore. This can be fixed when aslongas(cards) <1 is working.
- Card Primitives system. Check Royal Assassin in RV, 10E, M10
- Please review, is sets/primitives a good directory? Should we rename MTGCard into "CardPrint"?
- Unfortunately for now it is not possible to "override" a Primitive. A card that links to a primitive but also defines new "values" will create its own data and ignore the data in the "linked" primitive for the time being. I hope to solve that at some point...
Limitations:
- Operators for "greater than", "less than", "unequal" have not been implemented, but if a card actually needs them, you can use a preceding minus sign to negate a comparison. Example: -power=3 means "power not equal to 3", -toughness<=3 means "toughness>3".
- You can't use spaces when specifying such restrictions. Write "power<=3" instead of "power <= 3"
- You now need to use a space before the "<" and ">" commands that count the matches for lord(), foreach(), all() and aslongas(). So far we always did use spaces in front of them without actually needing to, now we need to.
- manacost restrictions don't take "X" costs into account. Example: Mistmeadow Skulkin (FUT) has protection from manacost>=3. Blaze has a converted manacost of 1, but when you cast it with an X of 2, then it actually has a converted manacost of 3 while on the stack, and Mistmeadow Skulkin would be protected from it, but currently it isn't.
Please review the code, I'll add a few remarks/questions of my own.
Now: auto=@movedTo(this|graveyard,library,hand,exile) from(battlefield) ...
Alternatives:
auto=@movedFrom(this|battlefield) ...
auto=@movedTo(this|*) from(battlefield) ...
auto=@movedTo(this|-battlefield) from(battlefield) ...
Suggestions? How many cards would benefit from such an addition?
