[Open / Signup] One Room Round Robin 3 - Calling All Modders

[minmay]

Oh the aliased Euclidean circle shape was intended then! Is it a problem?

It is, because it means the range of zone effects is effectively longer on diagonals than in compass directions (although the problem does not appear until ranges greater than 2 are used).

[AndakRainor]

Would you say this geometry should be used for a spell such as Oracle? (It hudPrints the distance from the party to nearby secrets in its range). For damage zone effects, monsters on diagonals will take more time to reach the party... But this geometry is not very natural, I would say tile based movements do not need additional taxicab features. arcane_nova would feel weird with this. I can't think about a situation where euclidean range would feel as weird as taxicab.

[minmay]

Would you say this geometry should be used for a spell such as Oracle? (It hudPrints the distance from the party to nearby secrets in its range).

No idea. Oracle is a strange spell in the first place because secrets are often not placed in the same location as whatever triggers them, for example all the secrets in Xanathar's room are inside walls. I think I'll just drop this issue.

[AndakRainor]

Good point. It could detect secret buttons instead, what do you think about that? (or do you plan on using third eye in the mod?)

[AndakRainor]

work in progress: down to 63 total spells...

I don't plan to include the Third Eye, though of course someone else can if they want to. (If someone else does add it, they should use the current version of third_eye.lua in this spoiler:)

[Isaac]

Good point. It could detect secret buttons instead, what do you think about that? (or do you plan on using third eye in the mod?)

Secrets are also scripted; as when the correct item is placed upon the altar... I think to really work, the spell would require a dedicated listing of what secrets it can detect in the specific dungeon [mod] where it is used. The list [table] could include the location of the secret, and a suitable '8-ball' style cryptic hint ~specific to the secret.

In "Lands of Lore", party members could spot a secret, and mention it aloud. The same could be done for the casting mage; perhaps even have a duration of effect, where the mage makes comments if they pass near a detectable secret. [Comments, but not the outright answer.]

[AndakRainor]

Can I remove hailstorm?

[minmay]

Yes, definitely. Cut any spells you want.

[AndakRainor]

I have a list of 49 spells now, versus 20 in Isle of Nex. Do you want me to continue?
