Any chance for Noodle's method of creating new xp requirements for levels? That is, instead of multiplying the original amount by a multiplier, just adding a base amount of xp to the total?
Not as fun as exponential xp requirements, but I like clean, rounded numbers myself.
EDIT: Might as well add some more comments here...
Big issue:
Using the levelmod.xp.hurt.sdkhooks.smx will cause a cacophony of errors in console (for the server), as well as somehow disable world damage (saw blades and bottomless pits I tested personally, may include payload explosions and trains). The deprecated plugin works without a flaw, though.
Suggestions:
Experience for assists and medic assists would be nice, though not necessary.
Setting "sm_lm_exp_maxbydmg" to zero disables experience through damage, instead of removing the experience ceiling ("0 = unlimited").
Disabling the level up sound with the particle effects would be nice if paired up.
Capping flags/pushing kart for experience? Didn't check it myself, but hey.
Possibly a chat message at the end of the game proclaiming the player with the highest level? (to be added to the "leader" core, of course).
It seems like "sm_lm_deathmessage" and "sm_lm_announce" have be remove/renamed as of 0.4. Any chance to get these back?
I understand that I'm not using the absolutely latest version, so you've probably gotten a lot more done since this one.
Enough suggestions for now, though... Everything else runs beautifully. It's a ton of fun to fight for the top level and gloat after you kill someone! Keep it up, man. I'll be testing this on my server for the time being.
