Don't Know.
But OnTopic:
Yes, you could do this very easily with VCE, but it wouldn't be automatic, unless you only had one person on the server. But anyways, yes it is possible so that if you have 7 kills and you click a brick in the spawn room you could collect your rewards
for the brick loading thing, it is possible to download too many add-ons so that you have to many datablocks. this would cause some add-ons, such as bricks, to not appear in your brick menu, thus they woudnt load.
on topic.
clicking a brick for killstreak is possible, but if you want it more streamline, you could use onminigamekill event, from minigame events by destiny. this in combo with vce allows you to do some pretty flawless stuff.
for killstreaks, use onminigamekill-killer(client)-modvariable-[Playerkillstreak] [add] [1]
then, everytime there is a kill, that player gets a killstreak point added. another event is needed to check to see if that player has enough poits for a reward, it would go something like--
1
- onminigamekill-killer(client)-ifvariable-[playerkillstreak] [==] [3] [2-3]
2
- onvariabletrue-player-additem-gun
3
- onvariablefalse-client-ifvariable-[playerkillstreak] [==] [5] [4-5]
4
- onvariabletrue-player-additem-sniper rifle
5
- onvariablefalse-client-ifvariable-[playerkillstreak] [==] [10] [6-6]
6
- onvariabletrue-player-additem-mininuke
items were just an example, you can also add messages and soubds whenever a kill streak reward is given.
long post, sorry.
also, i have never in my life tried to do killstreak stuff so im not all that sure this would work, but theoretically it should.
