I guess that's cool but you would have to have the powerup right there to blink... be cooler if you could do it at any point. And honestly I've got an idea how that might work. Invisible switch that follows you (or a secret switch). The rest is whatever he already did. Bam, switch ability. Of course to follow you it would actually follow the weapon you picked up but this discovery will have many uses!!
Yeah the only think i cant figure out is that can you script teleporter to turn on and off or switch channels
Probably has it also following him, despawning and respawning. The one you see there is definitely the receiver node. Well probably
