Partially based on CCX's creative minigame maps we are including some new traps in 1.30, a KeyBinder Trap and a Particle Spawn trap.
KeyBinder Trap - Can be configured to trigger when the player presses a key.
ParticleSpawn Trap - When activated it will spawn a particle (Fire/Ice currently) with your preset velocity.
Another possible trap would be the CreateTrap Trap to dynamically generate traps during a level. If you've used the editor please let me know what else might be useful as a level designer to create more exciting maps.
I will post an example level using these two objects after 1.30 is out.
