Cannon should launch throwables, like tridents, as thrown projectiles. The cannon can launch arrows and modded projectiles, including the throwable bricks that Supplementaries adds. This feature should be extended to tridents and other such weapons like spears. An interesting note is that Quark's pickarang is thrown by the cannon, and the dispenser does not do this, so maybe look into that.

cannon can launch all projectiles that can be thrown, it actually simulates player click. what sets trident apart is that they are not an instant throable so cannon tries to throw them but fails so shoots the item. I plan on adding that but it needs to wor with loyalty so that's why it hasnt been done yet
