What about TCreator?

You can make terraria mods there. From making tiles to making very OP swords with projectile spam.

-create tile(block)

-create tool

-create ranged weapon

-create crafting table

-create recipe

-create item

-create sword projectile

-create entity, mob or boss

and much more!

in tile and crafting table creator you can select size in tiles, effects(rope effect, hellstone effect, platform effect and more)

in tool editor you can select type of tool(sword, axe, pickaxe, hammer, multitool). You can also select projectiles for them on swing(if you make these) using procedures. you can select tool power(if sword its hidden)

in ranged weapon you can select type(throwing weapon, melee throwing weapon, ranged weapon, magic weapon). its like editor from mcreator, but there no item check. If you select throwing weapon, you can check, if item consumes when it used. If you select melee throwing weapon, this will be non-consumable melee ranged weapon. If you select magic weapon, you can set mana consume.

in recipe editor you can make recipes for items. Like if you select  [item] as result, you can add materials like (20 wood, 10 stone, 1 copper shortsword). Also you need check for crafting table([anvil] or higher)

item editor is same.

in sword projectile editor you can select type(blade, rain and more). You can bind those projectiles for item using procedures. You can bind more than one projectiles for item.

In entity editor... Omg, its hard to explain. Its going be same like scratch.mit.edu editor.

And procedures blocks:

-Shoot projectile on swing/use

-Shoot projectile on consume

-Set effect (effect) on current entity with duration (duration in seconds)

-Bounce when hits wall (if its ranged weapon or projectile).

I think its all
