Undertale Tower Defense Script Fix May 2026

Undertale Tower Defense (UTTD) on Roblox, "scripts" typically fall into two categories: educational/game development scripts for those making their own games, and gameplay utility

• The "Sans" Tower (Cost: 9999 G): Does 1 damage per frame, but ignores invincibility frames (I-frames). Script: damage = 1; attack_rate = 1; if(target.hit == true) target.hurt(); (Note: Must be balanced with a 'Karma' debuff).
• The "Undyne" Tower: Throws spears in a line. Script: if distance_to_point(target.x, target.y) < 100 instance_create(self.x, self.y, obj_spear);
• The "Papyrus" Trap: Does zero damage but "Blue Attacks" the enemy, forcing them to stop moving if they are not jumping. Script: if target.moving == true target.speed = 0;

Next Steps

• CHARM (status): temporarily converts enemy to your side or pacifies.
• HEALER: restores soul HP or repairs broken towers.
• TRAP: ground tile that triggers on enemy cross.
• SHIELD: creates a temporary barrier on path to delay enemies.
