The HUD (Heads-Up Display) is a key element in Yandere Simulator as it presents information in-game.
If Yandere-chan is acting strange or engaging in an activity that can be seen as suspicious, strange, or downright rude, a warning message will appear at the top center of the screen. Multiple messages can stack up at once, although they disappear over time.
Near a Corpse
If Yandere-chan stands too close to a corpse, a warning message will appear to warn the player. If Yandere-chan is holding a corpse, NPCs will immediately deduce that she is the murderer. If Yandere-chan is bloody, holding a bloody weapon and/or visibly insane, and standing near a corpse, the same conclusion will be met. Students will act upon their persona as if witnessing a murder, while teachers will chase Yandere-chan down, resulting in the Apprehended Game Over. If Senpai sees her. she'll automatically get the Heartbroken Game Over.
Holding a Weapon
If Yandere-chan is holding a suspicious weapon, a warning message will appear to warn the player to put it away when near NPCs. This is accomplished by pressing the 1 key. Note that the katana, the circular saw, the baseball bat, and the shovel cannot be hidden; and will be dropped instead of being put away. If Senpai or a teacher see Yandere-chan with a notably dangerous weapon, Yandere-chan will get a Game Over. If a student sees her, her reputation will lower.
Yandere-chan will only become visibly bloody if she has attacked an NPC with a weapon and killed them, or dismembered a corpse, which leaves blood on both her uniform and her body. NPC reactions are the same as when they see Yandere-chan holding a weapon, although they are accompanied with different dialogue. To get rid of the blood, she must enter the Girls' Shower Room, take off her clothes by the lockers, and then bathe in the bath room. The bloody uniform that is left must be disposed of to maintain School Atmosphere and to leave no evidence, although in the future bloody uniforms may be used to frame another girl.
As Yandere-chan commits murder, her sanity will drop. If it is low enough to turn the HUD's cardiograph heartbeat red, then the player will receive a warning that Yandere-chan is visibly insane. When Yandere-chan has low sanity, a shadow will cover half her face, her eyes will become dull and her body will begin to twitch. To restore sanity, she can either laugh insanely, stand near Senpai, or "use" a photo of him. If caught visibly insane by NPCs, the consequences will be the same as when Yandere-chan is caught holding a weapon with different dialogue.
When Yandere-chan positions her camera to focus on a female student's chest, rear or panties, the Visibly Lewd warning message will appear. The consequences are the same as when Yandere-chan is caught holding a suspicious weapon, with different dialogue. Taking lewd photos of female NPC's without a proper AI (such as the Rival-chan) will not activate this warning message, due to the incomplete AI.
During class time, Yandere-chan is expected to be in her own classroom. If she decides to enter a different classroom during one of the class periods, the class teacher will eventually notice her. This activates the Intruding warning message immediately upon entrance. The teacher will give four warnings before losing their patience and expelling Yandere-chan. Only a teacher will react to an intrusion in her classroom.
This warning message also appears if Yandere-chan is caught eavesdropping on a private conversation, such as Saki Miyu's and Kokona Haruka's conversation during Monday's lunchtime. If she walks in on the conversation enough that the NPCs can see her, they will remind her that the conversation is private. They will then walk away without continuing any dialogue.
Late for Class
This warning message will appear the moment Yandere-chan is late for class. Depending on how late Yandere-chan is, the number of study points she would be allocated will decrease. So far, only teachers will scold her for being late. Other NPCs will not take notice.
Learned New Info
This notification message will only appear once the player character has learned certain information about someone, such as Kokona's compensated dating. Yandere-chan can use information gained against NPCs in certain ways.
Learned New Topic
- Main Article: Conversational Topics
This message will appear if Yandere-chan passes by or interacts with certain locations, objects, and NPC's. Learning new conversational topics allows Yandere-chan to discuss them with students, which is essential when matchmaking a rival with her suitor. A student's interests can be found when Yandere-chan takes a picture of a student, sends it to Info-chan, and presses the R key.
- Main Article: Sanity
The Sanity Meter is a cardiograph shown on the bottom right of the HUD and is used to show Yandere-chan's sanity. Certain Yandere actions slowly increase the intensity of the cardiograph from slowly pulsing bright pink to quickly pulsing red.
To restore Yandere-chan's sanity, she can laugh insanely for a period of time, stand near Senpai, "use" a picture of Senpai, or pass time for one hour.
- Main Article: Reputation
The Reputation Meter can be found in the bottom left of the HUD and is a general description of how others view Yandere-chan. A small arrow indicating to the left indicates a negative reputation, while an arrow to the right indicates a positive reputation, and an arrow in the middle indicates neutral reputation.
Raising reputation will not currently affect interaction with students (such as asking for Student Favors). The pink heart icon shows where the Yandere-chan's reputation will be after a gossiping period.
Raising Yandere-chan's reputation can be accomplished by complimenting students and apologizing to students. When students catch Yandere-chan performing suspicious actions, such as carrying a weapon or taking panty shots, her reputation drops.
In the future, reputation will be an extremely important issue: if Yandere-chan's reputation drops to -100, Senpai will reject her love confession, leading to a Game Over.
The player can interact with NPCs or objects in many ways, like picking up an item or talking with someone. When there's a chance to perform an action, a button prompt will appear showing the button that must be held down. The name of the item will also show up depending on what it is. When Yandere-chan is not close enough, a square will appear instead.
If an action produces noise, a red speaker icon will appear on top of the button prompt. When the action begins, a progress bar will appear on screen, indicating to the player when it will end. NPCs will react to noises. Noises can be covered up with the radio.
If a real-life band uses their tracks in the game, a small “Now Playing” box will appear in the bottom-right corner of the screen when their track starts playing. It will disappear after several seconds.
When Yandere-chan is in the Gaming Club she can play several games to boost her stats. After every game, a pink "POWER UP" sign will appear accompanied by a jingle. It will disappear after three seconds.
The Frame Rate section of the HUD indicates how smoothly Yandere Simulator is running as measured in frames per second. A low frame rate means the game is running slowly, while a high frame rate means the game is working fast and comfortably. It was located in the upper half of the left side of the HUD before the February 15th, 2016 Build where it was moved to the right. In the March 31st, 2016 Build, it has a black border around it.
The Time section of the HUD indicates the in-game time and is displayed on the top right.
At the top, the clock time (including whether it is AM or PM) is shown.
Right below the clock time, in smaller letters, the current stage of the school day is stated. These stages are Before School, Lunchtime, Classtime, and After School. While in the Aishi House, it will instead display the current location as At Home.
The bottom text indicates the current day of the week.
The delinquent timer by the disposal area in Akademi High School indicates when the delinquents will spawn or despawn. It will count down to zero, before resetting again.
If this indicator appears, then Yandere-chan is breaking rules and students will become suspicious if they are around her. This pairs with the warning messages at the top of the screen. The same indicator appears when Yandere-chan has positioned a dumpster in the perfect spot to catch a falling corpse, but moving a dumpster doesn't seem to break any known rules.
- Main Article: Police
The Police Timer section of the HUD is displayed in the top left corner of the screen when the police have been called to the school. The player is shown a timer that counts down from five minutes to when the police will arrive.
The HUD will show whether or not Yandere-chan has cleaned up the blood, disposed of her bloody clothing, disposed of her bloody weapon, disposed of any body parts, and disposed of any corpses. Yandere-chan will not get caught as long as she at least disposes of the uniform, gloves, and weapon. If not, the police will find Yandere-chan's DNA on each of these, leading to a Game Over.
- Main Article: Kidnapping
When entering the northeastern storage room on the first floor, a Kidnapping Checklist will appear onscreen, telling the player if they are currently meeting all of the criteria to perform a kidnapping or not. If the player doesn't meet all the criteria, Yandere-chan will kill the victim instead. The checklist indicates that the player is possessing a tranquilizer, their biology stats are at level 2, the follower is female, a syringe is currently being held in the hand, and that the door is closed.
- Main Article: Schemes
When completing a scheme, instructions for each step are located in the top right corner.
Frame For Dark Secret
Frame For Theft
Frame For Contraband
Frame For Panty Shots
Frame For Cheating
The Inventory HUD is displayed in the bottom of the screen when the buttons 1-4 are pressed, to show which items the player has in her inventory. There are only three inventory spaces, and a hidden fifth one for wearing the Cello Case. This may eventually be changed to a grid based inventory system, where the player has to make room to carry anything else, similar to Resident Evil. The inventory also may be stored in Yandere-chan's skirt.
- Main Article: Bedroom
When in Yandere-chan's Bedroom, a HUD will appear in top right hand corner, which tells the player the time, place and day. When the player walks up to the bed, the computer, the television, her panty drawer, Senpai Shrine, the corkboard or the door, a small HUD will appear saying the respective words.
- Main Article: Mission Mode
Mission Mode displays most of the usual HUD items but with a black and white colour scheme, rather than a pink and black scheme. The Reputation Meter is replaced with an Awareness Meter. It will increase when students see Yandere-chan acting suspiciously (e.g. holding a weapon). If the Awareness Meter reaches 100, Yandere-chan will fail the mission as she has blown her cover.
Yanvania: Senpai of the Night
- Main Article: Yanvania: Senpai of the Night
While playing this video game, there are two main HUD elements. On the left is Beldere-chan's health. It is colored red and depletes when taking damage. When she attacks zombies, she also gains experience, which is shown in the green bar on the bottom of the screen. When her EXP bar turns completely green, Beldere-chan reaches a new level. As the zombies never stop spawning, she can fill the experience bar as much as she desires until she reaches level 99.
Dracula-chan also has a health bar when Beldere-chan fights her, located on the right side of the screen. It flashes rainbow during the whole battle. It depletes when she is hurt and it turns clear when she is defeated.
- Main Article: Removed Content
Location indicators used to appear when Yandere-chan stood in front of a door, telling the player what room she was near. The name of the room she was about to enter was shown above the Sanity Meter and only appeared if Yandere-chan was right in front of or in the specified room.
They told the player which classroom, exit, or office the main character was currently at. This was removed in the November 15th, 2015 Build when name tags were added next to the rooms, except for the Greenhouse HUD, which was implemented after these were removed.
When in Buraza Town, a biking HUD would appear in the bottom right hand corner, which told the player how long they had spent in town (time taken to get to school) and Yandere-chan's longest wheelie.
- If Yandere-chan kills a student in a way that doesn't leave evidence (e.g. drowning), and a witness manages to activate the police timer and calls the police, the blood, uniform, body parts, and weapon warnings will still appear. However, they will already have ticks next to them.
