Tutorial Part.1 – Web Game Beat Map

When creating a beat map for Ero Beat, we start by creating a “Web Beat Map”.

If we want a VR beat map, we add VR elements to the Web Beat map.

The reason we start from Web is because a Web Beat Map is easier to edit at first.

Part.1 describes how to create a Web Beat map.

Tutorial Part.2 – VR Beat Map

If anyone wants to contribute to the VR main page with beat maps

Talk to me about the music choice because I cannot accept copyrighted musics.

I pay 100$ for a completed VR beat map.

Required: DirectX9 Runtime

*Video package has separate subtitle files. Use them if the subtitles are blocking your view. All videos with subtitles are included in this package.

System Requirements
  1. 64bit Windows 8.1 or 10.
  2. An external GPU is recommended, anything better than the Intel GPU will do. For example, my 7 year old i3 Haswell laptop with Geforce 840M is good enough for this. If you have only Intel GPU, it won’t pleasant to edit (not impossible)
  3. Recommended screen resolution is 1920×1080, windows font size should be at 100%. (150% font size will mess the UI layout and make the program unusable)

*1366×768 resolution is still usable, won’t be easy to edit, though.

Antivirus Trouble – Add an exception

With a certainty, the gametool64.exe program will be blocked by an antivirus program. The symptom varies, it won’t run, or it may not load the saved map files properly.

Example of my Avast Free version – added gametool64.exe to the exception like this.

Tutorial Part.3 – Finding the correct BPM

Usually, entering a slightly lower BPM and increasing as it go will be easier. Lower BPM is more visible to the human eye.

*note: This method cannot deal with initial blanks in songs. It requires the use of Audacity (next)

The definite method to find BPM – Audacity Rhythm Track

Match the music to the clicking sounds.

With this method, you can easily remove initial blanks, and find the exact beat both by your eyes and ears.

If anyone needs to learn more about this, I’ll make a short video later. (request in the comment)

Beat Editing Tips

1. BPM Detector site

Nothing is perfect in BPM detecting. Always be prepared for an error. Use the method in BPM tutorial to get the final BPM value.

2. Audio Format : MP3

Only MP3 for audio input. (no OGG)

Recommended bitrate : under 160kbps. Consider the web download size, use the minimum bitrate.

3. Notable Hot Keys in Beat Editor
  1. CTRL KEY : multi selection, or selection toggle
  2. ALT KEY : deselect mode
  3. DEL KEY : delete selected events
  4. LEFT/RIGHT KEY : move play position
  5. ESC Key : switch between “Select” and “Add Event” mode. Or stop music.
4. Breast Expansion Event

Breast Expansion event is in the “Other” category.

If this is properly mixed with grabbing and slapping events, it can be more fun. (use your imaginations) Like the breasts expand by grabbing, then shrink by slaps.

*One more : use the interpolation options for quick breast resizing. It’ll look more springy and realistic.

5. Placing the letter effects – new easier method

This method is added after the main tutorial is made.

The rules of placing letter effects.
1) place the letter effect where the player can see it.
2) Put it near the target
3) don’t block the next target.

6. Creating a 360 turn easily

This method is also good for 180 turns. Like 180 plus, or -180 minus turn.

Auto mode rotates to the closer direction. It is not predictable whether it’ll turn left or right if it’s 180 angle.

7. Target Appear Beats

This is an important factor of the gameplay.

The Default is 1.0, which means the target circle will appear one beat before the target hits. Songs with high BPM over 150 may require 2.0 in this field. If the target disappears too quickly, gamer cannot follow.

If you set this to 2.0, the actions must be placed with at least one blank beat between every action.

Say, this value is set to 2.0, and there are two actions placed side-by-side (no blanks). In such cases, the user’s going to see two targets at once. And it’s going to confuse the hell out of the user.

* Recently I’ve used 1.25 on Sophitia beat map, and it was okay. You may experiment with various values.

8. Conditional Breast Expansion

You may also need to deal with the “asymmetrical breast” situation (player succeeds to grab one side, fail to grab the other)

It’s done like this image:

‘Match smaller’ event takes care of the asymmetrical boob.

See the effect in this short clip:


9. Don’t React option

Sometimes, you hit a body part in a quick succession. The reaction may look ridiculous because it’s cut off and restarted over and over. There’s an option to deal with this.

This video explains it all:

*special note
You cannot deal with such cases by assigning (no reaction) to 2-4th reactions. You have to assign reactions to all four actions. Because we cannot know which one of the actions the player is going to hit.
