This script allows you to turn texts spoken by characters into speech bubbles. It has been developed for Visionaire Studio 5.x.
| Quick note: The "Argo Bubbles" script is based on the "Advanced Speechbubble Script" by Sebastian aka turbomodus. | |
Instructions
1. Add the main script to the Visionaire Studio Script Editor & set the script as a definition script.
2. Create the bubble graphics & add them into the gui subfolder of your projects root folder - if the gui folder doesn't already exist, create it.
The font used in the speech bubbles is the regular font defined in Visionaire for a specific character, so you may have to adjust that to match your bubble design. The bubble itself is made of up to five graphic files: one for the main bubble and optionally up to four different pointers (for different directions).
Since the dimensions (width, height) of a speech bubble depend on the length of the text and the number of lines, there are limitations to what the bubbles can look like. It is not possible with this script to have elliptical or fancy-shaped bubbles. They need to be more or less rectangular, but may have rounded or chamfered corners. That's because the script splits the main bubble graphic into 9 tiles which are individually scaled and then recombined to match the size of the text.
◻️ The four corners (1, 3, 7, 9) will keep their look and size
◻️ The horizontal borders (2, 8) will get stretched/shrinked to the required width
◻️ The vertical borders (4, 6) will get stretched/shrinked to the required height
◻️ The center tile (5) is strectched/shrinked horizontally and vertically to fill the bubble
You usually want to have a pointer attached to the bubble, pointing to the character who is currently speaking. Depending on the direction the character is facing, the script either uses the right-pointing or the left-pointing pointer graphics. So you should at least provide two graphic files.
You also have the option of positioning the speech bubble above the character (that's the default, where the pointer is attached to the bottom of the bubble) or below the character's head (with the pointer attached to the top of the bubble and pointing upwards). If you make use of both possibilities (through the custom bubble style option of the script), you must provide four different pointers.
However, you don't have to use pointers at all. Just set all pointer path options to an empty string " " to get a bubble without pointer.
3. The script offers several options to adjust the speech bubbles to your needs. The options are commented with explanations inside the script.
One main feature is the ability to define as many bubble styles as you like. You could have a different bubble color for each character, for example. Or depending on where a NPC stands, that character might need a different positioning of the bubble than the default one. You can even define multiple styles for the same character. It is then possible to choose the appropriate style by setting a Visionaire value. Please read the comments inside the script on how to achieve this.
The last options are related to the events which the bubble creation is bound to: "textStarted" and "textStopped". Remember that you can register each type of event handler only once in a Visionaire project. So if you have already registered an event handler for the "textStarted" and/or the "textStopped" event, you can't do it again in this bubble script. Instead you have to put all your functions that use the same event handler into one function and bind that one to the event. The Argo Bubble script offers a convenient way to do this without messing up the main code.

-- CUSTOM BUBBLE STYLES
--[[
Add custom bubble styles to the "custom_styles" table. You can override all properties of the default style. Undefined properties will fallback to default.
Each custom bubble style is defined for a specific character. Add the name of the character as an additional "char" property. If you want the character to use the default style by default and use the custom style only in certain situations (or have several custom styles for him), read the following paragraph.
You can define multiple bubble styles per character. Add a Visionaire value called "argo_bubble" to the character to set the desired bubble style in-game. Counting starts with 1. If you set this value to a number that doesn't correspond to a custom style (e.g. 0), the default style will be used. If you don't add this value at all, the first bubble style definition for this character will be used if present. If you have only one custom style defined for a character and want to use only that, you don't need to add the Visionaire value.
Example:
local custom_styles = {
{
char = "Hero",
align_h = "left",
align_v = "bottom",
bubble_offset_x = -40,
bubble_offset_y = 80,
file_pointer_top_right = "vispath:gui/bubble_pointer_tr.png",
pointer_top_offset_y = 10
},
{
... next style definition here
