This small function allows you to quickly align a character to another character.
| Additional Info |
|---|
| Alignment is based on character center which is usually set near the feet. |
| There is no simple method for obtaining the top (y) pixel coordinate of the currently active character animation. |
Instructions
1. Add the main script to the Visionaire Studio Script Editor & set the script as a definition script.
2a. To align current character to another character...
alignChar(nil, "Tom")
2b. To align a specific character to another character...
alignChar("Tom", "Barry")
2c. To align a specific character to current character...
alignChar("Tom")
Main Script
function alignChar(c, t)
if c == nil then c = game.CurrentCharacter else c = Characters[c] end -- store character or current character
if t == nil then t = game.CurrentCharacter else t = Characters[t] end -- store character or current character
-- + --
local p1 = c.Position -- store characters position
local p2 = t.Position -- store target characters position
-- + --
local ax, ay
ax = p2.x - p1.x -- calculate x destination coordinate
ay = p1.y - p2.y -- calculate y destination coordinate
-- + --
local angle = math.deg( math.atan(ay, ax) ) -- calculate angle
if angle < 0 then angle = 360 + angle end -- some fallback? I don't remember why I wrote it
-- + --
c.Direction = angle -- update specified characters direction
end
Syntax Breakdown
| Name | Type | Description |
|---|---|---|
| c | "string" or nil | This should be a "string" value containing the name of the character you want to affect, or nil if you want to link to the current character. |
| t | "string" or nil | This should be a "string" value containing the name of the character you want to align to, or nil if you want to link to the current character. |
