* Value script *
Value wizard's terminology:
random			`r:0:4`	(min:max)
variable name		`v:value:"variableName"`
event direction		`e:direction:"eventName"`
event tileX			`e:tileX:"eventName"`
event tileY			`e:tileY:"eventName"`
event pixelX		`e:mapPixelX:"eventName"`
event pixelY		`e:mapPixelY:"eventName"`
event screenPixX		`e:screenPixelX:"eventName"`
event screenPixY		`e:screenPixelY:"eventName"`

(actual values can be entered directly:  42  "string"  )
(these can also be written manually in the outer interface)
(when the value script is parsed, the codes between the  `  are figured out and replaced with actual numbers... then the equation is evaluated.
(as a string / as math)
