lerp_line_points(x1, y1, x2, y2, count, [include]) -> List of coords [x,y], count*2

Returns multiple points evenly distributed along a line, optionally including endpoints

Syntaxe

var list = lerp_line_points(x1=10, y1=10, x2=20, y2=20, amount=5, include=true)

Arguments

Name	Required	Default	Description
`x1`	yes	-	x-coordinate of the first point
`y1`	yes	-	y-coordinate of the first point
`x2`	yes	-	x-coordinate of the second point
`y2`	yes	-	y-coordinate of the second point
`count`	yes	-	Number of points to generate
`include`	-	-	True to include the two ends of the line (default: false)
