Debugging

The following functions are available for debugging

Text

Prints will appear in the lua console and the most recent one in the bottom left corner of the screen.

Print 'hello world' into the lua console
print("hello world")

Any value can be printed, including tables

local table = {"hello", "world", self.object}
print(table)

You can print as many values as you want

print(self.object.name, "children:", self.object.children)

All debug draws can be cleaned up with Tab

Draw a cross at the origin
deb:cross(Vec3(0))

You can add a text label to the cross

deb:cross(Vec3(1,2,3), "hello")

You can change the color of the cross

local col = Vec3(1,0,1) --pink
deb:cross(Vec3(1,2,3), "hello", col)

Use deb:clear() to remove all drawings. That way you can also draw only for one frame

deb:clear()
deb:cross(self.transform.pos)

Line from start pos to end pos

local startPos = Vec3(1,2,3)
local endPos = Vec3(4,5,6)
deb:line(startPos, endPos)

Ray from start

local start = Vec3(1,2,3)
local ray = Vec3.forward * 10
deb:ray(start, ray)

You can draw any shape

Draw a 1m box at the origin
local sh = Box(Vec3(0), Vec3(1))
deb:draw(sh)
