How is Color different from Color32?

Color holds components from 0 to 1 and Color32 from 0 to 255. Putting 255 into Color gives white, whatever you meant.

Will the colour work in rich text?

Yes, the tool also gives a tag for UI text and SCP:SL.

Why does my raycast hit the wrong thing?

A common mistake is passing the layer number instead of a mask. Physics.Raycast expects a bitmask, that is 1 << number.

How do I exclude one layer?

Invert the mask with ~, for example ~(1 << 2) for everything except the Ignore Raycast layer.

Why does Unity show different angles than I typed?

The same rotation has several Euler forms. Unity stores a quaternion and picks one of them when reading.

In what order does Unity apply the axes?

Unity rotates around Z, then X, then Y. The tool calculates in the same order.

Why does normal gravity make the jump feel heavy?

Games rarely use -9.81 because the jump then takes too long. You set height and time and derive the gravity, as here.

Where do the formulas come from?

From uniformly accelerated motion: gravity is 2h over t squared, and the initial velocity is 2h over t.

Colour: how to use it in three steps

The tool as a schematic with this page's example. Each step's number stands where you take it: in the fields, at the result or outside the tool.

Unity colour

What you enter

#414df2, alpha 1

Pick a colour or type a hex code.
Set the alpha.

What you get

new Color(0.2549f, 0.302f, 0.949f, 1f)
new Color32(65, 77, 242, 255)

Copy the C# line with Color or Color32.

#414df2 in Unity code

The same colour in two Unity types, computed by the tool's function: Color keeps channels from 0 to 1, Color32 from 0 to 255.

You enter

Hex: #414df2
Alpha: 1

Channels from 0 to 255

Color32: new Color32(65, 77, 242, 255)

What the tool does

Each pair of hex digits is one channel: 41, 4d, f2. Alpha 1 is 255.

Channels from 0 to 1

Color: new Color(0.2549f, 0.302f, 0.949f, 1f)

What the tool does

Each channel divided by 255, rounded to four places, trailing zeros dropped.

C#

new Color(0.2549f, 0.302f, 0.949f, 1f)
new Color32(65, 77, 242, 255)
