Prim Mode ​

Prim Mode is the default way to build a HUD: you link prims, name them, and each prim becomes a button. It is what the Quickstart uses.

How it works ​

1. Build the HUD out of prims in Second Life: one prim per button, linked to a root prim.
2. Name each button prim.
3. Re-scan in the panel; the prims appear in the left column.
4. Click a prim's name to create its function and add actions.

Everything in Buttons and Functions applies.

When to choose Prim Mode ​

• Your HUD design is made of separate mesh or prim buttons anyway.
• You want physical buttons with different shapes, hover glow or per-button textures.
• The HUD has a handful of buttons.
• You also need events; events are managed in Prim Mode.

When to consider UI Mode instead ​

• Your HUD is a single textured panel with dozens or hundreds of clickable areas.
• You do not want to link and name prims one by one.
• You want to move buttons around by dragging, with alignment guides.

See UI Mode. Both modes can be used in the same project: physical prim buttons plus drawn areas on the root prim's texture.

Switching modes ​

Click PRIM or UI below the memory bar. Switching does not delete anything; each mode shows its own kind of buttons.
