Surf Tools for Hammer++ (Build 8870)

A mod of Hammer++ with surf-related features.

Features

Clip Angle Measurer

• When using the clipping tool, it will show the surf angle if it's surfable.
• Toggle: press o.

Ramp Angle Measurer

• When selecting a solid (not an entity or group), it will show the surf angle for each surfable face.

Curved Ramp Generator

• Generates a curved ramp from a start segment and inputting curve, direction, degrees, and number of segments.
• Usage: Select a start segment that’s not rotated, then press Alt + Shift + R.

Trigger Generator

• Creates triggers by extruding from selected faces.
• For now they are hardcoded to be 2 unit tall trigger_teleport.
• You can press Alt + Enter after to set the teleport destination in bulk.
• Usage: Select some faces with the texture tool, then press Alt + Shift + T.

Angle Fix

• Requires compiling with vbspplusplus.exe from the Tools++ compilers (for func_detail_illusionary)
• Usage: Select worldbrush rotated ramps and press Alt + Shift + A.

Face Extruder

• Allows you extend a brush by face. Useful for extending rotated ramps.
• Usage: Point at the end of a ramp in 3D view and press Alt + Shift + E. Move the mouse in either 3D or 2D views to extrude. Press the hotkey again to stop. Intrude/shrinking isn't currently supported.

About Angle Steepness Rating

When you see ratings like 5/10 with the angle measure tools:

• 5/10 → "Sweet spot" (~50 degrees)
• 0/10 → Just barely surfable
• 10/10 → Ranges from "probably too steep to be fun" all the way to "almost too steep to stay on the ramp"
• This may be tweaked in the future.

Notes

• There’s also a context menu in Tools → Surf Tools and in the right-click context menu.
• Support for Hammer++ builds beyond 8870 will be added when they're released.
