Bhop

What is Bhop? #

Bhop, short for “Bunny Hop”, is a very popular gamemode found in many games, such as CS:GO, TF2, and others.

The core mechanic, “bhopping”, is when the player jumps repeatedly, the moment they hit the ground, allowing them to maintain their current velocity. In order to maximize the likelihood of inputting the jump exactly when you hit the ground, players used to bind jump to the scroll wheel, and then roll their mouse wheel very fast whenever they were about to hit the ground. This is sometimes known as traditional style bhopping. This method has fallen out of favor though, as unless the player can frame-perfectly input every jump command the best the player can hope for is a 50% chance of not losing speed. It’s more common now to rely on autobhop, an addon or mod which inputs a jump on the exact frame the player hits the ground every time. This functionality is built into MomentumMod

Porting Goldsrc maps to Source

This guide is a work in progress. If you have questions or problems ask for help in the Momentum Mod Discord. #

Before you start, you should know that maps with simple geometry work best for porting. Complex geometry can cause invalid solids which will need to be manually remade, and some textures will need to be realigned.

Prerequisites:

• Have a basic understanding of Goldsrc, Valve Hammer Editor, and potentially Trenchbroom

Download the .BSP and (in some cases) the .WAD #

Most Team Fortress Classic skill maps can be found on the TFC Refugees forum here: https://www.tfcrefugees.com/resources/categories/conc.4/
Maps downloaded from this forum always include any relevant custom content not packed into the map itself. Additionally many maps have descriptions and author info text documents included.
Of the files downloaded, the BSP is the actual map file, and the WAD contains the textures used in the map. In most cases custom textures will be embedded into the BSP itself.

toggle_jump

Toggles jump input for gamemodes with autohop.

Toggle resets when hitting a fail teleport (see trigger_teleport , trigger_momentum_teleport_progress , trigger_momentum_multihop , and trigger_momentum_onehop ), and when restarting a map or stage via mom_restart or mom_restart_stage respectively.

trigger_momentum_limitmovement

Trigger that prevents the player from doing specific keypress movements.

Keyvalue #

Track Number (track_number<integer>)

The track that this trigger belongs to:

• -1: All Tracks
• 0: Main Map
• 1+: Bonus Tracks

Flags #

Prevent the player from moving forward (8192)

(Disabled by default)

Prevent the player from moving to the left (16384)

(Disabled by default)

Prevent the player from moving to the right (32768)

...

trigger_momentum_multihop

Trigger that allows for multiple hops inside of it, and teleports the player if they stay inside for longer than the hold time.

Keyvalues #

Remote Destination (target<target_destination>)

The entity specifying the point to which the player should be teleported.

Local Destination Landmark (landmark<target_destination>)

When “Teleport mode” is “Landmark teleport”, teleported entities are offset from the target by their initial offset from the landmark (this entity).

Velocity Scale Factor (X Y Z) (velocityscale<vector>)
