EnemySpawnRange

EnemySpawnRange

COMPATIBLE WITH COSMETICS UPDATE V0.4.0.

This mod is a host-only mod that changes the enemy spawn distance range from players.

By default, enemies try to spawn at valid level points between 5 and 15 units away from players instead of the vanilla 18 to 35 range.

It does not force enemies to spawn directly on top of players, inside players, or always in line of sight.

The game still uses valid internal level points and collision checks.

Features

• Change the minimum enemy spawn distance from players
• Change the maximum enemy spawn distance from players
• Apply one shared distance range to all enemies
• Use vanilla fallback when the custom range fails
• Respect the game's debug close-spawn behavior when enabled
• Skip custom spawn control in arena levels by default
• Skip custom spawn control in shop levels by default
• Run only after level generation is complete by default
• Host-only operation

How it works

The mod patches the shared enemy spawn function:

• SemiFunc.EnemySpawn

When an enemy is spawned, the mod reads the configured minimum and maximum distance, searches for a valid level point in that range, checks whether the point is blocked, and teleports the enemy there if the point is valid.

If no valid custom point is found, the mod can retry with the vanilla distance range of 18 to 35.

For REPO v0.4.0, the mod also avoids running before level generation has completed.

This prevents the mod from affecting menu, lobby, region selection, shop, or arena timing.

Important behavior

• This mod changes the allowed distance range for enemy spawn candidate points
• This mod does not guarantee line-of-sight spawns
• This mod does not guarantee face-to-face spawns
• This mod does not place enemies directly at player coordinates
• Very small ranges can reduce valid spawn points and may increase fallback usage
• If fallback is disabled and the range is too narrow, some enemy spawns may fail more often

• Maximum: true

ExcludeArena

If enabled, the mod does not override enemy spawn distance in arena levels.

• Default: true
• Minimum: false
• Maximum: true

ExcludeShop

Installation

• Install BepInEx 5 for REPO
• Place the mod DLL into the BepInEx plugins folder
• Start the game once to generate the config file
• Edit the config file if needed
• Host a game

Host-only behavior

Only the host needs to install this mod.

Clients do not need to install it for the enemy spawn distance changes to take effect.

Recommended values

• 0 to 8: very aggressive close spawning
• 5 to 15: close-range pressure
• 18 to 35: va
