</>What does Damage Multiplier do?
Damage Multiplier lets you tune how hard Happy Room weapons and traps hit the dummy. Choose any value from 0× through 100× in half-step increments, then enable the effect for your next laboratory test. The multiplier is applied once to each original hit, including attacks that spread damage across several body parts. Disable it to return immediately to ordinary weapon damage.
</>What is Damage Multiplier?
Damage Multiplier provides precise Happy Room damage control from harmless 0× tests through extreme 100× destruction. A recursion guard keeps body-part damage spreading from multiplying the same original attack repeatedly.
</>Common questions about Damage Multiplier
What does Damage Multiplier do in Happy Room?
Damage Multiplier for Happy Room scales damage dealt to the dummy by the value selected in ProjectMods. A setting of 2× doubles each original hit, 10× makes it ten times stronger, and 0× creates a no-damage physics test. The effect covers the central dummy damage route used by weapons and traps, making it useful for both controlled comparisons and extreme destruction without editing every placed item separately.
How does the multiplier handle damage spread across body parts?
Damage Multiplier for Happy Room applies the chosen value once to the original attack. Happy Room can spread part of a hit from one body section to several others, so multiplying every nested spread would inflate the result repeatedly. The mod tracks that one attack while it is being processed and leaves its secondary distribution alone. This keeps 2× behaving like a true double rather than unexpectedly becoming 4× or more.
Can Damage Multiplier make attacks harmless?
Damage Multiplier for Happy Room supports 0× damage for experiments focused on force, motion, timing, or room choreography rather than destruction. Weapons can still activate and apply their ordinary movement effects, while the numeric damage entering the dummy is reduced to zero. Individual devices may have special effects beyond direct damage, such as moving, freezing, burning, or removing objects, and those behaviours are not promised to disappear at 0×.
How high can I set the damage value?
Damage Multiplier for Happy Room offers values from 0× to 100× in 0.5 steps. Lower values are useful for careful comparisons, while large values make compact setups reach extreme totals quickly. Change the slider whenever you like; the current selection is used for later hits while the toggle is enabled. The mod clamps unexpected values back into the supported range so the laboratory does not receive an accidental negative or excessively large multiplier.
What happens when the multiplier is disabled?
Damage Multiplier for Happy Room returns new hits to their ordinary damage immediately after the toggle is disabled. It does not undo damage already dealt, revive the current dummy, reset a score, or change saved weapon upgrades. That makes the toggle suitable for mixed experiments: begin with normal damage, enable a stronger phase for part of the sequence, then switch back without rebuilding the room or replacing every weapon.
