User:DrakRoar/SSB4 and SSBU parameters

A gigantic collection of technical parameters for Smash 4 () and Ultimate (), which I gathered from the work of various dataminers and organized in a more detailed format for documentation. This isn't intended to be added to the wiki as-is, but moreso as research of my own. Parameter names with a specific game icon (e.g. ) indicate it is only present in that game.

General parameters (battle_object)

Internal name/address	Meaning	Value	Notes
stick_clamp_max	Maximum stick value	120 118	Stick values range from [-128, -128] (bottom left) to [127, 127] (top right); 120 is the highest registered by the game for all four directions
stick_neutral	Stick deadzone range	0.2	Relative to maximum (effectively between -24 and 23)
clatter_button_dec_frame_mul	Mashing reduction multiplier for buttons	1.8	Used for all buttons, so the base mashing reduction value is only used for stick inputs (for example, if a status' duration is reduced by 8 frames with a stick input, a button input reduces it by 14.4 frames)
0x21af4b1219	Mashing cooldown for equal button inputs	1 frame	Buttons tied to the same action (e.g. X and Y for jump) count as the same input During cooldown frames, no mash inputs can be registered nor buffered, and frames passed don't reduce the status' duration The different button input cooldown is also used for button to stick inputs, and vice versa Overall, button inputs have a stronger effect on mashing than stick inputs but cannot be registered as fast
clatter_double_invalid_frame	Mashing cooldown for different button inputs	2 frames

damage_angle_ground_zero_speed_mul	Launch speed multiplier for grounded knockback	0.8	Factored on top of the base 0.03 multiplier
damage_down_on_ground_y_speed_mul	Vertical launch speed multiplier for grounded meteor smash	0.8	Tumble knockback only (bounce off) Applied after initial launch speed

fly_top_angle_hi		110°
damage_angle_ground_reaction_min	Sakurai angle knockback thresholds	60	If KB < 60, angle = 0° If KB >= 88, angle = 38° / 40° If 60 <= KB < 88: angle = (1 + 38 * (KB - 60) / (88 - 60))°; 38° maximum angle = (1 + 40 * (KB - 60) / (88 - 60))°; 40° maximum Maximum angle is 37°

damage_pull_attack_speed_max	Autolink angle launch speed cap	3	After the first 5 knockback frames from an autolink attack, its launch speed is capped to this value, and in the case of the 366° / 367° angle, it changes to fully match the attacker's momentum at the time of the hit
damage_pull_speed_intp_frame	Period before autolink angle cap	5 frames
damage_turn_speed_ground_mul	Grounded launch speed for reverse effect attacks	1 2.25	Coded as a multiplier to the resulting launch speed from knockback calculation (all reversing attacks use 80 FKB and 100 KBS) Due to a glitch, this launch speed does not apply if the opponent was hit by a flinching move beforehand, which can only be fixed irregularly by floor or ledge getups, and lasts for the rest of the stock otherwise Coded as launch speed applied to the character (all reversing attacks use 0 KB) The grounded value applies at the attack's launch angle, but only the horizontal component is kept
damage_turn_speed_air_mul	Aerial launch speed for reverse effect attacks	0.9 2
down_damage_reaction	Minimum knockback for weak lock	7	Lasts 12 frames; knockback below this amount simply causes the knocked down target to stand up

slip_damage_reaction	Minimum knockback for base trip chance	55	Tripping lasts 39 frames; requires this (or hitbox-specific bonus trip chance) and the knockback to not lift the target off the ground Skips victim's hitlag if the tripping attack is electric (for some reason)
capture_cut_damage	Accumulated external damage to escape a grab	10%	Applies to the grabbed character; attacking the grabber ends the grab regardless of damage or knockback There's another value for minimum external damage per hit to escape a grab, equal to 11% (capture_cut_attack_power), but is obsolette due to being higher than this value
damage_fly_quake_m	Minimum hitstun for camera shake (two intensities)	50
damage_fly_quake_l		70
damage_fly_speed_up_reaction_frame_min	Hitstun range for balloon knockback	30	Initial speed multiplier: 1 + 5 * (hitstun - 30) / 50; 1 minimum Subsequent frames: (initial FAF * 0.3 - new FAF) / (initial FAF * -0.7)

damage_fly_speed_up_end_rate	Balloon knockback factor	70
damage_fly_speed_up_max_mag	Balloon knockback maximum speed multiplier	6
