Training Mode (トレーニング, Training), or simply Training in Brawl, is a mode available in all games of the Super Smash Bros. series where the player can manipulate overall gameplay of a match and experiment with the CPU without the restrictions of standard Versus Mode. The mode's features, behaviors, and properties vary throughout the series.
As implied by its name, Training Mode is intended to allow players to practice using characters in a non-serious setting. All matches within the mode are actually Time matches of infinite length, as seen on the Jumbotrons featured in the Pokémon Stadium stages. The player can use any character they wish and select one CPU character as their opponent. Any stages available to the player can be used in the mode, including Smash 4's Ω form stages and Ultimate's Battlefield form stages, except for the custom stages in Ultimate for unknown reasons.
In Ultimate, Training Mode features an exclusive stage (although other stages can still be selected) with a grid that displays exact distances between points. A new modifier allows drawing of launch distances and trajectories for an attack: a red, green and blue line will display the predicted distance and trajectory for that attack as if it was used against an opponent at 0%, 50% and 100% damage, respectively. The weight of the targeted fighter is factored into the predictions as well, allowing for detailed calculation of how well an attack will perform in any given circumstance.
Interestingly, Stale-Move Negation is not present in the mode for Brawl or SSB4, and rage is not present in SSB4. A new modifier in Ultimate allows the player to turn these elements on or off. Additionally, pausing in SSB4 and Ultimate will freeze the stage and relevant hazards, but not characters or items; in Ultimate, attacks will also not connect while the game is paused, effectively making all characters intangible.
Within Training mode, a specialized UI overlay, unavailable in any other mode, is displayed on the screen in order to show data relevant to gameplay. The overlay is always present in Smash 64 and Melee, disabled by default in Brawl, and enabled by default in Smash 4 and Ultimate.
The overlay contains information regarding:
In addition to allowing players to train against an ordinarily idle opponent or to perfect their timing in combos or other advanced techniques, the player has the option of manipulating the environment of the stage or gameplay. Initially limited in Smash 64, modifiers within later games were more advanced.
Modifying the match's parameters requires using a specialized menu accessed by pressing the pause button; while this menu stops the CPU from performing actions, it does not actually pause the battle, and so items on the stage and other stage hazards can potentially harm the player while they apply modifiers. As the Nintendo 3DS has two screens, the bottom touch screen can be used to manipulate the environment without having to pause the game.
Ultimate added several new options:
Ultimate also allows Figure Players to be used in Training Mode in place of either the player or CPU. However, FPs will not gain any experience, and in the latter case the "No. of CPUs," "CPU Behavior" and "CPU Shuffling" options are disabled.
Character Loading Input Delay
In Brawl, after adding additional CPUs to a match, those CPUs do not function correctly when set to Control. It is unclear exactly what causes it, but they do not act on the same frame as another character using the same input, causing both input delays and ignored inputs. Opening and closing the training menu (by pressing the pause button) fixes this until a new CPU is added. This does not occur in Melee.
Combo Counter inaccuracy
There appears to be an issue with the combo count in Smash 4 which is demonstrated in a video by the Beefy Smash Doods, where true combos will not be displayed as combos and vice versa. This is believed to be due to the formula for hitstun being different in training mode than in a regular smash, although it may also involve not being correctly adjusted for hitstun cancelling or gravity compensation.
