DDA

DDA stands for Don't Do Anything. DDA maps are purely made for entertainment, rather than playability. In these maps, the movement of the ninja is controlled not by the player, but by the tileset and objects like bounceblocks, launchpads, doors, and thwumps. An often used technique is gold delay.

Example of a DDA

The construction of a DDA usually takes a lot of time. In return for the time spent on making them, good DDAs are highly popular, for example: Tattletale by nevermore, The Improbability Drive and Rocket- ed. by formica, and Thriller by Sendy have been in the top 10 maps on NUMA. Some DDAs exploit a well-known glitch, which makes the ninja invulnerable. DDAs using this glitch must be played in debug mode to work properly, not in Userlevels. Some variants of DDAs are called hold right DDAs or hold left DDAs, and as the name suggests, instead of doing nothing, you have to just continously hold on to the right or left buttons to make it work. Some really special DDAs are "three-way", which means it can function as DDA, hold-left DDA, or hold-right DDA. Obviously, this takes a LOT of effort to create. Incredibly, Maximo's Michelle Five'fer and Clifty's On route 666 work in five and six directions, respectively.

The true challenge of a DDA is to make the ninja just miss the various traps and enemies, so creating a hair-raising spectacle.

Corpse DDA

A Corpse DDA, also known as a Death DDA or a DDABYD (Because You're Dead), is a DDA where the ninja dies at the very beginning, and goes through the whole map as a lifeless corpse. A variety of objects are used to propel the ninja throughout the map. However, these maps are fairly uncommon on NUMA, due to the lack of popularity.

Example

• Suicide booth 3001 by deathcloud33

KRADDA

KRADDA stands for "Keep-the-rocket-alive DDA". They are somewhat more difficult to make than normal DDAs since the designer must not only devise a way to keep the ninja alive, but also to keep the rocket alive throughout the course of the map. Creating one of these requires a lot of patience, because the rocket can move around in unexpected places, possibly ruining what you had in mind.

Examples

• Rocket- ed by formica
• Tattletale by nevermore

CTRDDA

CTRDDA stands for "Chase The Rocket DDA". These maps are insanely difficult to create, as the ninja must be following the rocket, not the other way around.

Examples

• romaniac's The Chaser's War series: II, III, and IV.

Note: The first Chaser's War was created by Clifty and is not a CTRDDA.

FLCDDA

A sub-domain of a corpse dda, Flying Limb Corpse DDAs are very rare as only 4 have been made. Your ninja dies in the beginning and one of his limbs will be propelled through the map, sometimes ending at the exit.

Examples:

• Exploding Universe by atomizer
• Shish Kabomb by script
