Code editing

A quick guide to object editing.

In N's map data, each object is represented by a number, followed by "^" (hat), followed by a bunch of other numbers. You can create some levels which are impossible in Ned by manually editing the level data. This is mostly used for making custom jump pads and teleporters. The object data is seperated from the tile data by a "|" (vertical bar). The end of an object's data is marked by a "!" (exclamation mark). Tiles must come before objects in the map data.

Before we start, a couple bits of notation...

• For each object, the code is "code_number^argument1,argument2, etc". The first number indicates which object it is.
• Arguments listed as "x,y" will always refer to the position of the object, where x is horizontal and y is vertical. 24,24 is the top left corner. 24,576 is the bottom left. 768,24 is the top right. 768,576 is the bottom right. And 396,300 is the centre. A tile is 24 pixels to a side.

The ninja

5^x,y

Enemies

Guass Turret

3^x,y

Homing Turret

10^x,y

Mine

12^x,y

Floorguard

4^x,y,z

• Z was supposed to be the floorguard's facing direction, but editing it has no effect as Metanet Software decided not to implement a facing direction to the floorguards.

Thwump

8^x,y,direction

• Direction: 0 - right, 1 - down, 2 - left 3 - up. Any other value will make it stationary, the right side deadly, and the collision detection & graphics will be wrong.

Drone

6^x,y,path,seeking,type,direction

• Path: The pathfinding algorithm. 0 - surface follow cw, 1 - surface follow ccw, 2 - dumb cw, 3 - dumb ccw, 4 - alternate, 5 - random, anything else - immobile.
• Seeking: 0 - False, else - True (only effects zap drones).
• Type: 0 - zap, 1 - laser, 2 - chaingun, otherwise - harmless moving dot.
• Direction: 0 - R, 1 - D, 2 - L, 3 - U, same as for thumps.

Objects

Gold

• 0^x,y

Bounceblock

• 1^x,y

Launch pad

2^x,y,xthrust,ythrust

• Xthrust and Ythrust are how fast the ninja is pushed in the x and y direction. +xthust is right, +ythrust is down. 1 is the default strength for vertical/horizontal pads. For other orientations, you'll have to use trig (0.707106781186547 is the default for 45 degree angles). VERY sensitive. -1.5 ythrust will send you from the floor into the roof. Hard. ~1.35 is just roof height.

One way platform

7^x,y,direction

• Direction is the same as for thwumps and drones. 0 - R, 1 - D, 2 - L, 3 - U.

Exit

• 11^xdoor,ydoor,xswitch,yswitch

Door

9^x,y,alignment,trap,x2,y2,locked,A,B (The horror, the horror!)

• X,Y is for the switch if applicable.
• Alignment: 1 - bottom, otherwise - right.
• Trap: This door is a trapdoor. 0 - false, otherwise - true. Will be overrridden by locked.
• x2, y2: the position of door IN THE GRID (0,24 is bottom left).
• Locked: This is a locked door. 0 - False, 1 - True. If it conflicts with trap, it will default to a locked door.
• A and B have something to do with the door's alignment and position, but I'm unsure exactly how they work.

Tileset codes

• E = 1
• D = 0
• 1Q = 3
• 1W = 2
• 1A = 4
• 1S = 5
• 2Q = S
• 2W = F
• 2A = H
• 2S = I
• 3Q = ?
• 3W = >
• 3A = @
• 3S = A
• 4Q = 7
• 4W = 6
• 4A = 8
• 4S = 9
• 5Q = Q
• 5W = P
• 5A = N
• 5S = O
• 6Q = K
• 6W = J
• 6A = L
• 6S = M
• 7Q = C
• 7W = D
• 7A = B
• 7S = E
• 8Q = ;
• 8W = :
• 8A = <
• 8S = =

Note: Certain other characters(for example: Z or some special characters(hold alt press 2-3 numbers on numberpad for Windows, option(shift key for even more) and letter characters for Mac) ) will result in a unique tile that has very bizzare properties even though it may not look it.
