Can one NewGRF reference a base set?

[Lakie]

Since the code you've shown us looks correct, could the error in the graphics callback handler not being updated to point to the random action2 rather than the standard one?

[Dante123]

-1 * 0 02 04 A0 // Action2, ID A0
00 01 // 0 when loading, 1 when running (or vica verca)
\w0 // First set in the prev. Action1

-1 * 0 02 04 A1 // Action2, ID A1
00 01 // blabla
\w1
[/code]

Then for the var2, looks correct as far as i can see, but let me try

Code: Select all

-1 * 0  02 04 B0 80 // Action2, stations, ID, Random
              00 00 // See below **
                 02 // Number of randoms
              A0 00 // First  random obj
              A1 00 // Second random obj

Now, remember to refrence B0 in the Action, or the next var2/callback chain.


** According to the specs might the first set of 00's be: (or 00 if none of theese)

Code: Select all

Bit	Value	Trigger
0	01	new cargo waiting
1	02	no more cargo
2	04	train arrives (starts unloading/loading)
3	08	train leaves (done unloading & loading)
4	10	train loads or unloads cargo
5	20	train reserves platform (using PBS)

The second pair of 00's are might need to be 02 as well, but 00 should work fine as well as far as i've understood the wiki.


For NuTracks i use some random things as well, and your code looks pretty much like mine...

Code: Select all

*Action1 with 4 sets
-1 * 0  02 10 41 00 01 \w0
-1 * 0  02 10 42 00 01 \w1
-1 * 0  02 10 43 00 01 \w2
-1 * 0  02 10 44 00 01 \w3
-1 * 0  02 10 4C 80 00 00 04
                       41 00
                       42 00
                       43 00
                       44 00

grrrrr still not working :/

using this code

Code: Select all

sprite 4 till 11 are for the random build/placement factor.
it only places the sprite as it should, but not the one from the second set.

my thought is that it somehow clashes with the other action 2 sprites behind it ?

attached the test nfo/pcx/grf

Changes between //** and **.

Randomizer was not being referenced anywhere. Make sure you can work through the code and find a chain for each of the outcomes you want.
And a small change to the sprite offsets.

W00t w00t!
working

now i will try to understand how and can get back to the drawing board to get those kick-ass sprites drawn

[Dante123]

just 1 more quick thought, and i think it should not have big changes, but i cant find how...

how do i make the sprite change depending on cargo ? (with that same code from zero.eight 2 posts above this one)

[zero.eight]

Two ways to do that. First one is by specifying cargo IDs in the station's Action 3 and linking them to Action 2s. That doesn't look particularly fun so I haven't tried it yet but I will at some point.

Another way is with a VarAction 2 using var60. Var60 takes a cargo type number as its parameter and returns the amount of cargo waiting for that cargo type. You can then create ranges to choose a graphics set if the value is within a particular range. I haven't tested the code and it won't work straight away. You will need to choose Action 2s to use for each of the ranges and put the sprite itself (I numbered it 16) into the graphics chain. You will probably want to put it before the Random Action 2 (15) and change all the references to 15 to 16. You might need to add more graphics as well

Another nice possibility is to make the action2s returning results for CB14 directly. In this way, you´ll get the increments of cargo amount automatically (via <numlittlesets> and <numlotssets>). This is the method NewStations uses for displaying passengers on platforms.
