I've been told that a long string is not as efficient because DG doesn't store strings very well.

Not to mention, without a replace character command, looping through a 100 character string isn't very efficient. Neither are doing operations on the string since then the string would be a 100 digit number...

Well, my idea is, suppose you had 10 flags on you, africanexploredtens0, africanexploredtens1, ..., africanexploredtens9.

africanexploredtens4 is currently set at 0011011001

The idea is, once you step into a room (eg, room vnum 12345), we have set tens %num.charat(4)%, and I'm hoping to link this to the flag africanexploredtens4, so we check whether the 5th position is a 0 or 1.

Hence I have set tensvar africanexploredtens%tens%.

What I'm hoping is that %actor.tensvar% (or some sort of variant) will give me the flag 0011011001, so I can check whether the respective position is 0 or 1.

I think Now says he'll put the command in soon.

I also have another question.

Suppose the player has a flag called africanexploredtens4

You would normally call this by %actor.africanexploredtens4%.

However, suppose the player is in room 12345. Using the code

Code:

set num %actor.room.vnum%
eval tens %num.charat(4)%
set tensvar africanexploredtens%tens%

we will have tensvar to be africanexploredtens4.

However, how would I then modify this flag? The following syntaxes:

Code:

%actor.tensvar%
%actor.%tensvar%%
%actor.%tensvar%
%%actor.tensvar%%

doesn't work for me, because the system interprets it as a flag called tensvar, instead of africanexploredtens4.

Anyone have any ideas?

[This is the problem I have. How do we change the kth position of a flag? eg, suppose I have the flag value 123, and I want to change it to 143. Apart from adding 20 to it, how do I change the 2 to a 4?Furthermore, expressions like 10^2 isn't recognized - the output will be 10^2 instead of 100, so even a workaround by adding would be a pain.[/i]If the kth position is a 1, check if the flag is 111..1111.If it is 111....111, we give player a new flag - explored, and delete the messy 111...111 flag.I'll look through the above script later when I'm at the office.]

My script would be just putting the flag

0000..0000000

on the player.

When the relevant room, say k is entered, we'll check if the kth position is a 0 or a 1.

If it is a 0, we change it to a 1. Update counter by 1.

If the kth position is a 1, check if the flag is 111..1111.

I can bring this down to 2-3 flags in worst case scenario, as opposed to 50 flags - I have the outline of the script (hint - it uses the charat function), so I'll do it in the weekend. Here's a short exercise for all of you.

Q1: What is the maximum string length a flag can hold? [5 marks]
Q2: Suppose a zone has seven rooms. Using the string 1100011, we can say that the first 2 rooms have been explored, the next three rooms have not, and the last two have. With this idea, write code to improve the previous script for the worse case scenario of flags [20 marks]

Suppose you want to give a player a challenge to explore the entire zone, and tell the player how many rooms he or she has yet to find. This is not easy to script, because a zone with 100 rooms might necessitate 100 (different) flags on the player.

It is possible to make a script (using the following outline shown) to reduce the worst case scenario of the number of flags to {Number of rooms /2} by considering the vnums in binary. However, it might be possible to reduce this number further - unfortunately I don't know what (other) commands I can use in scripting.

Therefore, here is a test case by considering vnums in base 10. While this is inefficient (it's not in base 2), the outline of the code is relatively easier to follow.

I would also like to know whether it's possible to create for loops in scripts - then the following code can be further compacted.

I have resorted to a hack - putting this as a room enter trigger, so this necessitates that *every* room have this trigger. Ideally, I'd like to have this trigger on an object in the player's inventory - so that if the player moves, then the object will trigger, and tally the number of rooms.

If anyone has any suggestions for improvements, or any shortcuts which I have overlooked, do post here, so everyone can benefit

Code:

*Code works like this:
*Every 10vnums are grouped together, from 00-09, 10-19, 20-29, .., 90-99
*Flags are labelled africanexplored0, africanexplored1, .. africanexplored99
*But if you have a group of 10, say africanexplored0, .. africanexplored9
*then you'll get the flag africanexploredtens0 (the tens0 denotes the tens
*position as 0). So here, the worst case scenario is the player gets 9 of each
*group, and has 90 extra flags. The 91st flag would mean the player completes
*one group of 10, and hence reduce the number of flags from 90 to 81.
*Of course, we can group 2 vnums together, to reduce the worst case scenarion
*to 50. I think this can be even reduced further, but I'm not sure what
*commands I'm able to use.

*For the code below, you can see I've only been using "if" statements, as
*I'm not sure if for loops, etc exists.

if !%actor.varexists(africanexploredall)%

Now, it just suffices to put a counter whenever the player enters a new room to increase the rooms explored by 1! Tada!

Hi all,

I'm not very sure about the different types of Object scripts, so here's an example of what I would like to happen.

I'm looking for a trigger to put on an object carried by a player. When the player enters the room, the object will check the vnum of the room. If the vnum is a certain number, then something happens.

I'm guessing this is ObjEnter type of trigger, but I'm not sure what the syntax is.

Help given would be appreciated. Thanks!

I think it would be good to consider exactly why people want to level.

My reasons for levelling were: No emphasis on PK - and GM makes it easy to explore the gameworld. Need to bear in mind that 4D is more focused on Questing. In that case, keeping the skills for the last 8 remorts without any other changes would lead to certain combinations being chosen over the rest. I'd say Priest and Thief, only because of buffs, "pick", decent speed and damage.

I..kind of have a database too, but to be honest, would it really help that much? In some sense, most of the good EQ / Items / Subskills come from quests...

I can TeX up maps and make them look colourful, but that's to the extent of it..
