|
|||
purpose. Rating is 1, 2 or 3. A higher rating for such a group implies
|
||||
faster digging time.
|
||||
|
||||
Also, the **level** group is used.
|
||||
The **level** group is used to limit the toughness of nodes a tool can dig
|
||||
and to scale the digging times / damage to a greater extent.
|
||||
|
||||
^ PLEASE DO UNDERSTAND THIS, otherwise you cannot use the system to it's
|
||||
full potential.
|
||||
|
||||
Tools define their properties by a list of parameters for groups. They
|
||||
cannot dig other groups; thus it is important to use a standard bunch of
|
||||
groups to enable interaction with tools.
|
||||
|
||||
**Example definition of the digging capabilities of a tool:**
|
||||
**Tools define:**
|
||||
* Full punch interval
|
||||
* Maximum drop level
|
||||
* For an arbitrary list of groups:
|
||||
* Uses (until the tool breaks)
|
||||
* Maximum level (usually 0, 1, 2 or 3)
|
||||
* Digging times
|
||||
|
||||
**Full punch interval**:
|
||||
When used as a weapon, the tool will do full damage if this time is spent
|
||||
between punches. If eg. half the time is spent, the tool will do half
|
||||
damage.
|
||||
|
||||
**Maximum drop level**
|
||||
Suggests the maximum level of node, when dug with the tool, that will drop
|
||||
it's useful item. (eg. iron ore to drop a lump of iron).
|
||||
- This is not automated; it is the responsibility of the node definition
|
||||
to implement this
|
||||
|
||||
**Uses**
|
||||
Determines how many uses the tool has when it is used for digging a node,
|
||||
of this group, of the maximum level. For lower leveled nodes, the use count
|
||||
is multiplied by 3^leveldiff.
|
||||
- uses=10, leveldiff=0 -> actual_uses=10
|
||||
- uses=10, leveldiff=1 -> actual_uses=30
|
||||
- uses=10, leveldiff=2 -> actual_uses=90
|
||||
|
||||
**Maximum level**
|
||||
Tells what is the maximum level of a node of this group that the tool will
|
||||
be able to dig.
|
||||
|
||||
**Digging times**
|
||||
List of digging times for different ratings of the group, for nodes of the
|
||||
maximum level.
|
||||
* For example, as a lua table, ''times={2=2.00, 3=0.70}''. This would
|
||||
result the tool to be able to dig nodes that have a rating of 2 or 3
|
||||
for this group, and unable to dig the rating 1, which is the toughest.
|
||||
Unless there is a matching group that enables digging otherwise.
|
||||
* For entities, damage equals the amount of nodes dug in the time spent
|
||||
between hits, with a maximum time of ''full_punch_interval''.
|
||||
|
||||
Example definition of the capabilities of a tool
|
||||
-------------------------------------------------
|
||||
tool_capabilities = {
|
||||
full_punch_interval=1.5,
|
||||
max_drop_level=1,
|
||||
groupcaps={
|
||||
crumbly={maxwear=0.01, maxlevel=2, times={[1]=0.80, [2]=0.60, [3]=0.40}}
|
||||
crumbly={maxlevel=2, uses=20, times={[1]=1.60, [2]=1.20, [3]=0.80}}
|
||||
}
|
||||
}
|
||||
|
||||
**Tools define:**
|
||||
* Full punch interval Maximum drop level For an arbitrary list of groups:
|
||||
* Maximum level (usually 0, 1, 2 or 3) Maximum wear (0...1) Digging times
|
||||
This makes the tool be able to dig nodes that fullfill both of these:
|
||||
- Have the **crumbly** group
|
||||
- Have a **level** group less or equal to 2
|
||||
|
||||
**Full punch interval**: When used as a weapon, the tool will do full
|
||||
damage if this time is spent between punches. If eg. half the time is
|
||||
spent, the tool will do half damage.
|
||||
Table of resulting digging times:
|
||||
crumbly 0 1 2 3 4 <- level
|
||||
-> 0 - - - - -
|
||||
1 0.80 1.60 1.60 - -
|
||||
2 0.60 1.20 1.20 - -
|
||||
3 0.40 0.80 0.80 - -
|
||||
|
||||
**Maximum drop level** suggests the maximum level of node, when dug with
|
||||
the tool, that will drop it's useful item. (eg. iron ore to drop a lump of
|
||||
iron).
|
||||
level diff: 2 1 0 -1 -2
|
||||
|
||||
**Maximum level** tells what is the maximum level of a node of this group
|
||||
that the tool will be able to dig.
|
||||
Table of resulting tool uses:
|
||||
-> 0 - - - - -
|
||||
1 180 60 20 - -
|
||||
2 180 60 20 - -
|
||||
3 180 60 20 - -
|
||||
|
||||
**Maximum wear** determines how much the tool wears out when it is used for
|
||||
digging a node, of this group, of the maximum level. For lower leveled
|
||||
tools, the wear is divided by //4// to the exponent //level difference//.
|
||||
This means for a maximum wear of 0.1, a level difference 1 will result in
|
||||
wear=0.1/4=0.025, and a level difference of 2 will result in
|
||||
wear=0.1/(4*4)=0.00625.
|
||||
|
||||
**Digging times** is basically a list of digging times for different
|
||||
ratings of the group. It also determines the damage done to entities, based
|
||||
on their "armor groups".
|
||||
* For example, as a lua table, ''times={2=2.00, 3=0.70}''. This would
|
||||
* result the tool to be able to dig nodes that have a rating of 2 or 3
|
||||
* for this group, and unable to dig the rating 1, which is the toughest.
|
||||
* Unless there is a matching group that enables digging otherwise. For
|
||||
* entities, damage equals the amount of nodes dug in the time spent
|
||||
* between hits, with a maximum of ''full_punch_interval''.
|
||||
Notes:
|
||||
- At crumbly=0, the node is not diggable.
|
||||
- At crumbly=3, the level difference digging time divider kicks in and makes
|
||||
easy nodes to be quickly breakable.
|
||||
- At level > 2, the node is not diggable, because it's level > maxlevel
|
||||
|
||||
Entity damage mechanism
|
||||
------------------------
|
||||
Damage calculation:
|
||||
- Take the time spent after the last hit
|
||||
- Limit time to full_punch_interval
|
||||
- Take the damage groups, assume a node has them
|
||||
- Damage in HP is the amount of nodes destroyed in this time.
|
||||
|
||||
Client predicts damage based on damage groups. Because of this, it is able to
|
||||
give an immediate response when an entity is damaged or dies; the response is
|
||||
pre-defined somehow (eg. by defining a sprite animation) (not implemented;
|
||||
TODO).
|
||||
- Currently a smoke puff will appear when an entity dies.
|
||||
|
||||
The group **immortal** will completely disable normal damage.
