|
<h>Object Scripts</h>
|
|
<part>
|
|
<text>Object scripts control the complex behaviour of an object. For details on scripting see the <emlink href="script/index.html">C4Script</emlink> documentation.</text>
|
|
<h>Creation</h>
|
|
<text>For every object, the engine calls the function <a href="#Initialize">Initialize</a> in the object script when it is created and completed.</text>
|
|
<code>func Initialize()
|
|
{
|
|
<emlink href="script/fn/CreateContents.html">CreateContents</emlink>(Rock);
|
|
}
|
|
</code>
|
|
<text>An object with this script will be given a rock right after it has been created. The Initialize function is called only when the object has reached full size (a building only when its construction has been completed and a living being only when it is fully grown).</text>
|
|
<h>ActMap</h>
|
|
<text>An active object can also define activity script calls in its <emlink href="definition/actmap.html">ActMap</emlink>. The defined StartCall is made whenever an action begins (or repeats), an EndCall is made at the end of each activity. PhaseCall is called at each animation phase step and should only be used for very short animations. The call frequency of PhaseCalls is determined by the speed of the animation.</text>
|
|
<h>#include</h>
|
|
<text>An object script can also include the functionality of another script.</text>
|
|
<code>#include Clonk</code>
|
|
<text>At this position the complete script of the specified object definition (that of the clonk, in this case) is inserted, including all scripts that that script includes or got via <emlink href="script/AppendTo.html">#appendto</emlink>. The only exception is that every script is included only once, so including both the Clonk script and a script that is included by the Clonk script doesn't include that script twice. Other Obviously, the included definition must be valid and loaded. Declared functions can be overloaded by functions of the same name that occur later in the script. Also see <funclink>inherited</funclink>().</text>
|
|
<h>Interaction from other scripts</h>
|
|
<text>Other scripts can call functions of an object <code>obj</code> with the <code>-></code> and <code>->~</code> operators.</text>
|
|
<code>var obj = CreateObject(Flint); obj->Hit();</code>
|
|
<h id="ObjektCallsderEngine">Object calls made by the engine</h>
|
|
<text>
|

The engine calls the following functions is objects at the given time.

<h id="ScenSave">Scenario saving</h> <part>
|
|
<text>When the user chooses the "Save Scenario" option from the editor menu, the engine calls a global function SaveScenarioObjects defined in System.ocg/SaveScenario.c. This function writes all objects to the Objects.c file in their current state. The function stores all objects except the crew of currently joined human players and objects of a type that starts with GUI_. By default, objects are recreated using a call to <funclink>CreateObject</funclink> followed by setting a number of default properties like position, rotation, speed, action, if they are not in their default state.</text>
|
|
<text>For most object, the default saving method should be fine. However, it is possible to override the SaveScenarioObject callback to control how objects are created and which properties are set.</text>
|
|
<text>For example if a switch wants to save its target which is stored in a local variable called "target", the switch definition can override the callback:</text>
|
|
|
|
<code>local target;
|
|
|
|
func SetTarget(object new_target) { target = new_target; return true; }
|
|
|
|
func SaveScenarioObject(props)
|
|
{
|
|
if (!inherited(props, ...)) return false;
|
|
if (target) props->AddCall("Target", this, "SetTarget", target);
|
|
return true;
|
|
}</code>
|
|
<text>As a result, the generated Objects.c file will include the call to SetTarget if the switch is saved. Dependent objects should always either be passed to the AddCall function or stored as a string from the <funclink>MakeScenarioSaveName</funclink> function. If this is done, that object is marked as a dependency. The saving mechanism will ensure that any object this object depends on will be created before. In case of circular dependencies, the object property setting script is detached from object creation script.</text>
|
|
<text>If an object should not be saved in scenarios - for example, because it is just the helper of another object - the SaveScenarioObject callback should be overloaded to return false.</text>
|
|
<text>The object creation procedure can also be adjusted. For example, the waterfall object (defined in Objects.ocd/Environment.ocd/Waterfall.ocd) is created using the global functions CreateWaterfall and CreateLiquidDrain, which create a Waterfall object and attach an effect to it. To generate the creation functions from the effects, the waterfall overrides SaveScenarioObject:</text>
|
|
<code>func SaveScenarioObject(props)
|
|
{
|
|
if (!inherited(props, ...)) return false;
|
|
var fx_waterfall = GetEffect("IntWaterfall", this);
|
|
if (fx_waterfall)
|
|
{
|
|
props->RemoveCreation();
|
|
props->Add(SAVEOBJ_Creation, "CreateWaterfall(%d,%d,%d,%v)",fx_waterfall.X, fx_waterfall.Y, fx_waterfall.Strength, fx_waterfall.Material);
|
|
}
|
|
return true;
|
|
}</code>

<text>If you need access to one of the objects created in the editor, you can set its "StaticSaveVar" property to the name of a static variable. The InitializeObjects() function will then save the object in that variable.</text>

</text>
|
|
<text>By default, effects are not saved in scenarios. To force saving of an effect, define the Fx*SaveScen callback. For example, the fire effect saves itself like this:</text>
|
|
<code>global func FxFireSaveScen(object obj, proplist fx, proplist props)
|
|
{
|
|
// this is burning. Save incineration to scenario.
|
|
props->AddCall("Fire", obj, "Incinerate", fx.strength, fx.caused_by, fx.blasted, fx.incinerating_object);
|
|
return true;
|
|
}</code>
|
|
<text>obj and fx refer to the object and effect proplist as for any effect call. save_name is the variable name of the effected object and is unset for global effects.</text>
|
|
|
|
<h id="ScenSave">Scenario saving reference</h>
|
|
<text>The following functions are available to call on the "props" parameter passed to SaveScenarioObject callbacks:</text>
|
|
|
|
<h>AddCall</h>
|
|
<text><code>bool AddCall(string id, object target, string function, any par1, any par2, ...);</code></text>
|
|
<text>Adds a new call of format target->Function(par1, par2, ...) to the stored object script. Object parameters may be passed as is; strings must be quoted explicitely.</text>
|
|
<text>The id parameter is an identifier which can be used by derived objects to remove the property again.</text>
|
|
|
|
<h>Add</h>
|
|
<text><code>bool AddCall(string id, string script, any par1, any par2, ...);</code></text>
|
|
<text>Adds a custom script snippet of any format. script may contain format characters and parameters are formatted into the string using <funclink>Format</funclink>().</text>
|
|
|
|
<h>Remove</h>
|
|
<text><code>int Remove(string id);</code></text>
|
|
<text>Remove all strings added previously using AddCall or Add with the given ID. Can also be used to remove default properties. Returns number of script lines removed.</text>
|
|
|
|
<h>RemoveCreation</h>
|
|
<text><code>bool RemoveCreation();</code></text>
|
|
<text>Remove all strings added previously using with IDs SAVEOBJ_Creation or SAVEOBJ_ContentsCreation.</text>
|
|
|
|
<h>Clear</h>
|
|
<text><code>bool Clear();</code></text>
|
|
<text>Remove all creation and property setting strings.</text>
