Class TLevelLogic

Warning: this symbol is deprecated: create and prepare TCastleScene instance directly

Load scene from file, doing common tasks.

• optionally create triangle octree

• call PrepareResources, with prRenderSelf, prBoundingBox, prShadowVolume (if shadow volumes possible at all in this OpenGL context),

• Free texture data, since they will not be needed anymore

Warning: this symbol is deprecated: create and prepare TCastleScene instance directly

Handle a placeholder named in external modeler. Return True if this is indeed a recognized placeholder name, and it was handled and relevant shape should be removed from level geometry (to not be rendered).

Called after all placeholders have been processed, that is after TLevel.Load placed initial creatures, items and other stuff on the level. Override it to do anything you want.

Create new level instance. Called before resources (creatures and items) are initialized (override PlaceholdersEnd if you need to do something after creatures and items are added). You can modify MainScene contents here.

Parameters

Level

Instance of TLevel, in particular with the root of level transformation in Level.RootTransform.

The created TLevelLogic instance will be added to this Level.RootTransform, and it must stay there always.

Passing it in constructor is necessary, as TLevelLogic descendants at construction may actually modify your world, and depend on it later.

DOMElement

An XML tree of level.xml file. You can read it however you want, to handle additional attributes in level.xml. You can use standard FPC DOM unit and classes, and add a handful of simple comfortable routines in CastleXMLUtils unit, for example you can use this to read a string attribute:

MyAttribute := DOMElement.AttributeStringDef('my_attribute', 'default value');
MyRequiredAttribute := DOMElement.AttributeString('my_required_attribute');

Called when new player starts new game on this level. This may be used to equip the player with some basic weapon / items.

This is never called or used by the engine itself. This does nothing in the default TLevelLogic class implementation.

Your particular game, where you can best decide when the player "starts a new game" and when the player merely "continues the previous game", may call it. And you may override this in your TLevelLogic descendants to equip the player.

Level that we are part of.

Time of the level, in seconds. Time 0 when level is created. This is updated in our Update.
