Class RuleTexture Extends GridGraphRule

Public

Modifies nodes based on the contents of a texture.

This can be used to "paint" penalties or walkability using an external program such as Photoshop.

This rule will pick up changes made to the texture during runtime, assuming theTexture.imageContentsHash property is changed. This is not always done automatically, so you may have to e.g. increment that property manually if you are doing changes to the texture via code. Any changes will be applied when the graph is scanned, or a graph update is performed.

Penalty	Penalty goes from 0 to channelScale depending on the channel value.
Position	Node Y coordinate goes from 0 to channelScale depending on the channel value.
WalkablePenalty	If channel value is zero the node is made unwalkable, penalty goes from 0 to channelScale depending on the channel value.
Walkable	If channel value is zero the node is made unwalkable.

BeforeCollision	Before the collision testing phase but after height testing. This is very early. Most data is not valid by this point. You can use this if you want to modify the node positions and still have it picked up by the collision testing code.
BeforeConnections	Before connections are calculated. At this point height testing and collision testing has been done (if they are enabled). This is the most common pass to use. If you are modifying walkability here then connections and erosion will be calculated properly.
AfterConnections	After connections are calculated. If you are modifying connections directly you should do that in this pass. Note If erosion is used then this pass will be executed twice. One time before erosion and one time after erosion when the connections are calculated again.
AfterErosion	After erosion is calculated but before connections have been recalculated. If no erosion is used then this pass will not be executed.
PostProcess	After everything else. This pass is executed after everything else is done. You should not modify walkability in this pass because then the node connections will not be up to date.
AfterApplied	After the graph update has been applied to the graph. This pass can only be added as a main-thread pass. If many updates are applied to the graph at the same time, this pass will only execute once after all updates have been applied. Warning No data in the context except the reference to the graph is valid at this point. It has all been disposed. You cannot modify any data in this pass.
