Class RulePerLayerModifications Extends GridGraphRule

Public

Modifies nodes based on the layer of the surface under the node.

You can for example make all surfaces with a specific layer make the nodes get a specific tag.

This uses the information from the height testing system to determine which layer the surface is on. As a consequence, this rule does not do anything when using 2D physics, or height testing is disabled on the grid graph.

Pass

Where in the scanning process a rule will be executed.

Pass

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.

Check the documentation for GridGraphScanData to see which data fields are valid in which passes.

SetDirty ()

Call if you have changed any setting of the rule.

enabled

Only enabled rules are executed.

SetTag	Sets the tag of all affected nodes to PerLayerRule.tag.
MakeUnwalkable	Makes all affected nodes unwalkable.
