Tower Defense Starter Kit

In order to activate Global Abilities, the actors that support targeting on their surfaces need to satisfy two conditions:

  1. The targetable surface needs to have the actor tag ‘GlobalAbilityTarget’. This conditions determines if the ability can be deployed on a particular surface or not.

  2. It should block the ‘GlobalAbilityTargeting’ trace channel. Apart from the normally targetable surfaces like the AI Path meshes, this condition is also satisfied by the Kill Z volume as it helps the players track the reticule even when they the mouse cursor is focused on empty spaces as shown below:

So basically the reticule remains white on areas like these where the ability cannot be deployed, & turns to red on deployable surfaces based on condition 1) like the AI path meshes.

And as for the lack of grid cell detection, could you try moving the Kill Z Volume actor a few thousand units below it’s current position. It blocks all types of traces & I just want to make sure that it isn’t blocking the traces before they hit the grid cells.
