Spell Targeting Issue

[Mr_Bean]

Hi guys. I have a spell in which the player targets a point and it creates an "energy fissure" (cool-looking void thingy) at the point. It then sends out waves which zap your mana. I use dummy casters to create the wave effect (purple version of "crushing wave"). Anyway, the issue is that sometimes the dummy cannot cast because it's target is on unpathable terrain.

Perhaps this will help to illustrate my issue:

Arrows: the effects (waves)
Oval: the energy fissure effect

The effect that travels east wouldn't be cast because its target would be the fence, which is unpathable.

I guess my question is: how do I ensure that the dummy ability will ALWAYS be cast i.e. how to make the spell able to target even unpathable terrain?

If I am too vague, please say so and I will explain more! If you like, I can upload an in-game screenshot so you can see what I am talking about.

Thanks for reading, hope you can help!

You could always check conditions and just really quickly turn on pathing for that one point and turn it back off right after the spell has been cast... but it would pose a slight chance of a unit getting stuck there.

Thanks, this works well!

Just a query: with JASS does it apply to all the pathing types that are equal to the type at point (x; y)?

call SetTerrainPathable(x, y, PATHING_TYPE_WALKABILITY, true)

It makes the pathing type of the cell the point is in to be the one you specify.

Oh okay, thanks.
