Hi,
I would like to draw area spell circle indicator on the floor surface before casting magic spell, but I have no idea how to draw texture in real-time in order to allow player choose where to cast. Any ideas, blueprint or c++ excerpts are more than welcome.
Thanks in advance.
This is an example texture:
The simplest way to do it would be to convert the texture to a sprite w/o collision and just place it at the bottom of the player’s feet.
Decals would likely serve you best here…it’ll draw on the floor and will include some normal maps the ground has in case you’ve small rocks or something it’ll take that info into account to look much better…
If you’re rather new the best way to get one up and running would be use Epic’s Decal from their Content Examples…comes with the engine…Just go to their Decals Level or Materials Level (can’t remember where they are currently but should be one of those two) click on a decal, find in content browser, right click the asset in the content browser and go to asset actions you’ll see Migrate from there…migrate the Decal to your projects Content folder…Sounds like a lot of steps but it’s only 15secs once the level is loaded…
Replace their Decal pic with your own…look up opacity if any more than just the green shows up like that picture above, you should not see the square the circle is drawn on…
Anyways, once you get to that migrate button you’ll use it all the time, Epic’s got some amazing stuff lying around example projects that are freely given out with the engine…in fact once you get a little more comfortable I suggest you take a peak at the Sigil Particle effect from the Elemental demo
