unity3d - Set material color with unity C# -

-

i working on game in unity. game far have 3 cubes wish target. have them set in array , when hit tab targets switch between them based on distance. fine have run pickle , wish have cubes target turn red visual representation. seen on youtube people used following line of code :

selectedtarget.renderer.material.color = color.red;

however not work me. seen comment saying : function render deprecated. below should work...

selectedtarget.getcomponent<renderer>().material.color = color.red;

this code not work me either. no errors mind you, runs fine cubes not turn red. has idea on whether or not doing right? post entire script below , code on in selectedtarget(). appreciated , thank you!

private void selecttarget(){     selectedtarget.renderer.material.color = color.red; }

i had very same problem. had no errors. need able set color property on material, , shaders have color property. had use example self-illuminated/bumped instead of mobile/vertexlit. changing color should fine can see main color property in editor/inspector.

also make sure mesh has materials. if don't have materials, if it's blank or placeholder else won't work! i'd create texture preferably white colored , small 5x5. attach texture cube. after attach can color it!

i've done cool stuff in game color.lerp, it'll fade 1 color next! example below ping pongs white red when player hit enemy indicating damage!

transform.renderer.material.color = color.lerp(color.white, color.red, mathf.pingpong(time.time * 3 * speedlerp, 1.0));

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
