if you want a timer floating text, use another trigger for the loop of it...
i'm asking how to create the floating text when begins casting ability with casting time,it shows the floating text after the casting time expires,i'm asking how to make the floating text to show before the casting time expires,as i said in the second when i order to cast the spell.
Strange, if you want float text at EXACT time when the spell is cast above the casting unit.. no timers, no nothing... it should work like other users said
Try adding a 0.5 second pre-casting time at the ability and setting the "Begins casting - an ability" ... that might work
Oh sry for my grammar and yes thats what i want > begins Casting silenbce >>>Timer for 5 seconds appear >>after expires then silence effect..but in my map it's not silence effect,but the spell is based on silence.
