i am trying to create a shield drainer and i have been trying for two days now to make the damage effect of it constant for a period of 10 seconds before fading. Will someone please tell me how to accomplish this.

use an effect which does a damage effect every half a second for 10 seconds.

you do it by creating 20 new of the thing over the parts section, apply seconds to it (controls how much time it takes to active after the effect is actived)

then add the damage effect to each one and other fancy stuff if you want to.

enjoy.
