well i got how to pull the target to the position of the caster but now... how to make it be pulled foward so that i can finish my spell

pulling forward == pushing?
I think you got the idea from pharaos link on how to move units, so just simply reverse the direction?
I dont know how its done in the sample but it should be something with adding 180 degrees to the angle or negate the value.

yeah that's right i'm dumb so i didn't figured it out before... and sorry for my bad english also to correct myself i don't mean jass on the first post... i meant GUI and MUI
