repeating+Adding on script looks impossible?!

[Casotime1999]

but if you make an area with An AddEntityCollideCallback and you say at the cannon:
if the area matches with the cannon what should you do?
create the timer inside the block:
void OnStart()
{
AddEntityCollideCallback("", "cannon", "cannonshootArea", "ShootCannon", false);
}
void ShootCannon(string &in asParent, string &in asChild, int alState)
{
//inside this block you put the timerScript with a name
}
void exTimer(string &in asTimer)
{
if(asTimer=="name")
//AddPropForceScript
//Timer as the ball is turning off
if(asTimer=="name2")
{
//disable ball
//turn off the PropForce put as the coordinates as the cannon
//timer active the ball
}
if (asTimer=="Timeractiveball")
//SetEntityActive("ball", true);
//regive back the addPropForce
//reloop timer1
}
I tried to give a Hint but I think that is all you want(sorry for my bad english)
