Help with spawning a random enemy

Hi, i am training construct, and its quite awesome, but i have a problem, i wanted to create a button that when we clicked, it starts a timer and at each second it has a change of spawning an enemy, i know it has something to do with time delta, and some random variable, that if the random variable equal to 1 for example, it turns the enemy visible or spawn an object, but im trying but i cant make it works, can someone help me plz?

Thank you

Try a group.

On object clicked

->system set group "spawn" enabled

-group "spawn"

every xxxxx miliseconds

-> system create object enemy at random() x,y

newts would work

also just as easy would be a global variable ('spawningon')

if ('spawningon') = 1

system create enemy

also if you want the enemy to be random, put all the enemies in a family

let's say you put them in a family called enemies

if you create object "enemies"

it will choose something from the family at random to create

Just one question, where i create a group?

Thank you again for the help

right click where you would create events

create group instead

honestly if the enemy spawning thing is the only thing the group will do, I see no reason to use a group instead of a pv, groups are more suited to large sequences of events, not just one simple action

just use a global or private variable, I would suggest

but do go ahead and test out groups anyway so you can see what they are

Im sorry but cant do it, cant find the IF statement, only find Else OR While, im new to this and im sorry but u both talk as if i know about construct sorry but thank you anyways.

Try the ghost shooter tutorial linked on the main scirra site

To learn the basics

The IF statement in construct is actually called a "Compare" your looking for System -> Compare Global Variable

I already did the ghost tutorial about 1 week ago and did other 2 tutorials, but finally i could do it thank you all for the help.
