- Sun 10 Feb 2019, 19:05 #70600 Hi guys,
How can I code the below:
When 'sprite1' is created, add 1 to global variable 'number', I would also like to 'add 1' every 1 second.
I have tried looking but the tutorials I have found are only on scoring & player health.
Thanks in advance.

- Mon 11 Feb 2019, 02:46 #70610 Do you want 1 to be added every second only when sprite 1 exists? If so you would have conditions something like:

The number of sprite1>0
The timer "incscore" is greater than 1 seconds

and actions:

Do +1 to global variable number
Reset the timer "incscore"

An alternative any time you want to do something per second is to use TimeDelta(). This simplifies the event to
Conditions:
The number of sprite1>0
Actions:
Do +1*TimeDelta() to global variable number

I will try that, thanks again bud.
Jim.

- Mon 11 Feb 2019, 13:43 #70617 Thanks, but I am stuck at the beggining, whats the first condition I should use for 'The number of sprite1>0'
I cannot find anyhting like 'at the begging' - 'number'
Sorry,
Thanks
Jim

- Mon 11 Feb 2019, 14:56 #70619 In case you want two events separated:

When 'sprite1' is created, add 1 to global variable 'number'

There's no condition to check if an object has been created, the best way is to add the actions (in this case increase the variable) in the same event where you create the object:

Code: Select allConditions: The conditions in the event you create the Sprite
Actions: Create object Sprite
         Do + 1 to scene variable "number"

I would also like to 'add 1' every 1 second

As explained by MattLB, every second increase the variable:

Code: Select allConditions: Timer "increase_variable" is greater than 1 second
Actions: Do + 1 to scene variable "number"
         Reset timer "increase_variable"

I should be studying now :/

- Mon 11 Feb 2019, 15:19 #70622 Thanks guys, nearly there!
Still not working though?
Please see attached image.
'money' is a text sprite with '0' in it, I dont have the option to update the GV 'number'.
Thanks again

- Mon 11 Feb 2019, 16:10 #70623 You aren't increasing the variable in the second event but in the first one only.
Also, how do you know it isn't working?, note that you're increasing a global variable "number", not a scene variable

I should be studying now :/

- Mon 11 Feb 2019, 16:17 #70624 I have added the code to the 2nd event, thanks.
It is only 1 level, so I thought Global would be fine, is it?
I can swap to scene if that works.
I know it not working, as I am waiting 1 second and the 'money' is not going up.
Thanks again.

- Mon 11 Feb 2019, 16:45 #70625 Using global variables is ok, just want to make sure that you know what you're doing

I know it not working, as I am waiting 1 second and the 'money' is not going up.

But what is the action that updates the money object?, there's no magic, you update the variable but you've to do something extra to show that on screen (or use the debugger), that's why I'm asking how you know it doesn't work.

For example if "money" is a text object, after updating the variable you can add this action to update the money text:

Code: Select allDo = GlobalVariableString(number) to the text of money (text object)

I should be studying now :/

I can’t get the right expression!
That’s the hardest bit in Gdevelop.
I have tried all these (I know I should only have 1 but I was trying to replicate your code)
