How do I put global variable for a single obj

Hi,

I made some tank bots and their health is a global variable (=30)

if bullet on collision with bot , subtract 10 from bothealth.

But if I kill a bot and another had respawn the bouth bots are killed.

How must I make to kill just the hitted bot?

have I made something wrong?

Thanks.

You need to use an instance variable, not a global variable. Instance variables are set on and only affect an object. Global variables are non-specific, hence the name global. Each tank will have an instance variable called health with a starting value of 30. Then, only the tank whose variable reaches 0 will be destroyed.

Put the tank and turret in a container.
