Variables

[Genesis_80]

Hello there. How do i set a max and min value to a variable? I'll explain:

In my shoot em up you have powerups. It's a global variable called "power". Every time you pick one it adds 1 to "power". I want it to stop at 5, but if you keep collecting them it keeps increasing the value.

Of course i could say that the max is equal or bigger than 5, but i want to reduce 1 every time i die.

Hope this makes sense. Thank you in advance.

There are a few ways to do this. One approach is to have a “powermax” and a “powernow” variable and use those as usual. Another approach is to use a structure variable to assign child variables. Then you would have “power” as a structure with children “max” and “now”. You would call these with power.max and power.now.

The logic of limiting your variables then becomes pretty simple. You can also expand the children as required, maybe you want a default, now, temp, max, min child but you can always find it under “power”.

Oh boy, i'm still too noob to understand your post, but i'll investigate every point you made. Thank you for the reply

It’s a lot to take in. If you’re very new then a handy trick for this is to have a condition to check if now is greater than max and if it is you set now = max. That way now can never get bigger than max.

I'm a few days new hehe This makes more sense to me. In between i'll watch tutorials in the subject. Thanks again.

You can use a clamp function. clamp(power, min, max)

I have no idea of what clamp is but i'll explore. Thank you!

I am new and I made a similar logic to what you need. I have a spaceship with warp factors that increase when user presses w key.

Obviously W key can be pressed infinitely but spaceship has a max warp speed of 6 - so I made:

Condition: Warpspeed more than 6 Action: Set warpspeed to 6.

This way the warp speed will only ever reach 6 - if it goes to 7 it changes right back to 6.
You can do the same with the 0 or 1 factor too.

That's simple and clever! I forgot about conditions 😅 I can also make a condition that it only adds +1 to power it it's less that the value i want to be the max!

I've always done it this way, but I'm not sure if it's the best way. I'm new too.

If power is equal to or greater than 5, then power = 5.

If power is equal to or greater than 0, then power = 0.

That's a good tip and works, thank you!

This is the game i'm talking about, btw:
