When i put Sprite Buildings in my maps ... during the gameplay those building can't be killed .. how to make them with HP

You dont.

Don't do sprite buildings, just place normal buildings, you only use sprites when you are A: Using doodad sprites to cover up blocks, or just spice up a piece, B: Trying to get some other weird effect that requires using sprites, such as stacked units.

You could use the famous False Invincible technique. I dun remember how to do it, tho...
It's about setting the HP of a unit/building to a certain amount or something like that and it appear as invincible, but you can attack it

or you could just set it invincible using the trigger?? lol

Why were you using sprites initially?

Na, my point is that you can make it LOOK LIKE invincible, but you still can destroy it! >:D

Give it health over 9999

If you place sprite-units in a map you will have the properties of a normal building with properties of a sprite.

It can be clicked on, walked through/over, it cannot be affected by triggers, it can be attacked but whatever you do DO NOT KILL IT.

It will crash.

Why do you need this, anyways? Why can't you just use normal buildings? Are you trying to keep it melee for some reason?

I was able to kill and use triggers on them...

EDIT: Oh, that's when you place them as disabled sprites

So, sprites can generally be used with triggers if they're simply disabled?

Yup

More possibilities just opened up for me =P

I'm guessing this doesn't include weapon and spell sprites?

Most of them crash, or just don't appear, check out this list I made of all the effects.

Was just wondering if the red nuke dot worked, because i want to use it as a laser sight for a map i'm making.

Nah, it doesn't appear when you disable it It's not a unit sprite anyway, so you can't really disable it.

FINE.

=P

I s'pose i could mod the game to make a unit have the nuke dot graphics, but that would be hassle =P

What other effect could be used as a laser sight?

A red period

Without centering view =P

Exploding scourge/DA?
