Several questions

1. How do you change the max speed? game constants wont let you even though it has that value. (why have it in there???)

2. How do you change animation sizes and/or speeds of spell graphics? ex-neutral building explosion is always the same size when i make its effect through create special effect, and so is thunderclap (want to increase range but graphic doesnt reach)

3. I want to make a spell based off of disease cloud that makes units affected by the disease have a blind effect (curse)

4. Making an AoE blind spell

5. a spell where dark tendrils lash out and damage everything in range and puts a dot on them (like phoenix fire but it hits them at the same time and only goes when you cast it)

6. How do you trigger buff/debuff spells? Cant find anything in gui to do this

7. A spell that only hits units with a specific debuff on them, no matter how far away, like a channeling debuff (probably easy to trigger the debuff on marked guys when your channeling but...id have to know #6 for that)

Thanks in advance.

If you want to alter a value in game constants, you need to check "use custom gameplay constants" in the upper corner.

I did that, the speed values have a maximum maximum cap it seems, but i could swear ive seen maps where units move realy fast.

well each unit has a base speed, as well as a min max, you have to raise the max or base for them to move faster than default. 270 is the average default speed.

to 1. and 2. As far as I know the easiest way to change the size of special effects is to attach them to a dummy unit without a model and change the units size
to 6. you need to create a dummy unit that casts an ability with your buff on the unit you want to "trigger" buffs

to 3. what do you understand under a blind effect? in case I got you right you could make a dummy cast curse on the target units

I hope you can forgive me for advertising but I would suggest you to take a look at vexorians caster system since this covers many of your questioned aspects (eg. fast unit movement, aoe spell helpers, dummy unit, etc)

That value cant be set higher than the game constants maximum. Neither of them go past 522, i have a spell with a dummy unit that needs to move. its a fireball. but a fireball that moves as fast as its caster (if you have a speed buff) doesnt look right, i wonder if i can trigger it to move faster...

@ tamisrah, even if i set cast time cooldown and mana cost to nothing, the dummy unit can only cast the spell once, + it wont even do that cause it doesnt know what unit to cast on.
I used pick every unit with debuff for #3 and 4 and #6 works only on one unit and its not removeable (want it to stop the trigger if i stop channeling)

I tried to make the aoe blind like this- based off howl of terror debuff set to 0- when i cast that spell it waits .1s for the debuff then uses triggers to create a dummy unit to cast its blind spell (based on curse) on all units with debuff, but pick every unit isnt making it cast

Use a repeating timer. Every 0.033 seconds, move the dummy unit to the position of the caster and, if need be, change its facing angle.

Read "On Dummy Casters".

Can you explain that in a bit more coherant terms?


Oh, and I merged your triple-post.
