Pressing Keys in a Specific Order
Hi! I am making a game involving magic and I have a great idea how to cast spells. But I don't know what to write. This is what I want the console to say (not exactly).
//User pressed and is holding E, Starting Spell recognision
//Pressed LeftClick
//Pressed LeftClick
//Pressed RightClick
//Pressed LeftClick
//User let go of E, Recognising spell
//Spell is "Fire", Casting spell
BTW: Code can be in any language as long as you explain what each part does and what I need to change to add more spells.
Please accept my answer if it helped, otherwise give me more information. This hurts my answer acceptance rate.
Use Input.GetKeyDown and Input.GetKeyUp to determine when the user starts and stops holding the 'E' key down.
Then use Input.GetMouseButtonDown while E is being pressed to read mouse clicks. Note that:
button values are 0 for left button, 1 for right button, 2 for the middle button.
While tracking the clicks, add 'L' and 'R' to a "Spell String".
Then you just have to check it against your library of spell strings.
var fireBallSpell = "LLRLLRRL";
if(inputSpell == fireBallSpell)
{
castFireBall();
}
Thank you, since you don't have to check anything until after a key is released, you can simplify it quite a bit. And you can actually create a dictionary to register spell strings to objects.
"LRLRLRLLLLR" => "FireBallScriptComponent"
$$anonymous$$ake all spell scripts derive from a single parent class with an abstract method Cast();
Then you can do:
if(this.spellBook.Contains$$anonymous$$ey(spellString))
{
((SpellScript)gameObject.GetComponent(this.spellBook[spellString])).Cast();
}
Very cool. The Lambda expression is a little too deep for most beginners but great method.
This can just be solved with bools or stages. User holding down E can be handled like so
private bool eIsHeldDown = false;
public int FireSpellStage = 0;
void Update(){
eIsHeldDown = Input.GetKey(KeyCode.E);
if(eIsHeldDown){
if(FireSpellStage == 0 ){
if(Input.GetKeyDown(KeyCode.F)){
FireSpellStage = 1;
}
else if (FireSpellStage == 0){
if(Input.GetKeyDown(KeyCode.I)){
FireSpellStage = 0;
}
}
// And So on, till you made a combo you like.
}
}
else{
if(FireSpellStage == 4){
Debug.Log("Casting Fire Spell");
}
FireSpellStage = 0;
}
}
