Hi again, now well me to gone out a new mistake, for example in case of the trainer of hl2 when the life to find of freeman 100 and the direction happens to the trainer, in the game the enemies do not die either Ãƒâ€šÃ‚Â¿? Ãƒâ€šÃ‚Â¿? Where this my mistake? Thank you

the game uses the same routine to decreae life for enemies as it uses for you.
when you removed it you also removed it for the enemy.

There is no simple way to solve this, except using pointers or code injection

It exists in the forum algun manually to solve it or as example? thanks Wink

Xblade, post your asm instruction and I'll help...Code injection is fairly simple if you use the right "steps"...

Puedes hablar en espanol, translators SUK !

Ok I am going to write the values that there gives me for example the game Serious Sam 2 that it is with that I have the problem, despues if I learn it will apply them to the others, only I need an example.

Serious Sam 2:

Energy value my and enemy:

Value change a 200:

Memori View and assembler:

And in future already not what there that to do, and seen the tutorial but I cannot understand it due to the fact that not very well English and the translators are very bad, he(she) would be grateful that help me with this example thank you very much

I'm afraid you can't simply use code injection in an engine, except if you manage to make it inside the engine. Code-caves inside an engine are poor and very few Smile

I played SS2, and managed to only make an ammo hack. Health is a bit tricky, since the instructions it uses are directly implemented in the engine with especific functions...

Dark Byte is needed at this point. I can go on telling you how to code-inject, but as I tried and failed, I see no point in doing that...

And yes, I simply understand spanish. Can't write it well, but heh...

k it(he,she) costs(suits) help me to do since(as,like) the injection, if I trump not there problem it(he,she) returns to try(mean) Very Happy

, if you want you I add to the msn Smile

i close the cheat engine and re-open trainer and see this image:

Desesperation!!!!!!!!!!

only work con cheat engine open, i close CE an run trainer con the new code and not runnig the trainer!!!!!!!!!! Crying or Very sad

Dark Byte · Posted: Fri Oct 28, 2005 2:58 pm Post subject:

That is because the location of the dll changes and also the location of the code.

CE adjusts to that as long as you don't close it, but the trainer doesn't

That reminds me of an even greater problem. STRUCTURES. Is there any way to find let's say a pointer that tells me a direction, an address, and starting from that pointer with adding a certain offset to get to the correct module instruction, like in this case ?

Or better and simple put : there are games that use same routines for player/enemy healths. I found no differences in the code instructions being used [yeah, I managed to play as the enemy in the same game] and none differs...

My question : how does the game differentiate player/enemy if all instructions contain same registers all the time... ?

EX : WarHammer 4k. Building the same unit as player/enemy. If debugger used, i get some codes [being the player]. I find the address for the building bar for the enemy using breakpoints. Looked at what accesses both addresses [mine/enemy's] and found no differences at all [not a single register different - except the involved one containing player/enemy pointers]. Problem : pointers are DMA. If i start the game I won't be able to work it. Pointer changes...How do I retrieve it always and use it in the code-injection ????

look in the structure for the offset that determines what player is associated with it(you may have to traverse some other pointers), then determine what player you are, and compare. if it is a match, don't decrease health, if it isn't decrease the health or even just set it to 0 for all death
